    摘要: Apparatus and methods are disclosed for accessing the interior of an intervertebral disc to perform a function within the disc. The apparatus comprises a catheter having a lumen; and a guide wire having a distal portion and a proximal portion, and configured to be positioned within and moved relative to the lumen of the catheter; wherein the guide wire is capable of navigating itself within an intradiscal section of the intervertebral to a selected section of the disc and the catheter is capable of being advanced relative to the guide wire such that the catheter follows a path of the guide wire within the intradiscal section of the disc to the selected section. These apparatus and methods may be used for the treatment of intervertebral disc disorders such as sealing fissures of the annulus fibrosus, which may or may not be accompanied with contained or escaped extrusions. These apparatus and methods may also be used for the removal or addition of material to the intervertebral disc.

    摘要: A catheter system for use in bypassing a block in an artery comprises four components. These components are an arterial catheter, an intravenous ultrasound catheter, a guide wire system, and finally a covered stent used as graft. The bypassing of the block in the artery which extends along a vein comprises the steps of forming a first connection between said artery and said vein proximal to the block in the artery, forming a second connection between said artery and said vein distal to the block in the artery, introducing a covered stent through said artery proximal to the block therein, through said first connection into said vein, via said vein to and through said second connection, and into said artery distal to the block therein, such that a proximal end of the covered stent is positioned in the artery proximal to the block therein and a distal end of the covered stent is positioned in the artery distal to the block therein, and fixing the proximal and distal ends of the covered stent within the artery.

    摘要: Broche de guidage et ensemble (10) la contenant pouvant s'introduire dans un vaisseau sanguin afin de pénétrer une occlusion dans celui-ci. La broche de guidage comporte une section de fil souple (12) traversée sur toute sa longueur par une lumière concentrique (14), et un élément terminal distal (20) possédant une extrémité arquée (22) et ayant un diamètre plus grand que celui de la partie du fil qui lui est immédiatement contiguë. Ledit ensemble comprend la broche de guidage décrite ci-dessus ainsi qu'une sonde souple (32), dont la longueur est sensiblement égale à celle du fil souple, disposée à l'intérieur de la lumière dudit fil. Lors de la mise en oeuvre, l'élément terminal distal est introduit dans le vaisseau sanguin et vient au contact d'une occlusion. Ensuite, ledit élément terminal heurte l'occlusion à plusieurs reprises jusqu'à ce qu'il la pénètre.
