Abstract
A retrieval catheter (10) for removing deleterious materials (S) from body lumens has an elongate catheter body (12) having a slack net (26) at its distal end (16). The slack net may be collapsed to facilitate introduction into the body lumen and opened in situ to permit capture and retrieval of the deleterious materials. A method for removing ureteral stones from the ureter is described.
