An electrosurgical device including an elongated body extending from a proximal portion to a distal portion and defining an internal passageway configured to convey tissue from the distal portion to the proximal portion, and a coring electrode positioned at the distal portion of the elongated body, where the coring electrode is at an opening to the internal passageway, and where the coring electrode is configured to deliver electromagnetic energy to adjacent tissue to cut a volume of the tissue as the tissue is conveyed into the internal passageway.

Energized corers with energized internals

A surgical instrument including a tool, a handpiece, and a locking member. The handpiece includes both a coupling member configured to cooperate with the tool, and a driver for rotating the tool. The locking member is movable from an unlocked position to a locked position in response to centrifugal force generated during rotation of the locking member. The locking member is configured to secure the tool to the handpiece when in the locked position.

Dynamic locking device

An intervertebral disc prosthesis comprises a first endplate, a second endplate, and a bearing surface positioned between the first endplate and the second endplate. The bearing surface may be provided by a mobile bearing disc including a convex bearing surface configured to engage the first endplate and a concave bearing surface configured to engage the second endplate. The multiple bearing surfaces of the mobile bearing disc engage articulating surfaces on the endplates to form a plurality of articulating joints. Each articulating joint is configured to facilitate a particular type of movement for the segmental unit. Furthermore, each articulating joint is defined by a distinct center of rotation. The contact pair formed by the convex bearing surface of the bearing component and the concave bearing surface of the first endplate may provide a flexion/extension center of rotation for the prosthesis.

Disc prosthesis having remote flexion/extension center of rotation

The present invention relates to a dynamic stabilization system (DSS) having at least one rod having a ring formed therein ('the spring') and a pair of pedicle screws adapted for fixation to separate vertebrae.

Dynamic stabilization system

This invention relates to an intervertebral motion disc having two opposing endplates, a central articulating core, and a peripheral helical shock absorber.
