Abstract
An angioplasty balloon having an elastic constraining structure that partially expands with the balloon so that, at maximum balloon inflation, the constraining structure forms a pattern of channels or “pillows” on the balloon.
Claims23
A system for performing angioplasty, said system comprising:
- a catheter shaft having an inflatable balloon at its distal end;
- a constraining structure disposed over the inflatable balloon, said constraining structure having a non-expanded configuration where it lies closely over the balloon prior to inflation and an expanded configuration which is smaller than an unconstrained size of the balloon so that the structure restrains the balloon inflation along a plurality of crossing channel lines.
A method for treating a lesion in a blood vessel, said method comprising:
- inflating a balloon within the blood vessel;
- and
- constraining the balloon inflation along a plurality of crossing channel lines, wherein a number of isolated protruding regions contact the lesion while the channel lines are recessed from the vessel wall.
A method for treating a non-uniform lesion in a blood vessel, said method comprising:
- inflating a balloon within the lesion, wherein the balloon surface is formed into a plurality of discrete protruding regions which each separately engage a segment of the lesion with a localized force applied by each protruding region to avoid excessive pressure applied against any segment of the lesion.
