Abstract
The invention being disclosed describes a medical device for removal of a thrombus or clot in a vascular setting by using a rotational, expandable basket structure in combination with drug infusion, blood/particle aspiration and clot isolation by distal and proximal occlusion.
Claims20
A catheter for blockage removal for a circulatory system, comprising:
- a main tubular shaft comprising a distal tip and a control handle coupled to the proximal end of the main tubular shaft;
- an isolation element coupled to the main tubular shaft, the isolation element comprising a first expandable isolation member and a second expandable isolation member;
- and
- a rotational member coupled to the main tubular shaft, the rotational member comprising a bi-modal expandable macerating element,
- wherein the rotational member is disposed between the first expandable isolation member and the second expandable isolation member, such that the diameter and speed of the rotational member is adjustable during removal of a blockage in the circulatory system.

A method for removing a blockage, comprising:
- inserting a catheter into a patient's circulatory system, wherein the catheter comprises a first expandable isolation member, a second expandable isolation member and a rotational member, wherein the rotational member includes an expandable macerating element;
- expanding the first expandable isolation member and the second expandable isolation member;
- expanding the expandable macerating element;
- and
- rotating the expandable macerating element at least 500 rpms to macerate a clot,
- wherein the rotational member diameter is expandable independent of rotational speed.
