A remotely-activated injection device for use in vertebroplasty is provided to inject a fluorescent probe material into a patient. The injection device includes a pump defining an injection chamber having an exit opening; an actuator; and a cable having a first end coupled to the actuator, and a second end remotely engaging the pump. The actuator remotely controls the pump by responsive movement of the cable to thereby cause injection of a fluorescent probe material from the injection chamber of the pump through the exit opening to the patient.

Remotely-activated vertebroplasty injection device

A remotely-activated injection device for use in vertebroplasty is provided to inject a flourescent probe material into a patient. The injection device includes a pump defining an injection chamber having an exit opening; an actuator; and a cable having a first end coupled to the actuator, and a second end remotely engaging the pump. The actuator remotely controls the pump by responsive movement of the cable to thereby cause injection of a flourescent probe material from the injection chamber of the pump through the exit opening to the patient.

The present invention relates to trans-capsularly administering into a diseased joint a high specificity antagonist selected from the group consisting of:

An orthopaedic method and anchor assemblies for anchoring a linkage such as a rod or cable used for fixation or reduction. One assembly includes an anchor plate and a slotted anchor bolt that captures the plate in a one-piece assembly for convenient installation. The base of the anchor bolt lies below the plate, and a cap or nut tightens down to secure a linking member, e.g., a rod or cable, in the slot, simultaneously clamping the bolt to fix both its position and its orientation on the plate. One occipital plate has lateral arms that hold the anchor bolts, and a Y-shaped embodiment is mounted in an inverted orientation to position the anchor bolts well down in soft tissue for more effective wound closure. A cable connector is used together with an anchor plate, vertebra anchor screws and fixation rods to secure ends of a cable at the level of one or more vertebrae, providing a versatile and highly stable system for alignment, fixation and fusing of the cervical and thoracic spine. The cable connectors have an open-sided channel that fits onto and securely clamps to an already-positioned fixation rod, with an eyelet or other structure providing a rigid and fixed securing point for a cable that is threaded about the vertebrae under tension. Methods of fixation are described.

Orthopaedic rod/plate locking mechanisms and surgical methods

An orthopaedic junction or anchor assembly for anchoring a linkage such as a rod or cable used for fixation or reduction. The assembly includes a slotted bolt that fits through an apertured plate, and a support platform that fits over the bolt, capturing the plate in a one-piece assembly for convenient installation. The base of the bolt is recessed in the plate and a cap or nut tightens down to secure the linking member, e.g., a rod or cable, in the bolt slot, simultaneously clamping the bolt to fix both its position and its orientation on the plate. The support platform has the form of a generally annular washer with an upper surface including a transverse groove on which the rod seats, and a lower surface abutting the plate. A sleeve potion may extend within and buttress the surrounding wall of the plate. The plate may take various forms, such as a hook or offset arm, an occipital T-plate, or a vertebra plate. In one embodiment the support platform is swaged to the bolt, allowing the bolt to rotate freely, and slide along the slot of the bone plate as a captive assembly, keeping all the components together without constraining the alignment during installation. Other embodiments employ mating ridge and groove, or other detents circumferentially on the bolt shaft and the inner face of the support, to snap and retain the pieces together. When the rod or other linkage has been positioned, a lock nut or cap then fastens onto the bolt to seat the rod against the support platform and lock both the position of the bolt and the angular orientation of its slot. Tightening the nut or cap pushes the rod downward to seat on the support plate and pulls the bolt upward to press the base of the bolt against the bottom of the plate. The bottom surfaces of the support washer as well as the plate-facing surface of the base may be roughened or textured to engage the plate, or otherwise increase resistance to rotational and lateral movement once the rod has been positioned and the nut is torqued down.

A method of controllably heating the annulus of an intervertebral disc is disclosed. The method comprises the steps of forming an access channel through the annulus, inserting a light source into the intervertebral disc, activating the light source to emit diffuse light, optically measuring the temperature of tissue near the light source, and modifying the intensity of the light emitted from the source according to the measured temperature.
