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

Catheter distal tip

A stent retaining sleeve which may be employed with a stent delivery system. The sleeves having two tubular components which are engaged to one another. The first component is an elastomeric tube which is designed to be disposed about the end of a stent and the portion of the catheter immediately adjacent thereto. The first component includes an inner surface which may be at least partially prelubricated with a lubricant. The second sleeve component is a second elastomeric tube which partially overlaps at least a portion of the first tube and is engaged thereto. A second portion of the second tube is constructed and arranged to engage a portion of the catheter shaft immediately adjacent thereto.
