Publication number: 20120203289Abstract: An implant, such as a cranial implant, for attachment to a defect in a bone structure having an edge is described. The implant comprises a direction of extension and a rim extending substantially perpendicular to the direction of extension of the implant. The rim is configured to be attached to the edge of the bone structure and comprises at least one mounting portion configured to accommodate a fastener such that at least a portion of the fastener is extendible in a direction extending away from the rim at an angle which is at most acute with respect to the direction of extension of the implant. The implant is configured such that upon placing the implant in the defect, the fastener is extendible into the edge of the bone defect in a controllable manner.Type: ApplicationFiled: September 21, 2010Publication date: August 9, 2012Applicant: ACADEMISCH ZIEKENHUIS MAASTRICHTInventors: Maikel Michael Adrianus Beerens, Paul Frans Jozef Laeven, Jules Maria Nikolaas Poukens

Patent number: 8128670Abstract: A biocompatible surgical fastener, comprising a sleeve and a screw or a pin, which expands when it is implanted in a patient. The sleeve is first implanted in a pre-drilled hole in the operating area of a patient, usually in a bone, cartilage or a bone and cartilage. When a screw or a pin is installed in the sleeve, the sleeve is caused to expand thereby stabilizing the fastener in the operating area. In many embodiments the screw or pin can be removed and reinserted without disturbing the tissue in the operating area. The surgical fastener can be used to repair tissue or to secure other implant devices in a patient.Type: GrantFiled: April 15, 2005Date of Patent: March 6, 2012Assignee: BioDynamics LLCInventors: James D. Ralph, Stephen L. Tatar, Thomas N. Troxell

Patent number: 8109966Abstract: An innovative bone anchor and methods for securing connective tissue, such as tendons, to bone are disclosed which permit a suture attachment which lies entirely beneath the cortical bone surface, and wherein the suturing material between the connective tissue and the bone anchor is oriented in a direction generally transverse to the longitudinal axis of the bone anchor, so that axial pull-out forces exerted on the bone anchor are minimized. The suture attachment to the bone anchor involves the looping of a substantial length of suturing material around a shaft of the anchor, thereby avoiding an eyelet connection which requires a knot and which concentrates stress on a very small portion of the suturing material. Thus, failure rates are greatly decreased over conventional techniques, and the inventive procedures are significantly easier to perform than conventional techniques.Type: GrantFiled: July 17, 2007Date of Patent: February 7, 2012Assignee: ArthroCare CorporationInventors: Mark A.

Patent number: 8002778Abstract: A method for securing a soft tissue replacement in a bone tunnel includes forming a first and second tunnel in the bone. The second tunnel intersects the first tunnel and defines a first and second access passage. A first flexible member is passed through the tunnel and includes a first end extending out of the first passage, an intermediate portion supporting the soft tissue replacement and a second end extending out of the second passage. The first end of the first flexible member is fastened to an insertion member. A crosspin is positioned between the first passage and the insertion member. The second end of the first flexible member is advanced until a distal portion of the crosspin advances into the first access passage. The insertion member is impacted thereby pushing the crosspin into an engaged position with the bone.Type: GrantFiled: June 28, 2004Date of Patent: August 23, 2011Assignee: Biomet Sports Medicine, LLCInventor: Jason D Meridew

Patent number: 7955388Abstract: System, including methods, apparatus and components thereof, and kits, for connecting to bone using an anchor element configured to be anchored in bone and having a selectively bendable hinge region. In some embodiments, the system may connect the anchor element to connective tissue, a bridge member, and/or to another anchor element by bending the hinge region while the anchor element is disposed in bone, thereby connecting bone to the connective tissue or bridge member, and/or connecting bone members.Type: GrantFiled: October 30, 2007Date of Patent: June 7, 2011Assignee: Acumed LLCInventors: David G. Jensen, Steven P. Horst

Patent number: 7931651Abstract: An external fixation assembly includes a plurality of hollow pins that are inserted into a patient's bone. Each pin has an interior bore and a plurality of apertures extending through the pin wall from the bore. The pin may be coupled to a source of vacuum pressure operable to create reduced pressure in the tissue surrounding the pin. A cover is placed around the pin and sealed to provide a fluid-tight enclosure that maintains reduced pressure around the pin. A method for applying external fixation using the fixator pins described above includes the steps of inserting each pin through a skin opening, positioning the pin apertures near selected tissue, covering the skin opening with a sealed enclosure, connecting the pins to a source of vacuum pressure, and activating the source of vacuum pressure to create reduced pressure in the patient's tissue at or near the bone.Type: GrantFiled: March 30, 2007Date of Patent: April 26, 2011Assignee: Wake Lake University Health SciencesInventors: Lawrence X. Webb, Louis C. Argenta, Michael J. Morykwas

Patent number: 7828848Abstract: An expandable osteosynthesis implant has branches each connected at one end to a seat which is pierced by an orifice, suitable for being slid from a posterior direction between the facing faces of two consecutive vertebrae in order to hold them a given distance apart and restore stability of the spinal column. The branches and the seat define a hollow cage which, in a “rest” position, has an outside general shape that is a cylinder of circular section, and a portion at least of the inside volume of the cage towards the distal ends of the branches is in the form of a circular truncated cone whose large base is towards the seat, which implant has at least three branches and, inside the inside volume at least one spacer suitable for passing through the orifice and the large base of the truncated cone.Type: GrantFiled: April 16, 2002Date of Patent: November 9, 2010Assignee: Wenzel Spine, Inc.Inventors: Jean-Luc Chauvin, David Attali, David Attia

Patent number: 7819906Abstract: A surgical rivet device for the repair of torn menisci and other intra-articular bodily tissues is disclosed in which the device comprises a shaft, projecting fins and a penetration head at one end and a wide rear portion. The device is inserted by a driving mechanism through both sides of the torn meniscus, compressing the tear in the meniscus between the fins near the head and the wide rear portion, holding the tear together. After insertion, the driving mechanism is separated from the rivet, leaving the rivet device in the patient. The rivet device is entirely biodegradable and absorabable by the body.Type: GrantFiled: December 12, 1994Date of Patent: October 26, 2010Inventor: Gary Karlin Michelson
