摘要： A system for single tunnel, double bundle anterior cruciate ligament reconstruction includes implant constructs and instruments. The implant constructs provide a combination of cortical fixation and bone tunnel aperture fixation. The implant constructs separate a graft into distinct bundles. The instruments are used to prepare shaped bone tunnels to receive the implant constructs and graft bundles. Methods for reconstructing the antero-medial and postero-lateral bundles of the anterior cruciate ligament may rely on single femoral and tibial tunnels and a single strand of graft.

摘要： A system for percutaneous fixation and stabilization of a fracture with a spanning, expandable structural frame placed in the intramedullary canal of the bone, comprising a column of surgical fluid such as bone cement, within which the structural frame acts as a reinforcing cage, and a sheath positioned at the fracture site and at least partially surrounding the frame and fluid. The fluid may be supported by a restrictor and may be agitated with a vibrating probe to remove entrapped air. The structural frame may be self-expanding or opened by an internal force, and it may be retrievable. The frame, fluid, or sheath may contain antibiotics, pharmaceuticals, or other therapeutic compounds to be delivered to the fracture site.

摘要： An electrosurgical instrument for ablating cartilage while limiting collateral damage includes a non-conducting head with a small electrically conductive surface. The head of the instrument is coupled to a shaft by a flexible portion. The flexible portion biases the electrically conductive surface towards a tissue surface. The head is pivotably coupled to the shaft such that the electrically conductive surface is oriented substantially parallel to the tissue surface as the head slides across the tissue surface. A method of performing electrosurgery includes positioning the electrically conductive surface adjacent to the tissue surface, and sliding the shaft across the tissue surface with the head pivoting such that the electrically conductive surface is oriented substantially parallel to the tissue surface.

摘要： A method and apparatus include determining a value of a parameter associated with operation of an electrosurgical probe having a particular probe design, and determining whether the value of the parameter is within a range of values that has been predetermined for the particular probe design to indicate that the probe is treating tissue in a desired manner. Power is delivered to the probe according to an algorithm based upon a determination that the value of the parameter is outside the range of values The algorithm delivers power in a pulsed profile including portions of low power and portions of high power. In one embodiment, the tissue treatment is ablation, the parameter is impedance, and the method limits tissue necrosis to less than 200 microns. In another embodiment, the tissue treatment is shrinkage, the parameter is temperature, and the method limits power delivery when the probe is not shrinking tissue.

摘要： An electrosurgical instrument includes a shaft, a flexible portion, and a head coupled to the shaft through the flexible portion and pivotably coupled to the flexible portion. The head includes a non-conductive surface and an electrically conductive surface. The flexible portion is configured to bias the non-conductive surface and the electrically conductive surface towards a tissue surface, such as cartilage. The non-conductive surface may include a material having a thermal conductivity less than or equal to about 30 W/m*K and/or a volume resistivity greater than or equal to about 1×1014 ohm*cm. The non-conductive surface may include a ceramic such as Macor® ceramic, ZTA ceramic, and/or 99.5% alumina ceramic.

摘要： A surgical rasping system functional in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system comprises a rasping head which may be low profile and offer a flat cutting/rasping surface, and is configured to be driven by an attached hub that translates a rotational movement into a reciprocating motion. Suction for removal of bone fragments or other tissues is provided through an opening spaced apart from or adjacent to the rasping surface. A radiofrequency ablation (RF) electrode may be carried on the rasping system to provide ablation or coagulation of soft tissues.
