Balloon systems for treating bifurcated lumens include desirable burst and folding characteristics. In some cases, the balloon systems can be formed by varying the wall thickness of a balloon parison.

Balloon bifurcated lumen treatment

A medical device for insertion and expansion within a bifurcated lumen is described. An expansion region of the device has regions thereon which, in some cases, enable the device to fold into a predetermined configuration upon deflation. The regions may be defined by differing modulus of the device material.

Deflatable bifurcated device

The present invention is directed to distal tip designs for catheter, wherein distal tip material is positioned about an inner shaft. The distal tip material may also be used as a tie layer for thermally bonding two incompatible materials together, such as a waist portion of a balloon to the inner shaft.

Balloon catheter tip design

Medical device balloons are formed from a tubular parison by a process or apparatus which establishes a controlled location (initiation zone) on the parison where radial expansion is initiated. Initiation within the initiation zone is achieved by heating the parison in that location to a higher temperature than the remainder of the parison for at least a portion of the blowing time. A variety of apparatus configurations are provided, some of which allow for the size and location of the initiation zone to be readily reconfigured. Balloons can also be modified, post-blowing, using heating apparatus and methods described.

Process and apparatus for forming medical device balloons

A balloon catheter comprises a balloon, an inner shaft, an outer shaft and a transition shaft. The transition shaft has a proximal portion and a distal portion joined by a tapered portion. The proximal portion has a diameter greater than the distal portion. The proximal portion has a first end portion engaged to at least a portion of the outer shaft at a first engagement site. At least a portion of the proximal waist is engaged to the proximal portion of the transition shaft at a second engagement site. At least a portion of the end region of the inner shaft is engaged to the distal portion of the transition shaft at a third engagement site. The distal portion extends through the balloon wherein at least a portion of the distal waist of the balloon is engaged to the distal portion of the transition shaft at a forth engagement site.

Catheter support

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.
