摘要:
An expandable medical balloon (10), comprising a balloon, the balloon comprising a cone portion (14A, 14B), a waist portion (16A, 16B) and a body portion (12) and a fiber braid (20) disposed along the cone portion, the waist portion and the body portion of the balloon, the fiber braid comprising a first fiber (21) and a second fiber (22) that is different than the first fiber, the first fiber comprising a polymer material having a first melting temperature and the second fiber is a non-melting fiber.
摘要:
A balloon for a medical device is made from a biocompatible material including a base resin polymer and at least one additive totaling 1.0% or less by weight of the base resin polymer.
摘要:
A segmental crimper comprises at least three crimper segments and an actuator. The crimper segments are arranged circumferentially about a crimper axis that defines axial and radial directions. The crimper segments are movable relative to each other in a manner such that the crimper segments collectively define a variable size aperture that is aligned with the crimper axis. Each of the crimper segments comprises a radio frequency heating element. The actuator is operatively connected to the crimper segments in a manner such that movement of the actuator causes all of the crimper segments to simultaneously move relative to each other and alters the size of the aperture.

A balloon catheter is provided that may be used to dilate hardened regions of a stenosis. The balloon catheter is provided with one or more dilation elements (130, 320) that extend along a surface of a balloon (140, 311). Each dilation element (130, 320) is connected to an outer surface (140, 311) of the balloon by a connector (120, 330). The connector (120, 330) is sufficiently sized and designed to undergo stress-induced plastic deformation incurred during blow molding so that a significant portion of each of the dilation elements (130, 320) does not become absorbed into the wall of the final blow molded balloon (150), thereby maintaining the structural integrity of each of the dilation elements (130, 320).
摘要:
A catheter having shaft segments which are joined together by a strong bond providing a low profile shaft section with a flexibility transition and/or a compositional transition. A balloon catheter embodying features of the invention has a distal tip member (19) and a coupling band member (21) surrounding a junction of an inner tubular member (18) of the shaft (11), and has a gradual change in bending stiffness along a distal end section of the shaft which extends distally from a location within the balloon interior. Another catheter embodying features of the invention has shaft segments joined together by a diagonal seam (120).
摘要:
A medical device comprising a support member adjacent to a first member and a second member, the first and second members may be laser welded to one another by directing radiation absorbable by the first and second members at the first and second members. The support member is provided adjacent to the first member and is constructed and arranged to substantially reflect or substantially transmit radiation at one or more frequencies absorbable by at least one of the first member and the second member.
