Abstract
Abstract Methods and apparatus are provided for removing emboli during an angioplasty, stenting, or surgical procedure comprising apparatus for occluding the external carotid artery to prevent reversal of flow into the internal carotid artery during carotid stenting, the apparatus further comprising a wedge or capsule configured to reduce the risk of potentially dangerous interaction with the stent during retrieval.

Claims Analysis
Total Claims: 27
Claim 1
Independent Claim
204 words
Apparatus for removing emboli during an angioplasty or stenting procedure, the apparatus comprising: a guide wire having proximal and distal ends, and a lumen extending therebetween; an inflation port coupled to the proximal end of the guide wire in communication with the guide wire lumen; an inflatable member disposed on the distal end of the guide wire in communication with the guide wire lumen; means for reducing the risk of puncturing the inflatable member disposed on the guide wire; a catheter having proximal and distal ends, a lumen extending therethrough, and a blood outlet port in communication with the lumen, the catheter adapted to be disposed in a patient's carotid artery, the guide wire and inflatable member configured to pass through the lumen; an occlusion element disposed on the distal end of the catheter and having an opening that communicates with the lumen, the occlusion element having a contracted state suitable for transluminal insertion and an expanded state wherein the occlusion element occludes antegrade flow in the artery; a venous return catheter having proximal and distal ends, a lumen extending therethrough, and a blood inlet port in communication with the lumen; and tubing that couples the blood outlet port to the blood inlet port.
