## Abstract

An occlusion clearing device for a patient has a housing with a motor(s) that generates repetitive motion, which is reciprocating, rotational or both. A clearing stem including a sheath that has a lumen, wherein aspiration is conducted through the sheath lumen. A wire is located in the sheath lumen and receives repetitive motion from the controller. The sheath terminates in a sheath end having at least one sheath opening. The wire terminates in a wire tip, which may be flat, helical, or tubular. The wire tip is positioned within the sheath end, in proximity to the sheath opening(s), and movement of the wire tip and/or sheath end relative to each other creates shearing forces that break up an adjacent occlusion.

## Claims

### Claim 1

An occlusion clearing device, comprising:
a sheath having a distal end and a proximal end and a lumen extending from said proximal end to said distal end;
a sheath end attached to said distal end of said sheath, said sheath end having at least one sheath opening and a sheath end lumen extending through said sheath end from said sheath opening to said lumen of said sheath;
a wire having a distal end and a proximal end, said wire positioned in said lumen of said sheath;
a wire tip attached to said distal end of said wire and positioned within said sheath end;
at least one motor generating repetitive motion including at least one of reciprocating motion in a longitudinal direction and rotational motion about an axis;
said proximal end of at least one of said sheath and said wire in mechanical communication with said at least one motor and receiving said repetitive motion;
said sheath end and said wire tip collectively creating shearing force during said repetitive motion to break up an occlusion; and
a housing including a receiver housing including a receiver, and a drive housing including said at least one motor and a connector, wherein said receiver housing and said drive housing are selectively attached in mechanical communication of said repetitive motion from said at least one motor to at least one of said sheath and said wire.
