Abstract: The invention relates to an injector with a valve chamber which is contained in an injector housing and can be loaded by way of an inlet from the high-pressure accumulation chamber. This valve chamber loads a nozzle inlet to an injection nozzle by means of a control element that can be moved in the injector housing upon the pressure relief of a control chamber. On the control element, which is embodied of one part or multiple parts, a control surface is disposed in the pressure relief region of the nozzle inlet.

Abstract: The present application discloses instruments for use in an endoscopic discetomy procedure which are configured to be disassembled for cleaning and reassembled for subsequent utilization. The preferred embodiments include endoscopic rongeur-style instruments which may be used to remove calcification, to trim away part of a bone and to remove tissue and tissue samples for biopsy purposes.The endoscopic surgical instruments of the present application are provided with a handle mechanism, an elongated endoscopic portion extending from the handle mechanism and a tool mechanism supported at a distal end of the endoscopic portion. The handle mechanism includes a body portion having an upper and a lower body portion, a stationary grip extending from the body portion and a pivotable grip pivotally mounted to body portion. In one embodiment, the pivotable grip is detachably mounted to body portion by a locking member which includes a fastener having a rod and an abutment portion.

Abstract: A bone stabilization implant comprises a single piece of material machined to include a bone plate portion having a length with a center line, a bone contact surface and an outer surface. The bone plate portion has a plurality of openings extending through the outer surface and the bone contact surface and are located at positions along the length of material. The openings are sized to receive a conventional bone screw. The outer surface is machined to include a plurality of integral bosses positioned at locations along the length. Each of the bosses has crimping surfaces and a pair of holes therethrough that are sized to receive cable. Each of the bosses is deformable to clamp cable received in the pair of holes when the crimping surfaces are crimped. The integration of the bosses with the underlying bone plate portion better facilitates handling of the implant during implantation procedures and substantially reduces the breakage and wear problems associated with prior art bone stabilization implants.
