Abstract
Abstract A stent comprising varying porosity's for use in vessels with bifurcations or side branches. The stent allows for scaffolding of the stenotic area but still allows for flow into the side branches. A distal protection system is also described.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
117 words
A device for the removal of particles from a lumen within the body comprising: an outer, hollow tube having a tube distal end; an inner member housed within the tube and having an inner member distal end positioned distally of the tube distal end; a porous braided structure having a distal part secured to the inner member distal end and a proximal part secured to the tube distal end; the braided structure movable from a contracted condition to an expanded condition by moving at least one of the tube and inner member distal ends towards the other; and the braided structure adapted to inhibit particles from moving completely through the braided structure when in the expanded condition.
Claim 2
Independent Claim
117 words
A device for the removal of particles from a lumen within the body comprising: an outer, hollow tube having a tube distal end; an inner member housed within the tube and having an inner member distal end positioned distally of the tube distal end; a porous braided structure having a distal part secured to the inner member distal end and a proximal part secured to the tube distal end; the braided structure movable from a contracted condition to an expanded condition by moving at least one of the tube and inner member distal ends towards the other; and the braided structure adapted to inhibit particles from moving completely through the braided structure when in the expanded condition.
Claim 3
Dependent Claim
20 words
The device as in claim 1 where said braided structure has a porous proximal side and a porous distal side.
Claim 4
Dependent Claim
17 words
