Abstract:
1. Apparatus for removing emboli from a vessel during an interventional procedure, the apparatus comprising: a catheter having proximal and distal ends, a working lumen extending therethrough; to define an interior surface, and an exterior surface; and an occlusion balloon having a distal end affixed to the exterior surface of the catheter adjacent the distal end of the catheter and a proximal end everted to surround, and affixed to, the exterior surface of the catheter at a location proximal of the distal end of the catheter, the occlusion balloon having a contracted state suitable for insertion into a vessel and a deployed state configured to occlude antegrade flow in the vessel, the occlusion balloon having a substantially rhomboidal shape in the deployed state, wherein the occlusion balloon consists of a single sheet of elastomeric having a substantially uniform wall thickness, and in the deployed state, provides a funnel-shaped surface that extends beyond the distal end of the catheter, a portion of the distal end of the occlusion element also affixed to the interior surface of the catheter to provide a seamless transition into the working lumen.
