Die Erfindung betrifft eine Universalroessschablone für Anuloplastieringe zur Wahl der optimalen Größe eines Anuloplastierings vor seiner Implantation.The invention relates to a universal size template for annuloplasty rings for selecting the optimal size of an annuloplasty ring before its implantation.
Anuloplastieprothesen werden bei Herzklappeninsuffizienzen zur Umgehung der Implantation einer künstlichen Herzklappe, meist in atrioventrikulärer Position, eingesetzt. Der atrioventrikuläre Anulus ist eine dynamische Struktur, die während des Herzzyklus Änderungen in Größe und Form unterliegt. Während der Systole verringert sich insbesondere der mittlere Anulusdurchmesser der Mitralklappe durch eine posteriore Anularkontraktion, während die anteriore Anularlänge nahezu unverändert bleibt. Falls eine systolische anteriore anulare Bewegung vorliegt, und darüber hinaus ein zu großes posteriores Klappensegel existiert, kann es zu Behinderungen des linksventrikulären Auswurfs kommen.Annuloplasty prostheses are used in cases of heart valve insufficiency to avoid the implantation of an artificial heart valve, usually in the atrioventricular position. The atrioventricular annulus is a dynamic structure that undergoes changes in size and shape during the cardiac cycle. During systole, the mean annulus diameter of the mitral valve in particular decreases due to posterior annular contraction, while the anterior annular length remains almost unchanged. If there is systolic anterior annular movement and, in addition, the posterior valve leaflet is too large, this can lead to impairments of left ventricular ejection.
Zu den anuloplastisch therapierbaren Insuffizienzen gehört vor allem der nicht stenotisch bedingte Verlust an Schlagvolumen, hervorgerufen durch überhöhten systolischen Rückfluss des Bluts durch die Mitral- bzw. Triskuspidalklappe in den entsprechenden Vorhof.The insufficiencies that can be treated with annuloplasty include, above all, the non-stenotic loss of stroke volume, caused by excessive systolic backflow of blood through the mitral or triscuspid valve into the corresponding atrium.
G 9924 DE - 2 -G 9924 EN - 2 -
Ziel der Mitral- bzw. Trikuspidalklappenrekonstruktion durch Implantation einer Änuloplastieprothese ist die Schaffung einer möglichst breiten Koaptationsflache der Klappensegel und eine Gewebeentlastung während der Systole sowie eine gute Hämodynamik während der Diastole. Dies beinhaltet die Korrektur der Dilatation und/oder Deformation des Anulus, die selektive Reduktion deformierter Bereiche der Klappensegel, sowie die Prävention von wiederkehrenden Dilatationen und Deformationen. The aim of mitral or tricuspid valve reconstruction by implanting an annuloplasty prosthesis is to create the widest possible coaptation area of the valve leaflets and to relieve tissue pressure during systole as well as to achieve good hemodynamics during diastole. This includes the correction of dilatation and/or deformation of the annulus, the selective reduction of deformed areas of the valve leaflets, and the prevention of recurrent dilatations and deformations.
Die zur Anwendung kommende Änuloplastieprothese liegt in Form eines offenen oder bis auf einen Spalt geschlossenen Rings vor.The annuloplasty prosthesis used is in the form of an open ring or a ring that is closed except for a gap.
Diese Anuloplastieringe müssen in ihrer Größe auf die Größe des Herzens bzw. der Öffnungen, in die sie eingesetzt werden, ausgewählt werden. Dies erfolgt bisher vor der Implantation des Anuloplastierings mit Hilfe von transparenten Messschablonen, wie das beispielsweise in der Veröffentlichung von Carpentier, A. et al. mit dem Titel "A New Reconstructive Operation For Correction of Mitral and Tricuspid Insufficiency" in J. Thorac. Cardiovasc. Surg., 6 (1): 113, 1971 beschrieben ist. Für die Wahl der optimalen Anuloplastieringgröße wird auf die Verwendung von mehrteiligen Messschablonensätzen zurückgegriffen, bei denen für jede Ringgröße eine entsprechende Messschablone vorhanden ist. Solche Messschablonensätze sind beispielsweise von den Firmen Baxter Healthcare Corporation, Edwards CVS Division, 17221 Red Hill Avenue Irvine, CA; St. Jude Medical, One Lillehei Plaza, St. Paul, Minnesota; Medtronic Inc. 7000 Central Avenue, NE Minneapolis, MN und Aor Tech International PLC, Strathclyde Business Park, Strathclyde, Schottland erhältlich.The size of these annuloplasty rings must be selected based on the size of the heart or the openings into which they are inserted. This has previously been done before the annuloplasty ring is implanted using transparent measuring templates, as described, for example, in the publication by Carpentier, A. et al. entitled "A New Reconstructive Operation For Correction of Mitral and Tricuspid Insufficiency" in J. Thorac. Cardiovasc. Surg., 6 (1): 113, 1971. To select the optimal annuloplasty ring size, multi-part measuring template sets are used, which have a corresponding measuring template for each ring size. Such measuring template sets are available, for example, from the companies Baxter Healthcare Corporation, Edwards CVS Division, 17221 Red Hill Avenue Irvine, CA; St. Jude Medical, One Lillehei Plaza, St. Paul, Minnesota; Medtronic Inc. 7000 Central Avenue, NE Minneapolis, MN and Aor Tech International PLC, Strathclyde Business Park, Strathclyde, Scotland.

Diese bisher bekannten Messschablonensätze bestehen aus bis zu acht Einzelschablonen. Dies bedeutet einerseits einen hohen Material- und Verpackungsaufwand, der die Herstellungskosten jedes Messschablonensatzes in die Höhe treibt. Auch besteht die Gefahr, dass die einzelnen Messschablonen des Messschablonensatzes falsch zusammengestellt werden, oder dass während der Anwendung oder Lagerung einzelne Messschablonen verloren gehen, ohne dass dies vor allem von nicht routinierten Anwendern erkannt wird.These previously known measuring template sets consist of up to eight individual templates. On the one hand, this means a high material and packaging expenditure, which drives up the production costs of each measuring template set. There is also the risk that the individual measuring templates in the measuring template set are put together incorrectly, or that individual measuring templates are lost during use or storage without this being noticed, especially by non-experienced users.
Der Erfindung liegt die Aufgabe zugrunde, eine Universalmessschablone anzugeben, die die bisherigen Messschablonensätze ersetzt.The invention is based on the object of specifying a universal measuring template which replaces the previous measuring template sets.
Die gestellte Aufgabe wird mit der Universalraessschablone durch die im kennzeichnenden Teil des Hauptanspruchs aufgeführten Merkmale gelöst. Die Unteransprüche geben bevorzugte Weiterbildungen an.The stated problem is solved with the universal measuring template by the features listed in the characterizing part of the main claim. The subclaims specify preferred further developments.
Bei der erfindungsgemäßen Universalmessschablone sind die Umfangskonturen und Größenkennzahlen eines mehrteiligen konventionellen Schablonensatzes beispielsweise durch einen Aufdruck oder eine Eingravierung gekennzeichnet. Die äußere Umfangskontur der Universalmessschablone entspricht der Umfangskontur der größten Messschablone eines konventionellen Messschablonensatzes. Die vorzugsweise transparente Universalmessschablone weist vorteilhafterweise eine Befestigungsmöglichkeit für einen Handgriff auf, mit dem die Universalmessschablone gehalten werden kann. Es können statt der Befestigungsmöglichkeit für einen Handgriff auch öffnungen vorgesehen sein, in die man beispielsweise mit einer Pinzette eingreifen kann, um die Universalmessschablone zu positionieren.In the universal measuring template according to the invention, the peripheral contours and size codes of a multi-part conventional template set are marked, for example, by a print or an engraving. The outer peripheral contour of the universal measuring template corresponds to the peripheral contour of the largest measuring template of a conventional measuring template set. The preferably transparent universal measuring template advantageously has a fastening option for a handle with which the universal measuring template can be held. Instead of the fastening option for a handle, openings can also be provided into which one can reach with tweezers, for example, in order to position the universal measuring template.

Ein Ausführungsbeispiel einer erfindungsgemäß ausgebildeten Universalmessschablone wird nachfolgend anhand der beiliegenden Zeichnung erläutert.An embodiment of a universal measuring template designed according to the invention is explained below with reference to the accompanying drawing.

Fig. 1 zeigt eine perspektivische Ansicht einer Ausführungsform der erfindungsgemäßen Universalmessschablone 1 für die Bestimmung der Größe eines zu implantierenden Anuloplastierings. Die Umfangskontur 4 der Universalmessschablone 1 entspricht dabei dem größten zur Verfügung stehenden Anuloplastiering und damit der größten Messschablone eines konventionellen Messschablonensatzes. Die Universalmessschablone weist weiter an der hier oberen linken Ecke der Umfangskontur eine Bezugskante 2a auf. Am gleichen oberen Rand sind auf der gegenüberliegenden Seite Messkerben 2b angebracht. Diese kennzeichnen die Ausmaße der kleineren, zur Verfügung stehenden Anuloplastieringe. Die Größe wird dabei zwischen der Bezugskante 2a und der jeweiligen Messkerbe 2b gemessen. Statt der hier dargestellten Messkerben 2b können natürlich auch beliebige andere Markierungen, wie beispielsweise aufgedruckte oder eingravierte Striche, verwendet werden. Um es dem Anwender zu erleichtern, sich die Form des Anuloplastierings besser vorzustellen, können auf der Schablone auch die Umfangskonturen der verschieden großen Anuloplastieringe aufgedruckt oderFig. 1 shows a perspective view of an embodiment of the universal measuring template 1 according to the invention for determining the size of an annuloplasty ring to be implanted. The peripheral contour 4 of the universal measuring template 1 corresponds to the largest annuloplasty ring available and thus to the largest measuring template of a conventional measuring template set. The universal measuring template also has a reference edge 2a on the upper left corner of the peripheral contour. Measuring notches 2b are attached to the same upper edge on the opposite side. These indicate the dimensions of the smaller annuloplasty rings available. The size is measured between the reference edge 2a and the respective measuring notch 2b. Instead of the measuring notches 2b shown here, any other markings, such as printed or engraved lines, can of course also be used. To make it easier for the user to imagine the shape of the annuloplasty ring, the circumferential contours of the different sized annuloplasty rings can also be printed or

eingraviert sein, wie das hier durch die angedeuteten inneren Umfangskonturen 3 angedeutet ist. Die Umfangskonturen der verschieden großen Anuloplastieringe sind dann noch mit Größenkennzahlen 7 gekennzeichnet, sodass der mit der Universalschablone 1 in seiner Größe ermittelte Anuloplastiering eindeutig ausgewählt werden kann.engraved, as indicated here by the indicated inner circumferential contours 3. The circumferential contours of the various sized annuloplasty rings are then marked with size codes 7 so that the annuloplasty ring whose size is determined using the universal template 1 can be clearly selected.
Zur Handhabung der Universalschablone ist vorteilhafterweise ungefähr in der Mitte der Universalschablone eine Öffnung 5 angeordnet, in der man einen Halterhandgriff beispielsweise durch Einschrauben befestigen kann. Es können auch weitere Öffnungen, wie die hier eingezeichnete Öffnung 6, vorgesehen sein, in die man beispielsweise mit einer Pinzette eingreifen kann, um die Universalschablone in den gewünschten Herzöffnungen zu platzieren.To handle the universal template, an opening 5 is advantageously arranged approximately in the middle of the universal template, into which a holder handle can be attached, for example by screwing it in. Other openings, such as the opening 6 shown here, can also be provided, into which one can reach, for example, with tweezers, in order to place the universal template in the desired heart openings.
Fig. 2 zeigt den Gebrauch der Universalmessschablone 1 zur Messung des intertrigonalen Abstands einer Mitralklappe. Der intertrigonale Abstand ist der Abstand zwischen den Eckpunkten 8a und 8b der Trigona fibrosa. Zur Bestimmung der passenden Größe des Anuloplastierings wird die Universalmessschablone 1, vorzugsweise mit dem an ihr befestigten Halterhandgriff 9 in die Mitralklappe eingeführt. Das vordere Mitralsegel wird leicht gestrafft, um dessen Basis freizulegen. Mit der Universalmessschablone 1 kann somit die Größe des Anuloplastierings, der am genauesten dem intertrigonalen Abstand (Abstand zwischen 8a und 8b) entspricht, bestimmt werden.Fig. 2 shows the use of the universal measuring template 1 to measure the intertrigonal distance of a mitral valve. The intertrigonal distance is the distance between the corner points 8a and 8b of the trigona fibrosa. To determine the appropriate size of the annuloplasty ring, the universal measuring template 1 is inserted into the mitral valve, preferably with the holder handle 9 attached to it. The anterior mitral leaflet is slightly tightened to expose its base. The universal measuring template 1 can thus be used to determine the size of the annuloplasty ring that most accurately corresponds to the intertrigonal distance (distance between 8a and 8b).
Fig. 3 zeigt den Gebrauch der Universalmessschablone 1 zur Messung der Größe des vorderen Mitralsegels 10. Dazu werden die Chordae tendinae 11 des Papillarmuskels leicht gestrafft und dann die Universalmessschablone 1 in die Nähe des vorderen Mitralsegels 10 gebracht. Die Umfangskontur auf der Universalmessschablone 1, deren äußerer Verlauf und deren Fläche am ehesten der Mitralsegelflache entspricht, gibt dann die ge-Fig. 3 shows the use of the universal measuring template 1 to measure the size of the anterior mitral leaflet 10. To do this, the chordae tendinae 11 of the papillary muscle are slightly tightened and then the universal measuring template 1 is brought close to the anterior mitral leaflet 10. The circumferential contour on the universal measuring template 1, the outer course and the area of which most closely correspond to the mitral leaflet area, then gives the
G 9924 DE - 6 -G 9924 EN - 6 -
suchte Größe des Anuloplastierings an.sought size of the annuloplasty ring.
Die Universalmessschablone kann auch für die Bestimmung der Größe des einzusetzenden Anuloplastierings bei einer Trikuspidalrekonstruktion verwendet werden. Dabei muß der Abstand der Messkerben 2a, 2b oder Messmarkierungen der Universalmessschablone 1 mit der Länge der anterioseptalen und posteriorseptalen Kommissur übereinstimmen.The universal measuring template can also be used to determine the size of the annuloplasty ring to be used in a tricuspid reconstruction. The distance between the measuring notches 2a, 2b or measuring markings on the universal measuring template 1 must correspond to the length of the anterioseptal and posterior septal commissure.
Die Universalmessschablone 1 kann weiter für die Größenbestimmung des vorderen Trikuspidalsegels eingesetzt werden. Dazu wird das vordere Trikuspidalsegel aufgefaltet und die Segelfläche mit der entsprechenden Messschablone abgedeckt. Die Umfangskontur 3, 4 der Universalmessschablone 1, die am ehesten der Länge der Komraissuren und der Fläche des vorderen Trikuspidalssegels entspricht, gibt dann die optimale Größe des Anuloplastierings an.The universal measuring template 1 can also be used to determine the size of the anterior tricuspid leaflet. To do this, the anterior tricuspid leaflet is unfolded and the leaflet area is covered with the corresponding measuring template. The circumferential contour 3, 4 of the universal measuring template 1, which most closely corresponds to the length of the compressions and the area of the anterior tricuspid leaflet, then indicates the optimal size of the annuloplasty ring.
Insgesamt liefert die vorliegende Erfindung eine Universalmessschablone, die im Vergleich zu konventionellen Messschablonensätzen folgende Vorteile aufweist: Es ist nur ein einziger Messvorgang notwendig. Der Anwender hat eine direkte, quantitative Vergleichsmöglichkeit der optimalen Größe des Anuloplastierings mit benachbarten Ringgrößen. Diese Vergleichsmöglichkeit ist gerade auch während der Lernphase von noch nicht routinierten Anwendern sehr vorteilhaft. Durch den Ersatz der konventionellen Messschablonensätze durch eine Universalmessschablone können Herstellungskosten und der Verpackungsaufwand vermindert werden. Außerdem werden Verwechslungen bei der Zusammenstellung der Messschablonensätze vermieden. Overall, the present invention provides a universal measuring template that has the following advantages compared to conventional measuring template sets: Only a single measuring process is necessary. The user has a direct, quantitative comparison of the optimal size of the annuloplasty ring with neighboring ring sizes. This comparison option is particularly advantageous during the learning phase for users who are not yet experienced. By replacing the conventional measuring template sets with a universal measuring template, manufacturing costs and packaging effort can be reduced. In addition, confusion when assembling the measuring template sets is avoided.
