Definitions
- the present invention relates to a delivery assembly for a cardiac, aortic or arterial implant.
- cardiac or aortic implant is meant here and in the context of the invention, a prosthetic aortic or cardiac valve for replacing a native valve.
- a preferred application is the replacement of a cardiac valve percutaneously, comprising a valve delivery catheter and optionally an introducer, commonly called “introducer”.
- TAVI Transcatheter Aortic Valve Replacement
- the assembly according to the invention can equally well be applied for the replacement of another valve of the heart, such as the triscupid valve or the mitral valve.
- anarterial implant is meant here and in the context of the invention, a prosthetic device which can be a support (balloon, stent) intended to be implanted in an artery of a human being to repair (dilate, repair) open) a damaged artery.
- a prosthetic device which can be a support (balloon, stent) intended to be implanted in an artery of a human being to repair (dilate, repair) open) a damaged artery.
- the invention is applicable to all types of peripheral vascular interventions, on the peripheral arteries, such as carotid arteries, aortas, including the thoracic aortic stent delivery operations (TEVAR acronym for "Thoracic Endovascular”).
- TEVAR thoracic aortic stent delivery operations
- Aortic Repair carotid stents for people suffering from a narrowing of these arteries
- CAS acronym for Carotid Artery Stenting
- These may be cardiac or peripheral pediatric procedures, particularly in the case of congenital heart disease.
- the present invention relates more particularly to the improvement of cardiac pacemaker implantation assistance by means of a pacemaker in order to stabilize, secure and optimize the placement accuracy of the various devices such as stents, balloons or other prostheses.
- the introducer and / or the delivery catheter of the assembly according to the invention can be implanted percutaneously in a patient, and more specifically, trans-femoral, trans-aortic way. carotid or subclavian, or in peripheral arteries such as radial or ulnar arteries.
- a widely known cardiac disease is that related to the calcification narrowing of the cardiac aortic valve, the latter being the valve that separates a cardiac cavity, namely the left ventricle of the aorta and which allows in the open position to let the blood pass through. heart to the rest of the body of a human being.
- a tight or very tight narrowing prevents the aortic valve from opening normally and therefore generates the disease also known as calcified aortic stenosis.
- Treatment for this condition involves replacing the defective heart aortic valve.
- Replacement of a defective cardiac aortic valve is most commonly performed by opening the chest, placing the patient under cardiopulmonary bypass, temporary cardiac arrest, and opening the heart, for excision and replacement of the native valve by an artificial valve or prosthesis.
- one approach has been the establishment of artificial aortic valves, called percutaneous, which is inspired by the techniques of endovascular treatment by introduction of a catheter inside a blood vessel, such as the aorta.
- trans-femoral that is to say by introduction from the femoral artery to the heart or trans-apical, or trans-aortic, or carotid or subclavian, that is to say any path not requiring open-heart surgery through an opening of the chest or extracorporeal circulation.
- the operation itself consists in depositing an artificial valve (prosthesis), which reproduces the general form of a normal native aortic valve, at the calcified native aortic valve (diseased), the latter being left in place and crushed by the prosthesis.
- prosthesis which reproduces the general form of a normal native aortic valve
- calcified native aortic valve diseased
- the artificial valve made in pericardium a thin membrane surrounding the heart, of porcine or bovine origin, is fixed beforehand inside a tubular metallic mesh expandable radially ("stent" in English) and constituted by assembly wire made of shape memory material, for example nickel-titanium alloy or cobalt-chromium, 316L stainless steel for coronary stents.
- shape memory material for example nickel-titanium alloy or cobalt-chromium, 316L stainless steel for coronary stents.
- valve-mesh assembly is compressed at the end of a tubular sheath, called delivery catheter, which can be introduced either directly into an artery, or to inside an introducer allowing access to the artery while maintaining hemostasis.
- delivery catheter a tubular sheath
- valve-mesh assembly is then deposited at the level of the sick valve by dilation of a balloon before placement.
- valve delivery catheters comprising a valve-grill assembly without balloon in which the valve is self-expanding which allows a deposit of the valve which expands radially by simply removing the sheath which surrounds it and therefore without have to dilate a balloon beforehand.
- This temporary heart failure also commonly known as “cardiac stun”
- cardiac stun consists in deliberately beating the heart at 150 to 200 beats per minute so that there is no more effective contraction, which causes a drop in pressure and simulates ventricular tachycardia or fibrillation and therefore stabilization of the heart.
- This stabilization of the core allows the stabilization of the balloon and thus increase the accuracy of the installation of the artificial valve in a few seconds.
- bipolar stimulation catheters with two electrodes, called training probes or electro-systolic stimulation, for the temporary endocardial stimulation of the right ventricle.
- this probe is relatively rigid, and therefore its placement in the right ventricle which is fragile and whose wall is thinner than that of the left ventricle, induces a consequent risk of the phenomenon well known to interventionist physicians under the term "Tamponade", which represents a significant circulatory insufficiency that can even lead to the patient's mortality.
- a stimulation probe is not fixed in a wall of the heart and can therefore move and thus cause a loss of capture of the electrical stimulation signal.
- the heart is then no longer stimulated and therefore has significant movements that hinder the placement of the valve or the balloon.
- an interventionist physician considers as significant the additional operating time associated with the establishment of a temporary stimulation probe, which is an operation not always easy to perform.
- the publication [2] highlights the advantages of achieving this ventricular pacing on the left ventricle and not on the right ventricle and not doing so by means of a specific transvenous stimulation catheter, but by implementing an external pacemaker with the wire guide used for procedures of this type.
- the recommended implementation described in this publication [2] is to use the wire guide supporting the expansion balloon of the stent and introduced into the left ventricle, as a portion connected to the cathode a pacemaker and a cutaneous electrode or needle implanted in the subcutaneous tissue, as a support for the anode of the pacemaker.
- the publications [3] and [4] validate in the case of a coronary angioplasty intervention on a pig population, the effectiveness of a temporary cardiac stimulation with a lower stimulation electrical voltage, by the implementation of the supporting wire guide.
- the stent expansion balloon as part connected to the cathode of a pacemaker and a cutaneous electrode or needle implanted in the subcutaneous tissue, as a support for the anode of the pacemaker.
- these recommended implementations have the advantages of avoiding having to implant a dedicated additional catheter, to avoid additional access to the heart, to reduce the time and cost of the operation, but also to reduce the rate. complications related to the implantation of the dedicated catheter, while allowing stimulation as effective as through a transvenous stimulation.
- the wire guide used for this technique is very stable and comes in permanent support against the wall of the left ventricle relatively thick since it serves as a rail for advancing the stent-balloon-valve assembly through the valve.
