Publication number: 20140088589Abstract: 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.Type: ApplicationFiled: November 26, 2013Publication date: March 27, 2014Inventors: Douglas M.

Publication number: 20140066931Abstract: External fixation systems, and methods for immobilizing joints or fractured bones. An external fixation system may include one or more clamp assemblies connected to one or more rod assemblies at polyaxial joints. Each rod assembly may be length adjustable, and may include a one-way locking mechanism to provisionally lock the length of the rod assembly, and additional locking mechanisms to permanently lock the length of the rod assembly. The system may be deployed pre-assembled as a unit to immobilize a joint or fracture. Another external fixation system further includes a spanning member extending transverse to the rod assemblies. Two or more external fixation systems may be deployed in a stacked configuration on one set of bone pins to immobilize two joints and/or fractures. The systems may be provided in kits including guiding instrumentation, bone pins and pin clamping assemblies for connecting the bone pins to the external fixation systems.Type: ApplicationFiled: August 7, 2013Publication date: March 6, 2014Applicant: IMDS CorporationInventors: Thomas H.

Publication number: 20140018787Abstract: 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.Type: ApplicationFiled: July 2, 2013Publication date: January 16, 2014Inventors: Kobi Iki, William M.

Publication number: 20130331941Abstract: 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.Type: ApplicationFiled: August 16, 2013Publication date: December 12, 2013Applicants: IMDS CorporationInventors: Thomas H.

Publication number: 20130304070Abstract: A surgical rasping and/or shaving system functions in multiple orthopedic applications, including but not limited to shoulder, knee, hip, wrist, ankle, spinal, or other joint procedures. The system may comprise a tissue removal member with a rasping and/or shaving head which may be low profile and offer a flat cutting/rasping/shaving surface, or with a cutting head with at least one cutting edge. The tissue removal member 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 system to provide ablation or coagulation of soft tissues.Type: ApplicationFiled: April 18, 2013Publication date: November 14, 2013Inventors: Keith J.

Patent number: 8328815Abstract: Accessing a spine from a curved postero-lateral approach may include a curved cannula positioned along a curved path from an opening in the skin to a location proximate to the spine. Positioning of the distal end of a radiolucent curved access cannula may be assisted by use of one or more radio-opaque markers. Markers may be positioned to form a cross hair image in fluoroscopy to assist in cannula placement. Radio-opaque inserts placed in and extended beyond the curved access cannula may have radiolucent windows to allow viewing of the cannula's radio-opaque markers. An appropriately placed curved access cannula may be clamped to prevent subsequent movement. Appropriate tools may be introduced through the curved access cannula and the distal radio-opaque tool heads may be viewed relative to the radio-opaque markers. The curved access cannula may be attached to the spine through one or more screws.Type: GrantFiled: August 7, 2009Date of Patent: December 11, 2012Assignee: Innovative Spine, LLC.Inventors: Morteza M.

Patent number: 8177796Abstract: An endoscopic surgical instrument for passing a suture through tissue includes a first jaw member, a needle, and a capture feature actuable to grip and retain the suture after the suture has been passed through a tissue body. An actuation mechanism can both move the needle between retracted and extended positions, and move the capture feature between open and closed configurations, via a single actuation. The capture feature may be a trap door which is axially translatable relative to the first jaw member to overlap a portion of the first jaw member and trap a portion of the suture between the trap door and the overlapped portion. The first jaw member may be movable relative to a second jaw member to grasp a tissue body. The instrument can grasp a tissue body, pass the suture through the tissue, capture and retain the suture without being repositioned relative to the tissue.Type: GrantFiled: March 22, 2010Date of Patent: May 15, 2012Assignee: Linvatec CorporationInventors: Ephraim Akyuz, Andrew R.
