Abstract:
A vertebral rod includes a first elongated section having a first thinned portion. A second elongated section has a second thinned portion. An intermediate section has a flat, thin configuration, and is connected with and disposed between the first section and the second section. The flat, thin configuration of the intermediate section is disposed in an orientation transverse to at least one of the first thinned portion and the second thinned portion.
Abstract:
Embodiments for a spinal implant having elements that are accessible by a surgical approach and releasably engagable by a surgical tool for improved revision of the spinal implant about a patient's spine.

Abstract:
Methods and devices for providing a stabilized implant at a site of implantation include providing locking members on faces (108,110) of the implant and applying bone cement to the implant faces (103,105). The locking members secure the bone cement so that the bone cement will not be substantially displaced when the implant is inserted at an implantation site.
Abstract:
A tissue extender includes a ring defining a proximal end opening to engage a head of a subcutaneous screw, a first extender portion coupled to the ring at a proximal end of the first extender portion, and a second extender portion coupled to the ring at a proximal end of the second extender portion. The first extender portion includes a first coupling portion disposed at a distal end of the first extender portion, and the second extender portion includes a second coupling portion at a distal end of the second extender portion. The first and second extender portions define two side openings disposed on opposite sides of the tissue extender. The distal ends of the first and second extender portions together define a distal end opening. The first coupling portion engages the second coupling portion when the tissue extender is in an extended state. The distal end opening is larger in the extended state than in an unextended state.
Abstract:
A surgical implant containing two opposing shells (20, 40), a central body (60) disposed between the shells, and a flexible sheath (70) extending between edges of the opposing shells. The sheath is formed from a composite structure comprising a flexible material (1000, 1003) and a resistant material (1002) that provides for resisting at least one predetermined type of relative directional motion.
Abstract:
ABSTRACT A prossthetic device according to which a time-dependent degree of resistance is provided to at least one predetermined type of relative directional motion between first and second components of the device.
Abstract:
This invention relates to a metal composite orthopedic device such as an articulating spinal spacer (60, 90). The device can comprise a metallic substrate (62, 96) cladded or joined to one or more metallic layer(s) (68, 98). The substrate and metallic layer(s) can be selected of different metals and metal alloys to provide desired wear performance, imaging characteristics and optionally to serve as a reservoir for therapeutic agents.
