Method and apparatus for the guided bypass of coronary occlusions

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