METHOD AND APPARATUS FOR ALLOWING BLOOD FLOW THROUGH AN OCCLUDED VESSEL
First Claim
1. A device for retrieving at least a portion of an occlusion from a small blood vessel of 5 mm or less inner diameter, comprising:
- a first section comprising a tubular body deliverable into and across said occlusion, said tubular body expandable within said occlusion, said tubular body defining a distal end and a proximal end;
said tubular body comprising braided filaments;
a second member section extending from said proximal end of said tubular body and comprising filaments interweaved in said braided filaments of said tubular body, wherein said second member section is configured to be tensioned so as to reduce a diameter of said tubular body.

Abstract
A device arranged to sustain and/or provide at least partial patency of a small blood vessel exhibiting an occlusion, the device constituted of a tubular body expandable from a first small diameter state for manipulation to, and through, the occlusion of the small blood vessel and a second large diameter state, the inner dimensions of the second large diameter state being no more than 50% of the diameter of the small blood vessel at the occlusion location, the device presenting a conduit for blood flow through the occlusion when in the large diameter state. In one embodiment the small blood vessel is an intracranial blood vessel.
