摘要： Bone anchors are provided having three suture attachment sites disposed within a bore. The bone anchors are suitable for use in rotator cuff repair procedures. The bone anchors comprise an anchor body having a bore that opens at a proximal end of the anchor body. At least three attachment sites are positioned within the bore. Each attachment site is capable of slidably receiving a respective suture thereon. The three attachment sites are spaced apart and configured such that the portions of the respective sutures that are in contact with the three attachment sites are maintained separated during use. In one embodiment, the three suture attachment sites are provided by two transverse pins placed within the bore. In another embodiment, the bore opens at a distal end and a longitudinal pin is inserted into the opening at the distal end. The at least three attachment sites are provided by the longitudinal pin disposed within the bore. The bone anchors can be fully threaded and can have fine thread and coarse threads for engaging cortical and cancellous bone tissue, respectively.

摘要： Suture separation and organization devices for use in a tissue graft tensioning system. The inventive devices help to separate and organize a plurality of suture strands that extend away from a bone tunnel of a patient's leg during joint repair surgery (e.g., while repairing or replacing the anterior cruciate ligament (“ACL”)). The suture separation and organization device may comprise one or more elongate bodies, or a one-piece body, comprising a plurality of suture retention recesses or protrusions disposed on a perimeter of a body. The suture separation and organization device also includes recesses or passages adapted to receive corresponding posts of a graft tensioning device. In this way, the suture separation and organization device can be removably attached to the graft tensioning device.

摘要： Improved bone anchors are disclosed for anchoring one or more sutures attached to soft tissue to a bone. The bone anchor has an anchor body that extends between a distal and a proximal end. A bore is formed axially in the anchor body and opens at the proximal end. One or more pins are fixed within the bore of the anchor body. One or more sutures can be looped on the pins for anchoring soft tissue to bone. The anchor body has a socket within the bore for receiving a driver tool. The distal end of the anchor body forms a non-threaded extension, which stabilizes the bone anchor, and helps prevent lateral movement during use. In one embodiment, the anchor body has coarse threads for engaging soft bone tissue and fine threads for engaging hard bone tissue.

摘要： Bone anchors useful in rotator cuff repair optimize the thread pattern for engaging different types of bone tissues, including harder cortical bone and softer cancellous bone. Bone anchors may include fine threads for engaging cortical bone and coarse threads for engaging cancellous bone. Threads can be made finer by increasing root diameter and surface angle of the threads. The pitches of the fine and coarse threads are kept the same, which allows fine threads to follow the impression created by coarse threads as the anchor is driven into a bone. Threads that engage cortical bone can be multi-fluted and include a first flute that follows the same thread pattern as coarse threads such that first flute follows the groove created by the coarse threads as the bone anchor is driven into a bone. Bone anchors can have a distal non-threaded stabilizing extension at the distal end.

摘要： An electrosurgical device having an electrode and an insulating piece such as a ceramic insulator is disclosed. The electrode includes an active surface for ablating and/or coagulating tissue in an electrosurgical procedure. The insulating piece surrounds the active surface and provides a barrier for the intense heat created during ablation. The insulating piece is also electrically nonconductive to prevent unwanted discharge of energy. Electrode has a retaining ledge configured to engage a lip formed on the insulating ring. The insulating ring is secured to the electrosurgical device by connecting the electrode to an electrode seat and capturing the insulating piece in between. The electrode can be connected to the electrode seat by projection welding. The insulating piece is connected to the electrode without the use of an adhesive.

摘要： Electrosurgical devices for ablating tissue and methods of making the same are disclosed. The electrosurgical devices include an electrode with a lumen for aspirating gasses and debris produced during surgery. The electrode also includes a plurality of upper active edges for ablating tissue in an electrosurgical procedure. The upper active electrodes are spaced apart to form a filter that filters out large tissue particles from being aspirated into the lumen. The upper active edges ablate the large particles to form particles that can pass into the lumen. A lower active edge is formed at the terminal end of the lumen for ablating tissue being aspirated into the lumen. The lower active edge prevent tissue particles from occluding the opening to the lumen.

摘要： An anchor device for mounting a bodily tissue to a bone, such as for repairing ligaments and tendons, particularly ham string tissue grafts for repairing a knee joint. The anchor device is configured and sized to pass through a bone tunnel and comprises a sheath member having a bone-engagement end and bodily tissue attachment end. The bone-engagement end includes structure for selective overlapping and engaging the bone adjacent an exit opening of the bone tunnel. The bodily tissue attachment end includes structure known in the art for attaching a bodily tissue, such as a ligament, tendon, or ligament graft, to the sheath member. The anchor device further includes a camming member slidably disposed relative to the sheath member, which selectively urges the sheath member to engage the bone surface. The sheath member and camming member include interlocking features for locking the anchor device in a deployed position within the bond tunnel. The anchor device also includes structures which give the surgeon a tactile, aural or other indication when the anchor device has been deployed and locked in the deployed position. The anchor device is preferably inserted, deployed and locked by means of a system of suture cords in order to reduce the number of incisions necessary to anchor the bodily tissue to the bone.

摘要： Apparatus and methods for conditioning and pre-tensioning soft tissue grafts during joint repair surgery, such as during repair of the anterior cruciate ligament (ACL). The inventive apparatus is advantageously adapted and configured so as to enable a surgeon to independently apply a desired tensile load to individual graft strands or graft bundles of a multi-strand tissue graft. The inventive methods enable each graft strand or bundle to be properly tensioned so as to both “condition” the graft to prevent subsequent stretching, relaxation or elongation following surgery, which can destabilize the joint, and to pre-tension each graft strand or bundle to a predetermined amount so that each contributes to the strength and stability of the joint, thus resulting in a stronger and more durable joint. The tensioning device is advantageously equipped with structure for attachment to a patient's limb during the conditioning and pre-tensioning procedure. It has multiple adjustable tension applicators that can be independently manipulated so as to apply a separate tensile load to one or more ends of a tissue graft strand attached to each adjustable tension applicator.

摘要： This invention provides apparatus and means for protecting the axillary nerve during thermal capsullorhaphy. An electrosurgical probe is attached to a standard electrosurgical generator that is capable of producing coag waveforms. RF energy is generated by the generator in coag waveform and applied to discrete locations of the capsular ligaments through the electrosurgical probe. Noise produced by the coag waveform stimulates the axillary nerve, even in saline environments, thereby identifying the high-risk regions of the capsular ligaments that should be avoided during the procedure.

摘要： A monopolar electrode for use with a standard electrosurgical pencil and generator suitable for performing tissue ablation at relatively low power levels. The electrode has a cylindrical rim at its distal tip, the exposed conductive area of the cylindrical rim being minimized to create high powered densities sufficient for tissue ablation. The distal end of the electrode is surrounded by a ceramic insulating sleeve and an annular insulating gap is interposed between the electrode and the ceramic sleeve. A tubular polymeric insulating sleeve is applied to the outer surface of the electrode and to the outer surface of the proximal end of the ceramic sleeve.
