Abstract
A catheter assembly including a balloon which incorporates a reverse-cone design for improved stent delivery. The reverse-cone design provides an inflatable area which extends longitudinally over the balloon waist. When folded or deflated, the portions of the balloon extending over the waist in conjunction with the waists provide a bulky mass onto which a stent may be securely crimped without the use of additional structure under the balloon.
Claims5
A catheter balloon comprising:
- an inflatable member having a proximal waist and a distal waist, wherein in use the catheter balloon extends parallel with, and overlaps the waists of the balloon, said waists securely sealing the catheter balloon to a catheter shaft proximate the ends of the catheter balloon;
- a centermost balloon section, a portion of which extends over the waists of the balloon when deflated;
- and
- a proximal and a distal cone section, the cone sections connecting each end of the centermost section of the catheter balloon to the waists of the balloon, wherein the balloon includes a conical angle as defined by the interior angle formed between the centermost section and the cone sections of the catheter balloon when inflated that is 90 degrees or less.
