    摘要： A guide wire formed with a distal tapered segment and having a distal-end coil carried over a portion of the tapered segment. The strand forming the helical wrappings of the coil is reduced in thickness in the region of proximal attachment to the wire, to reduce the difference in diameter between the wire and the coil. Also disclosed is a method of producing the coil.

    摘要： The self-expandable endovascular apparatus for aneurysm occlusion of the invention comprises a deformable shape memory frame with at least a partial segment covering comprised of a matrix implant material. The device can be folded and/or stretched to adopt a narrow profile for loading into a coaxial delivery device and expands in place as it adopts its original shape on release from the device into an aneurysm. A method of treating an aneurysm, comprises the steps of: (a) providing the self-expandable endovascular apparatus inserted into a lumen of a delivery device comprising a proximal end and a distal end, the distal end having a distal tip; (b) advancing the distal tip of the delivery device into an opening in an aneurysm having an interior sac; (c) advancing the apparatus through the lumen into the opening; and (d) withdrawing the delivery device, whereby the apparatus expands into the sac and covers the opening.

    摘要： An artery, vein, aneurysms vascular malformation or arterial fistula is occluded through endovascular occlusion by the endovascular insertion of a platinum wire and/or tip into the vascular cavity. The vascular cavity is packed with the tip to obstruct blood flow or access of blood in the cavity such that the blood clots in the cavity and an occlusion if formed. The tip may be elongate and flexible so that it packs the cavity by being folded upon itself a multiple number of times, or may pack the cavity by virtue of a filamentary or fuzzy structure of the tip. The tip is then separated from the wire mechanically or by electrolytic separation of the tip from the wire. The wire and the microcatheter are thereafter removed leaving the tip embedded in the thrombus formed within the vascular cavity. Movement of wire in the microcatheter is more easily tracked by providing a radioopaque proximal marker on the microcatheter and a corresponding indicator marker on the wire. Electrothrombosis is facilitate by placing the ground electrode on the distal end of the microcatheter and flowing current between the microcatheter electrode and the tip.REEAXMINATION RESULTS The questions raised in reexamination request 90/007,231, filed Oct. 4, 2004 have been considered and the results thereof are reflected in this reissue patent which constitutes the reexamination certificate required by 35 U.S.C. 307 as provided in 37 CFR 1.570(e), for ex parte reexaminations, or the reexamination certificate required by 35 U.S.C. 316 as provided in 37 CFR 1.99(e) for inter partes reexaminations.

    摘要： The invention is surgical instruments which facilitate substantially linear incisions, especially through the wall of vessels, such as arteries, which have been specifically designed for coronary artery bypass graft procedures (CABG) on the beating heart. The instruments of the invention are particularly useful to create the incision in the artery to which the bypass graft is sewed, typically the left anterior descending artery (LAD). The instruments of the invention allow incisions to be rapidly made, precisely measured, and cleanly formed so that a bypass graft can be rapidly sewn in place. In one embodiment, the invention is comprised of a hand-held instrument with a curved cutting edge formed on the interior edge of a curved or arcuitous segment located near the end of the instrument. The tip of the instrument has a point of penetrating the vessel wall. The point may have several alternate shapes to facilitate penetration of the vessel wall while maximizing the trauma to the surrounding tissue. Another embodiment is comprised of a hand-held instrument with moveable member such that the incision is created by engaging a cutting blade against a stop with the tissue being cut therebetween. This instrument is also constructed to facilitate a rapid linear incisions in a vessel while minimizing the possibility for damage to the surrounding tissue. In another embodiment, the instrument features a motion-cancelling member which compensates for the movement of the target surface to be incised. This embodiment has a cutting blade which is manipulated form handle which is isolated from the movement of the tissue containing or proximate to the target of the incision. The instruments facilitate the invasive cardiac procedures by creating linear incisions quickly without undue trauma to surrounding tissue and without excess loss of blood.
