Abstract: Suture anchors for securing therapy delivery elements, such as stimulation leads or catheters, within a living body. The suture anchor includes an inner sleeve constructed with an inner layer of a softer, more pliable material that easily conforms to the therapy delivery element to reduce slippage and an outer layer constructed from a harder, stiffer durometer material that protects the therapy delivery elements from damage due to over-tightening the tie down sutures. A suture material located in the suture groove is tensioned to apply a radial compressive force. The reinforcing structure spreads the radial compressive force along a greater surface area of the therapy delivery element.

Abstract: A mechanical connector designed to connect an orthopedic tool to a handle or motor. The connector includes a locking ball and spring-load sleeve mechanism that compresses a ball into an annular groove of the tool drive shaft, locking the shaft in the connector. The tool drive shaft is released from the connector by applying a force to the housing in a proximal direction. A portion of the housing removes the locking ball from the groove of the tool drive shaft, unlocking the shaft from the connector as the housing travels in a proximal direction.

Abstract: Battery packs having electrically insulating material between conductive surfaces of electrical components are described herein. In some embodiments, a battery pack includes a battery cell with a first conductive surface, an electrically conductive member with a second conductive surface, and electrically insulating material positioned between the first and second conductive surfaces. The electrically insulating material has at least one passage that enables the first and second conductive surfaces to be electrically connected. For example, the passage in the electrically insulating material may be formed by, during, or as a result of a process in which the first and second conductive surfaces are attached, such as by a welding process that both ablates a portion of the electrically insulating material to form the through passage and that physically joins the first and second conductive surfaces, thereby creating an electrical connection therebetween.
