Abstract
A foreign body retrieval device is disclosed. The device moves between an open position for receiving the foreign body and a closed position for capturing the foreign body. A novel method for retrieving a foreign body such as a stent is also disclosed.
Claims20
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.

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.
