Patent number: 7322978Abstract: 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.Type: GrantFiled: June 22, 2004Date of Patent: January 29, 2008Assignee: HS West Investments, LLCInventor: Hugh S.

Patent number: 7244256Abstract: 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.Type: GrantFiled: June 10, 2004Date of Patent: July 17, 2007Assignee: Linvatec CorporationInventors: Michael DeCesare, Hugh S.

Patent number: 7235078Abstract: A protective device for use with an interference screw used to attach a soft tissue graft within a bone tunnel reduces the tendency of the interference screw to undesirably snag a soft tissue graft and/or sutures when screwed into a bone tunnel. The protective device has an angled face that corresponds to an angled face of the interference screw and threads that correspond to the threads of the interference screw. When used together, the protective device effectively completes the part of the interference screw that is removed to form the angled face. This, in turn, reduces or eliminates any sharp edges that would otherwise catch or snag the tissue graft and/or sutures as the interference screw is screwed into a bone tunnel during a joint repair procedure. The protective device may be included within a kit together with a correspondingly sized and shaped interference screw, and optionally with a driver.Type: GrantFiled: November 26, 2002Date of Patent: June 26, 2007Assignee: HS West Investments LLCInventor: Hugh S.

Patent number: 7150746Abstract: 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.Type: GrantFiled: June 10, 2004Date of Patent: December 19, 2006Assignee: Linvatec CorporationInventors: Michael DeCesare, Hugh S.

Patent number: 7118578Abstract: 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.Type: GrantFiled: August 29, 2003Date of Patent: October 10, 2006Assignee: HS West Investments, LLCInventors: Hugh S. West, Jr., John R. West

Patent number: 6953463Abstract: An interference screw for affixing soft tissue grafts during anterior cruciate ligament (ACL) reconstruction comprises a threaded body axially extending between a face and a tip along a central axis, with the face advantageously being obliquely aligned with the central axis. The threaded body includes a proximal threaded section and a distal threaded section, each of which may be straight or tapered. The proximal threaded section is approximately 1 mm larger in diameter than the distal threaded section. The increased diameter of the proximal threaded section enables the interference screw to compressively secure the soft tissue graft against the cortical bone, while the distal threaded section compresses the soft tissue graft against the cancellous bone with an appropriately reduced force that is appropriate for facilitating bonding of the soft tissue graft to the cancellous bone and that is sufficient for minimizing any “bungee effect.Type: GrantFiled: October 12, 2001Date of Patent: October 11, 2005Assignee: HS West Investments, LLcInventor: Hugh S. West, Jr.

Patent number: 6679889Abstract: 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 onto individual strands of a multiple-stranded soft tissue graft, such each of a pair of ham strings. The inventive methods advantageously ensure that each strand of a multiple-strand soft tissue graft is adequately tensioned so as to both “condition” the graft to prevent subsequent stretching, relaxation or elongation following surgery, which can destabilize the joint, and pre-tension each strand of the graft to a desired amount so that each significantly contributes to the strength and stability of the joint, thus resulting in a stronger and more durable joint.Type: GrantFiled: November 13, 2000Date of Patent: January 20, 2004Assignee: HS West Investments, LLCInventors: Hugh S.

Patent number: 6618626Abstract: 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.Type: GrantFiled: August 29, 2001Date of Patent: September 9, 2003Assignee: HS West Investments, LLCInventors: Hugh S.
