A suture anchor has a pin that is disposed transversely within the suture anchor, over which one or more strands of suture is looped. The anchor body is threaded and has a tapered distal portion. The proximal end portion of the suture anchor body has a hexagonally shaped opening to accept a hexagonal drive head. The peripheral surface defining hexagonally shaped opening is rounded and smooth to prevent abrading sutures placed in contact therewith.

An insert-molded suture anchor has a biodegradable polymer body molded around a loop of suture. A tapered end disposed on the proximal end of the body is received into a recess in the distal end of a hand driver. Anchoring ribs are formed along the remaining length of the anchor. The suture is held securely within the anchor body during the insert molding process. The anchor is produced by placing the braided suture within an injection mold, and injecting biodegradable polymer into the mold. Using a preferred plication driver, the suture anchor can be utilized for capsular plication procedures.

Systems, assemblies and methods for assembling a sheath member with respect to a spinal stabilization device are provided. The disclosed sheath assembly includes at least one connector ring mounted with respect to a sheath member.

A steam engine increases efficiency and prevents corrosion, abrasion, and the like in a part receiving steam pressure. A heater and a cooler are provided on one side of a U-shaped fluid container, and a piston for output is provided on its other side. The heater heats working fluid to vaporize the fluid. The expansion pressure of steam of the working fluid depresses a fluid level in a first vertical pipe. The liquid component of the working fluid flows from the first vertical pipe into a second vertical pipe, thereby applying pressure to the piston in an upward direction. Then, the liquid component of the working fluid functions as a liquid piston directly receiving the expansion pressure of the steam, so that it is possible to prevent the occurrence of corrosion, abrasion and the like in the part receiving steam pressure.
