APPARATUS AND METHODS FOR REMOVING RELATIVELY LARGE AND SMALL STONES FROM A BODY PASSAGE

摘要

The present invention provides apparatus and methods suitable for removing at least one stone in a body passage. The apparatus comprises a balloon catheter (22) having at least one working lumen (31) adapted to receive an extraction basket (40). In use, the extraction basket may be used to capture and remove relatively large stones, and/or crush relatively large stones into smaller stone fragments. The balloon may then be inflated and maneuvered to engage the stone fragments and urge at least one of the stone fragments out of the body passage.
