A device for clamping tissue includes a first jaw having a distal portion for communicating with tissue and a proximal portion having a first wing and a second wing. The device also includes a second jaw having a distal portion for communicating with tissue and a proximal portion having a first slot and a second slot, the first slot disposed between a middle structure and a first lateral structure, the second slot disposed between the middle structure and a second lateral structure. The first jaw is rotatably coupleable to the second jaw with the first wing extending into the first slot and the second wing extending into the second slot.

An implantable hearing aid transducer apparatus provides a simplified approach for interface with a middle ear component. The transducer includes a transducer housing, an actuator for middle ear coupling, and a driver having a magnet or coil interconnected to the actuator to induce movement in response to driver signals. In one feature, the actuator may be advanceable through an aperture of the housing independent from operation of the driver. In another feature, a portion of the transducer may be rotatable. In another feature, a retention apparatus may function to selectively secure a rotatable portion of the housing in a selected position. In an additional feature, a seal may be disposed around a driver component and connected to the actuator.

A harness routing structure for a sliding door includes harnesses that are routed between a vehicle body and a sliding door, and a guiding device that is provided along the harnesses and that guides the harnesses, wherein the guiding device has at the ends thereof installation portions that are respectively installed on the vehicle body and the sliding door, and a torsion-permitting portion for permitting twisting of the harnesses is provided along the harnesses in the installation portions.

An angled tissue cutting instrument includes an outer member having an elongate body with a bend and a forward end, and a distal tip rotatably mounted on the forward end. The distal tip and body are rotatable relative to one another about a central longitudinal axis of the tip to variably position a cutting window of the tip in a selected directional position about the axis. Relative rotation between the distal tip and the body about the axis is prevented to lock the cutting window in a selected directional position when the outer member is maintained in a longitudinally extended position by an inner member of the instrument disposed within the outer member. An indexing tool for the angled tissue cutting instrument has a socket for receiving the distal tip to effect rotational indexing. A method of variably positioning a cutting window of an angled tissue cutting instrument involves rotationally indexing a distal tip of an outer member of the instrument and maintaining the distal tip in a selected rotationally indexed position.

An anchor for a wear assembly on an excavating bucket is disclosed. The excavator bucket lip has a base having a nose, and the wear assembly includes a wear member having a cavity in which the nose can be received, and an aperture extending between an outside surface of the wear member and the cavity, an internally toothed ring being located within the aperture; and a lock for releasably holding the wear member to the base. The lock includes an operable member and an externally toothed resilient ring, the resilient ring having a central aperture for engagement with the operable member. The operable member and resilient ring are jointly rotatable relative to the cavity and the internally toothed ring between a plurality of rotationally spaced locking positions where the lock secures the wear member to the base with varying tightness, and a release position rotationally spaced from the locking positions. The teeth of the internally toothed ring and the teeth of the resilient ring engage each other in each of the locking positions to reduce the loosening of the lock during use.

A tool includes a housing including a receiving portion configured to receive at least a portion of an operating member so as to permit rotation of the operating member relative to the housing while constraining movement of the operating member in a radial direction of the operating member. The tool also includes a coupling device disposed on the housing and configured to couple the operating member to the housing so as to permit rotation of the operating member relative to the housing. The coupling device includes a retaining member configured to engage the operating member to constrain movement of the operating member relative to the housing in a longitudinal direction of the operating member. The retaining member is configured to rotate relative to the housing.

Bone anchor implantation devices and methods for their use are disclosed. The bone anchor implantation devices have an ergonometric and / or rotatable handle. The bone anchor implantation devices and methods find particular application for implanting a bone anchor for maintaining or improving urinary continence by suspending or stabilizing the bladder neck.

A modular pipe gripping assembly has a universal actuator assembly having a control fluid swivel. An external pipe gripping assembly can be attached to the actuator assembly for gripping the external surface of a section of pipe. Alternatively, the external pipe gripping assembly can be quickly and easily removed and replaced with an internal pipe gripping assembly for gripping the internal surface of a section of pipe. Control fluid pressure is trapped within the actuator assembly, but relieved from a fluid swivel, permitting high speed rotation of the modular pipe gripping assembly and preserving swivel seal life.

A feed assembly for an antenna having a non-circular reflector, in which the feed assembly includes a feed horn capable of correcting the distortions of circularly polarized signals caused by the non-circular reflector profile, and wherein the feed horn is coupled with a polarizer that is field-switchable between linear and circular polarization modes of operation. The feed assembly can include a second receive-only feed located in close proximity to the feed horn for communication with adjacent satellites.

A prosthetic intervertebral spacer includes a body and an interface extending away from the body for use during implantation of the spacer. The interface can be a rail including a neck portion connected to the body and a lip portion connected to the neck portion. The lip portion can be wider than the neck portion in a direction extending between the top and bottom surfaces of the implant. Methods of implanting the spacer and tools used during such procedure are also provided.
