Definitions

  • This invention relates generally to the area of medical devices. More specifically, this invention relates to devices known as guidewires.
  • Guidewires are medical devices used in numerous medical procedures. More specifically, guidewires are usually used to navigate the vasculature of the human body prior to, or in conjunction with, the placement of a separate medical device, e.g., a catheter, to perform a therapeutic or diagnostic procedure.
  • the present invention provides an improved guidewire having an S-shape portion.
  • the present invention comprises an S-shaped guidewire.
  • the invention comprises a flexible guidewire comprising proximal, medial and distal segments.
  • the guidewire also contains an S- shape portion.
  • the S-shape portion contains at least three rounded curves. The first and third curve of the S-shape portion bend outward in a direction opposite from the bend in the second curve.
  • the flexible S-shaped wire portion will retain it's "S" shape in the body, but under direct manipulation, the flexible wire can be positioned into other curved shapes.
  • the S-shape portion is located at or near the distal segment of the guidewire.
  • the distal end of the S-shape can also contain an atraumatic tip.
  • the guidewire comprises a core wire having proximal, medial and distal segments, an S-shaped portion, a primary wire coil, an outer secondary coil and an inner secondary coil.
  • FIG. 1 shows a side view of one embodiment of the guidewire of the present invention
  • FIG. 2 shows a partial side view of one embodiment of the guidewire of the present invention.
  • FIG. 3 shows a partial side view of a part of the S-shape portion of the guidewire of the present invention.
  • FIG. 4 shows a partial side view of a part of the S-shape portion of the guidewire of the present invention.
  • top,” “bottom,” “side,” “inner,” “outer,” “interior” and “exterior” and the like are only used to describe elements as they relate to one another, but are in no way meant to recite specific orientations of the apparatus, to indicate or imply necessary or required orientations of the apparatus, or to specify how the invention described herein will be used, mounted, attached, or positioned in use.
  • the present invention is drawn to an S-shaped guidewire.
  • the S-shape in the guidewire allows for the guidewire to advance around sharp corners in the body.
  • the curved portions of the S-shaped guidewire allows for the pushing force used when positioning the guidewire to not just be transmitted directly to the end tip of the guidewire.
  • the curved S-shaped portion of the guidewire can act as a spring and absorb part of the pushing force of the guidewire as well as help redirect the end tip of the guidewire. This design allows for the curves of guidewire to push off the back side of a vessel and allow the end tip of the guidewire to enter into a side branch vessel with greater ease.
  • FIG.' s 1-4 show the guidewire 10 of the present invention.
  • the guidewire
  • the guidewire 10 can be crafted to a diameter selected by one skilled in the art.
  • One suitably diameter for coronary procedures is around .014".
  • the guidewire 10 has a solid core wire 12 which extends the entire length of guidewire 10.
  • the core wire 12 has a proximal segment 14, a medial segment 15 and a distal segment 16.
  • the diameter of the core guidewire decreases from the proximal 14 to the distal 16 segment.
  • the core wire 12 suitably is comprised of solid metal, most suitably stainless steel or other similar metal or alloy suitable for use in the human body.
  • a flexible S-shape portion 22 is suitably positioned on the core wire 12.
  • the S-shape portion 22 is suitably constructed from a metal wire suitable for use in a human body.
  • the S-shape portion 22 has a first curve 40, a second curve 42 and a third curve 44.
  • the first 40 and third 44 curve of the S-shape portion bend outward in a direction opposite from the bend in the second curve 42.
  • the flexible S-Shape portion 22 will retain it's "S" shape in the body, but under direct manipulation, the flexible wire can be positioned into other curved shapes.
  • the S-shape wire portion 22 is at least one inch in length.
  • the S-shape portion 22 is connected to the distal segment 16 of the core wire 12.
  • the S-shape portion 22 can either be attached or integral to core wire 22.
  • the S-shaped wire portion 22 can terminate in any number of suitable designs. In one design (FIG. 3) the S-shape portion 22 terminates in a J bend 50, in another design (FIG. 4) the S-shape portion terminates in straight lead 52 with an atraumatic tip 34.
  • the atraumatic tip 34 can be made from any material suitable for use in the human body. In another embodiment the S-shape portion 22 terminates with an atraumatic tip 34 (FIG. 1 and 2)
  • the guidewire 10 can further include a flexible primary wire coil 38 attached to the core wire at its proximal segment 14.
  • the primary wire coil 38 runs to the distal segment 16 of the core wire 12.
  • the primary wire coil is connected to at least portions of the proximal 14 or medial 15 segments of the core wire 12.
  • An outer secondary flexible wire coil 24 and an inner secondary flexible wire coil 26 extend the length of the flexible S-shaped wire portion 22.
  • the outer 24 and inner 26 secondary coil wires are at attached to at least a portion of the core wire 22 or S-shape potion 22.
  • the primary wire coil 38 and secondary wire coils 24 and 26 can suitably be made from any metal suitable for use in the human body. More suitably the primary wire coil 38 and the outer secondary wire coil 24 can be made from stainless steel, and the inner secondary wire coil 26 can be made from platinum.

Abstract

L'invention concerne un fil-guide comprenant des segments proximal, médial et distal et une partie en S. La forme en S du fil-guide permet à celui-ci d'avancer autour des coins étroits du corps. La partie en S courbée du fil-guide peut agir comme un ressort et absorber la partie de la force de poussée du fil-guide, ainsi qu'aider à rediriger l'embout d'extrémité du fil-guide. Cette configuration permet aux courbes du fil-guide de pousser le côté arrière d'un vaisseau et elle permet à l'embout d'extrémité du fil-guide d'entrer dans un vaisseau de ramification latéral avec une grande facilité.
