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.
Claims20
A balloon catheter comprising:
- a catheter shaft;
- a balloon on the catheter shaft;
- and
- a constraining structure disposed over the balloon, the constraining structure fixedly attached to the catheter shaft distal of the balloon and/or proximal of the balloon to prevent detachment of the constraining structure from the catheter shaft, the constraining structure comprising a plurality of openings;
- wherein the constraining structure is configured to transition between an unexpanded configuration and an expanded configuration;
- wherein inflation of the balloon expands the constraining structure to the expanded configuration with a plurality of isolated balloon regions protruding from the plurality of openings, the plurality of isolated balloon regions configured to contact a wall of a blood vessel with the constraining structure displaced from the wall of the blood vessel.
