Patent Images
1. A foreign body retrieval apparatus comprising:
- a handle, an axially elongate member having a foreign body capturing assembly, the elongate member having an inner lumen that is sized and shaped to receive a viewing apparatus;
a substantially tubular member having a distal end and an inner lumen that is sized and shaped to receive the elongate member;
the handle, elongate member and tubular member being operatively associated to move between an open position with the foreign body capturing assembly adapted to receive a foreign body, and a closed position with the foreign body capturing assembly adapted to control a foreign body, and a sheath having an inner lumen that is sized and shaped to afford sliding passage of the tubular member and the elongate member while in the closed position.

15. A method of removing an in vivo stent comprising the steps of:
-
providing an assembly comprising a handle, and an axially elongate member having a stent capturing member, receiving at least a portion of the elongate member within a substantially tubular member, inserting a viewing apparatus into an inner lumen of the elongate member;
receiving a portion of the tubular member within a sheath having a distal end;
inserting the sheath into a tubular passage of a patient, viewing the in vivo stent;
moving the stent capturing member toward an open position with the handle, engaging the stent with the stent capturing member, then moving the stent capturing member toward a closed position, and causing relative axially movement between i) the tubular member and elongate member with the engaged stent, and ii) distal end of the sheath to slide the stent from the patient.
