VASCULAR OCCLUSION DRILL
First Claim
1. A medical device for treatment of an obstructed vessel, said apparatus comprising:
- (a) an external conduit comprising a proximal end, a distal end, a cylindrical outer surface sized for passage through a blood vessel, and an internal lumen, said conduit lumen being threaded within at least a portion of the length of said conduit at said distal end, and(b) a shaft comprising a proximal end, a distal end, an internal lumen, and a cylindrical outer surface fitted inside the conduit lumen and having external threading over at least a portion of the length of said shaft at said distal end;
wherein said shaft threading engages said external conduit threading allowing said shaft to be advanced through said lumen by rotation of said shaft.
