Abstract: A focused ultrasound ablation device and method includes an ultrasound emitting member having a plurality of individual ultrasound emitting elements arranged in an array. The ultrasound emitting elements are actuatable to emit ultrasound energy and focus the emitted ultrasound energy a predetermined distance from the ultrasound emitting member such that the ultrasound energy is focused within anatomical tissue adjacent which the ultrasound emitting member is positioned. The anatomical tissue is heated by the ultrasound energy focused therein to form an internal lesion within the tissue. The ultrasound emitting elements are selectively, independently actuatable, allowing selected ones of the ultrasound emitting elements to be actuated to emit ultrasound energy to obtain a lesion of desired or selected size and/or surface configuration in the tissue of a particular patient.

Abstract: A surgical interference screw includes an axial bore extending entirely through the screw and hexagonally or otherwise configured at least at its ends to be drivable from either end. A driver includes a shaft with a forward bone penetrating tip. The screw is slid onto the shaft to expose the tip forwardly of the screw prior to inserting the screw into bone tissue. The forward portion of the shaft has a hexagonal or other periphery to engage the bore and turn the screw. The top of the shaft protruding from the end of the screw may be variously shaped as a trocar, pick, twist-drill bit, or gimlet thread. Plural drivers may be provided with different tips for various tasks. The relatively thick shaft and long engagement area between the screw and driver prevent screw mis-alignment and loss. The hexagonal or similar socket at least at both ends of the screw permits engagement by the driver and revision from either end. Irrespective of which end is driven, the screw can be revised in either direction.

Abstract: A driving system and method for endoscopically inserting threaded suture anchors. The driving system incorporates a tubular guide adapted to receive a cylindrical drive shaft having a drive portion at its distal tip for engaging a threaded anchor and a stop member at its proximal end for enabling rotational motion of the drive system relative to the drill guide while limiting longitudinal motion beyond a predetermined point. The stop member is, in the preferred embodiment, an annular shoulder which prevents the drive shaft from advancing the anchor into the bone more than a desired amount sufficient to countersink the anchor below the bone surface. The invention facilitates use of a drive shaft having a minimized shaft diameter. The invention also comprises a method of using the driving system, the method comprising the steps of both turning and longitudinally limiting the motion of the driver from the proximal side of the driver.
