MEDICAL RETRIEVAL DEVICES AND METHODS

摘要

A medical device includes a sheath having a lumen and an elongate member disposed within the lumen of the sheath. The elongate member is moveable relative to the sheath and includes a retrieval assembly. The retrieval assembly has a collapsed position within the lumen of the sheath and an expanded position when extended beyond a distal end of the sheath. The elongate member defines a lumen configured to receive a laser.
