摘要: Described herein is a catheter method and apparatus for the guided intraluminal bypass of a coronary occlusion. A method is described employing an intraluminally operable catheter shaft including an optionally steerable working element, combined with an extraluminally operable locator including an imaging device, to selectively direct the working element to create a fluid path from the artery proximal to the occlusion into the vein and further from the vein back into the artery distal to the occlusion, to perfuse myocardium distal to the occlusion. Methods are described for creating a fluid path from the artery proximal to the occlusion into an adjacent vein and thereafter either stent grafting the fluid path to the vein, directing arterial blood distally within the vein, or stenting the fluid path and occluding the vein proximal thereto, in either case arterializing the venous system distal to the stent or stent graft. A catheter shaft is described for creating and perfusing the fluid path. Conical, guide wire and tissue-penetrating working elements are described. A scanning acoustic transducer and flexible imaging tube, and suction devices for anchoring are described for the locator. A signal-emitting working element and signal-detecting locator cooperating therewith are described.

摘要: A suture applying device comprises a shaft which carries a pair of needles near its distal end. The needles are joined by a length of suture, and the shaft is used to both introduce the needles into a lumen of a body structure and to push the needles back through tissue on either side of the puncture site. After the needles have passed through the tissue, they are captured on the shaft and drawn outward through the tract, leaving a loop of suture behind to close the puncture site near the body lumen. The suture can then be tied and the knot pushed back through the tract to complete the closure. Alternatively, a locking fastener formed of a resorbable material can be placed into the penetration over the sutures and the sutures tied over the fastener.
