A pull on a release wire (32) at one end of the coil (30) detaches the coil from at least one of the helical wires whereby to detach the medical device (10) from the deployment member (16). In a modification a release coil (130) is arranged between concentric helical wires (112, 118).

Abstract: A surgical clip is provided for ligating or transecting tissue, such as vessels, other tubular ducts, and the like and a surgical clip applier device for delivering and applying the surgical clip to the tissue. The surgical clip can include a spine and opposed arms extending from the spine where the arms can define a clamping length. In a resting state, the clip can be biased to a closed position such that the ends of each opposed arm are disposed in proximity to each other. With such biasing, when applied to a tissue, such as with a surgical clip applier, the clip can exert a positive clamping pressure to the tissue along the clamping length to seal the tissue and limit passage of fluids, such as blood, from the tissue.

Abstract: An ultrasonic treatment instrument includes a vibration transmitting member transmitting ultrasonic vibration toward a first gripper and formed as one piece, and a second gripper movable between a spaced position where the second gripper is spaced apart from the first gripper and a closed position where the second gripper is put in close to the first gripper. The ultrasonic treatment instrument includes an interlocking actuator increasing, by moving the first gripper in interlock with a movement of the second gripper to the spaced position, a spacing distance between the first gripper and the second gripper in accordance with a movement of the first gripper.

Abstract: A suture anchor system and method including a suture anchor and a suture anchor drive. The suture anchor is positionable on a rod of the suture anchor drive. The rod defines an awl for forming a hole in a bone. The suture anchor drive further has an impactor for moving the suture anchor along the rod between a retracted position and an advanced position so as to implant the suture anchor in the bone with the awl positioned in the bone.

Abstract: The devices and methods described herein relate to improved structures for removing obstructions from body lumens. Such devices have applicability in through-out the body, including clearing of blockages within the vasculature, by addressing the frictional resistance on the obstruction prior to attempting to translate and/or mobilize the obstruction within the body lumen.

Abstract: A beak trimming device is provided. The device includes a trough operative to receive an avian attractant. The trough has an inner surface. The inner surface includes one or more abrasive surfaces configured to contact and trim a beak of a bird accessing the attractant at the trough. In some embodiments, the attractant is feed.

Abstract: The present disclosure relates to catheters for delivering medical devices to a human patient's vasculature. A catheter comprises a sock which covers the medical device at the end of the catheter, and an introducer sheath which is reduced in diameter. This reduced diameter introducer sheath minimizes the crossing of the catheter.

The surgical tool has a portion that is suitable to provide a reference portion of the surgical tool, and the optical sensor has an end fixed relative to the reference portion of the surgical tool such that the reference portion of the surgical tool can be detected along with tissue that is proximate or in contact with the distal end of the surgical tool while in use.

Abstract: A detachment mechanism for an introducer assembly is designed to hold a coupling element of an implantable medical device until its desired release within a patient's vessel. The detachment mechanism includes a body portion having first and second gripper arm elements which grip onto the coupling element of the medical device. The gripper arms are naturally biased into a closed position by means of resiliency of the body element. For this purpose, an actuating device or opening element is provided which includes an enlarged head which can be pulled against tapering internal surface of the body portion of the detachment mechanism in order to force the gripper arms open, thereby to release the medical device from the introducer assembly. The detachment mechanism, being naturally in the closed configuration, reliably holds a medical device to the introducer assembly until it is desired to release the latter into the patient's vessel.
