Abstract: A medical retrieval tool including a sheath; and a basket device connected to the sheath. The basket device includes a shaft and a basket located at a distal end of the shaft. The shaft is movably located in the sheath. The basket includes a first basket cage section and a second basket cage section. The first basket cage section is located in front of the second basket cage section. The basket is configured to be extended from a distal end of the sheath in a plurality of deployment modes including a first deployment mode where the first basket cage section is deployed in a first fully expanded shape and the second basket cage section is located in the sheath; and a second deployment mode where both the first basket cage section and the second basket cage section are deployed out of the distal end of the sheath.

Abstract: Forceps that include a hand piece, a jaw assembly connected to the hand piece, and a web. The jaw assembly is moveable between an open position and a closed position. The web is adapted to block an anatomical feature from extending beyond a proximal end of a gripping section of the jaw assembly. The web remains generally stationary relative to the handpiece when the jaw assembly is moved between an open position and a closed position.

Abstract: A forceps includes jaws, a first shaft having a first slot, a second shaft extending along the first shaft and having a second slot, and a rod that extends along the second shaft. The rod has a third slot including a locking portion and a guide track portion. A pin extends through the first slot, the second slot, and the third slot to prevent deployment of the rod when the pin is in the locking portion and to permit deployment of the rod when the pin is in the guide track portion. A first actuator produces relative movement of the first and second shafts to move the jaws relative to each other and move the pin from the locking portion to the guide track portion of the third slot. A second actuator produces movement of the rod to deploy the rod when the pin is in the guide track portion.

Abstract: A surgical device that includes a first support member extending along a longitudinal axis; a bladder located on the first support member; a first sealing member located on the bladder; and a second sealing member located on the bladder. The sealing member is located on one side of the longitudinal axis; and the second sealing member is located on another side of the longitudinal axis. The bladder is inflatable, and inflating the bladder changes a position of the first sealing member, the second sealing member, or both relative to the first support member.
