摘要： Improved apparatus and methods are described for performing endarterectomy remotely via intraluminal techniques. A flexible blade dissector has a curved, diamond-shaped flexible dissecting blade mounted on a catheter shaft. The distal edge of the flexible dissecting blade is configured to form a dissecting edge for separating an atheromatous plaque from the medial layer of an artery wall. The flexible blade dissector may incorporate a steering mechanism to direct the flexible dissecting blade along a preferred path within the arterial wall. The endarterectomy method is performed by making an incision into an artery wall and initiating a plane of separation between an atherosclerotic plaque and the medial layer of the artery wall, inserting the flexible blade dissector into the plane of separation and advancing the flexible dissecting blade to longitudinally extend the plane of separation. Optionally, a second flexible blade dissector with a wider dissecting blade may be inserted coaxially over the catheter shaft of the first flexible blade dissector and advanced to laterally expand the plane of separation. Once the plaque has been freed from the entire inner circumference of the arterial lumen, the plane of separation is terminated on the distal and proximal ends, and the plaque is removed from the arterial lumen.

摘要： An improved intraluminal grafting system incorporating novel structural features for enhancing the effective and efficient deployment of a bifurcated prosthesis having a plurality of attachment systems, in the vessel of an animal body, the system including a balloon catheter assembly, an ipsilateral capsule catheter assembly, distal and contralateral capsule assemblies and means interacting therewith, and a capsule jacket assembly. The capsule assemblies include an ipsilateral capsule assembly, a contralateral capsule assembly and a distal capsule assembly, wherein the attachment systems of the bifurcated prosthesis are disposed within the three capsule assemblies. The capsule jacket assembly includes a removable sheath that covers the bifurcated prosthesis and capsule assemblies to provide a smooth transition along the length of the deployment catheters. The bifurcated prosthesis is comprised of a main tubular member and two tubular legs, having attachment systems secured to the superior end of the main tubular member and the inferior ends of the tubular legs. An inflatable membrane configured on the balloon catheter is used to firmly implant the attachment systems within the vessel. The bifurcated prosthesis and attachment systems are configured to remain in the vessel after the deployment catheters are withdrawn. A novel method of use of the present intraluminal grafting system is also disclosed, for example, for deploying a bifurcated prosthesis proximate the abdominal aortic bifurcation.
