Abstract
Systems and methods can involve wedge dissectors attached to strips in turn attached to medical balloons, for forming serrations within vascular wall tissue for angioplasty as well reducing vessel recoil, reducing residual stenosis, and increasing volumetric blood flow post angioplasty. The design, methods of use, intended outcomes, and process to build this type of balloon is described herein.
Claims21
(canceled)
An intravascular device comprising:
- a catheter comprising a balloon and a plurality of strips disposed on an outer surface of the balloon, each strip of the plurality of strips including a plurality of wedge dissectors spaced apart along a surface of each strip;
- and
- a plurality of pumps connected to the balloon and acting on a liquid medium used to fill the balloon, wherein a pump of the plurality of pumps is configured to produce hydraulic waves for calcium fracturing,
- wherein the plurality of wedge dissectors is configured to alter a vessel wall by creating linear serration lines in plaque.

An intravascular device comprising:
- a catheter comprising a balloon and a plurality of strips disposed on an outer surface of the balloon, each strip of the plurality of strips including a plurality of wedge dissectors spaced apart along a surface of each strip;
- and
- a plurality of pumps connected to the balloon and acting on a liquid medium used to fill the balloon, wherein a pump of the plurality of pumps is configured to produce hydraulic waves for calcium fracturing,
- wherein the plurality of wedge dissectors is configured to cause prick points along an internal elastic lamina of a vessel which allow the internal elastic lamina to tear along serrated lines of weakness under pressure.
