Balloon catheter with non-deployable stent
First Claim
1. A method for performing angioplasty in a blood vessel, said method comprising:
- introducing a balloon catheter into the blood vessel;
inflating the balloon to radially expand a non-deployable stent, wherein a portion of the stent shortens in length as the stent is radially expanded;
wherein the non-deployable stent is attached to the balloon catheter at at least one location and includes a region which expands longitudinally to compensate for shortening of the length which results from radial expansion.

Abstract
An angioplasty balloon including a non-deployable stent to prevent or reduce the potential for slippage of the inflated balloon with respect to the vessel wall being treated. The balloon includes a non-deployable stent that is adapted to be secured to the balloon or angioplasty balloon catheter. The stent has a proximal end, a distal end, and at least one extension section, at least one set of serpentine rings and at least one set of elongation links that allow expansion of the strut to accommodate the inflation of the balloon. The stent is made of a material so that the stent collapses upon deflation of the balloon.

7. An angioplasty catheter comprising:
-
a catheter shaft having a distal end and a proximal end;
an inflatable balloon disposed near the distal end of the catheter shaft;
a non-deployable stent disposed over the inflatable balloon;
wherein the stent is attached to the shaft on at least one side of the balloon and wherein the stent comprises longitudinally expandable structure which accommodates axial shortening of the stent upon radial expansion of the stent resulting from balloon expansion. - View Dependent Claims (8, 9, 10, 11, 12)
