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.

A non-deployable stent adapted to be secured to an angioplasty balloon catheter comprising:
- a proximal end;
- a distal end;
- at least one extension section, at least one set of serpentine rings and at least one set of elongation links connecting the proximal end to the distal end, to allow expansion of the stent to accommodate the inflation of the balloon;
- and
- the stent being made of a material having a memory so that the stent collapses upon deflation of the balloon.
An angioplasty balloon catheter comprising:
- an inflatable/deflatable balloon having a proximal end and a distal end;
- and
- a non-deployable stent adapted to be secured to the balloon comprising a proximal end;
- a distal end;
- an extension section on said proximal end and an extension section on said distal end;
- at least two sets of serpentine rings, with a set of elongation links located between said sets of serpentine rings, between said expansion sets, said extension sections, said sets of serpentine rings and said set of elongation links allow expansion of the stent to accommodate the inflation of the balloon;
- and the stent being made of a material having a memory so that the stent collapses upon deflation of the balloon.
