摘要： A cannula assembly having a retention member and a method of manufacture of the cannula assembly is provided. The cannula assembly includes a cannula and a sleeve disposed around the cannula from a proximal end to a distal end. The sleeve can include a balloon formed by a stretch blow molding process following local heating once advanced over the cannula. Once formed, the balloon can be conditioned to constrict against the cannula. A conditioning aid can be advanced over the balloon when it is still formable to constrict the balloon against the cannula.

摘要： Described herein are systems and methods from delivering prosthetic devices, such as prosthetic heart valves, through the body and into the heart for implantation therein. The prosthetic devices delivered with the delivery systems disclosed herein are, for example, radially expandable from a radially compressed state mounted on the delivery system to a radially expanded state for implantation using an inflatable balloon of the delivery system. Exemplary delivery routes through the body and into the heart include transfemoral routes, transapical routes, and transaortic routes, among others.

摘要： A multi-stage balloon catheter (20) has a deflated state, a first inflation state at a first pressure and a second inflation state at a higher fluid pressure. In the first inflation state, the multi-stage balloon has a plurality of bulb segments (42) separated by waist hoops (40) that allow the multi-stage balloon to conform to match the curvature of a passageway. When pressure is increased in the multi-stage balloon from the first inflation state to the second inflation state, the waist locations expand either by breaking or stretching the waist restraints or by overcoming expansion resistance incorporated into the balloon material at the waist locations. The multi-stage balloon catheter may be used to implant a stent (90) in a manner to conform and match a curved passageway rather than tending to straighten the passageway.

摘要： In a catheter (10), a tubularly net-shaped reinforcement member (28) is disposed between an inner layer (24) and an outer layer (26) configuring a balloon (14). The reinforcement member (28) has a first thread (29) formed of a high-strength fiber. Both end portions of the reinforcement member (28) in an axial direction are respectively provided with ring-shaped inflation restriction portions (36) welded to the first thread (29). The inflation restriction portions (36) respectively restrict inflation of both the end portions of the reinforcement member (28) in a circumferential direction.
