Abstract: A stone retrieval device includes a sheath and a stone retrieval basket that includes a distal region with a plurality of basket wires and a proximal region with one or more core wires. The stone retrieval basket is contained within the sheath and is movable out a distal opening of the sheath to cause the plurality of basket wires to open into a basket shape. The stone retrieval device further includes a lock mechanism that locks the position of the stone retrieval basket with respect to the position of the sheath and a basket force controller that includes a first and a second control stage. The first control stage includes a sensor for measuring force on the stone retrieval basket when the lock mechanism is in an unlocked position, and the second control stage includes a sensor for measuring force when the lock mechanism is in a locked position.

Abstract: A forceps including a gripping assembly. The gripping assembly includes an upper jaw and a lower jaw. The upper jaw includes a proximal end and a distal end. The upper jaw includes an upper tooth having an upper proximally facing canted tooth surface and an upper distally facing canted tooth surface. The lower jaw includes a proximal end, and a distal end. The lower jaw includes a socket having a lower distally facing canted socket surface and a lower proximally facing socket surface. The upper jaw, the lower jaw, or both are moveable so that the gripping assembly moves between an open position and a gripping position. In the gripping position, a gap is defined between the upper distally facing canted tooth surface and the lower proximally facing socket surface.

Abstract: An instrument including a first arm, a second arm, and a blade. The first arm includes a lumen in communication with a source of irrigation fluid and one or more outlets in communication with the lumen for delivering the irrigation fluid to a surgical site. The instrument is switchable between a first configuration and a second configuration. In the first configuration, the instrument is configured to deliver a first therapy current through a distal end of the first arm, a distal end of the second arm, or both. In the second configuration, a distal end of the blade extends beyond the distal end of the first arm and beyond the distal end of the second arm.

Abstract: An electrosurgical medical device that includes a jaw assembly. The jaw assembly includes a first jaw body and a cutting member; and a second jaw body. During a first use state, the medical device is configured to pass a therapy current supplied by a power source between the first jaw body and the second jaw body to electrosurgically effect an anatomical feature. During a second use state, an anatomical feature is electrosurgically effected by contacting the anatomical feature with a medial edge of the cutting member while a second therapy current from the power source is passed between the cutting member and the first jaw body and/or the second jaw body.
