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.

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.

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 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.
