Particle-removing medical device and method
First Claim
Patent Images
1. A method for acting on plaque within a vascular conduit of a body for treatment of cardiovascular disease comprising:
- obtaining a removable therapy device comprising a radially-expandable element within a multi-stranded tubular braid;
positioning the removable therapy device at a target site within the vascular conduit of the body;
expanding the tubular braid against the plaque by the radially-expandable element within the tubular braid causing the tubular braid to make intimate contact with the plaque;
creating micro-fractures within the plaque;
contracting the removable therapy device; and
removing the removable therapy device from the body.

Abstract
A particle-removing medical device includes an outer, hollow tube having a tube distal end and a porous braided structure having a distal part and a proximal part. Structure, housed within the tube and having a distal end positioned distally of the tube distal end, is used to move the braided structure from a contracted condition to an expanded condition by moving the distal ends of the tube and the structure towards one another. The braided structure is constructed to inhibit particles from moving completely through the braided structure when in the expanded condition.

7. A method for acting on plaque within a vascular conduit of a body for treatment of cardiovascular disease comprising:
-
obtaining a removable therapy device comprising a radially-expandable balloon within a multi-stranded tubular braid, the multi-stranded tubular braid having a contact-dispensable agent in contact therewith; the obtaining step further comprising; selecting a multi-stranded tubular braid; selecting the agent; and applying the agent to the multi-stranded tubular braid; positioning the removable therapy device at a target site within the vascular conduit of the body; expanding the tubular braid against the plaque by the radially-expandable balloon within the tubular braid causing the tubular braid to make intimate contact with the plaque; creating micro-fractures within the plaque; dispensing the agent from the tubular braid into the micro-fractures within the plaque; contracting the removable therapy device; and removing the removable therapy device from the body.
