Patent number: 8808313Abstract: A surgical instrument has a suture passer/advancer and a suture retriever manipulated from a common handle. The retriever is preferably a loop that closes around the suture advanced through it by the advancer. The loop is retracted to draw it around the suture. The passer/advancer has a fork-like distal end to readily advance and let go of the suture after it is in the loop of the retriever. The advancer and retriever can be manipulated longitudinally and rotationally with respect to a tubular body through which they extend so that the suture retriever can be passed through a needle pierced through tissue to be sutured, and the suture may be advanced and guided into the retriever loop to be gripped. Retracting the instrument will cause one end of the suture to be pulled retrograde through the tissue.Type: GrantFiled: July 12, 2007Date of Patent: August 19, 2014Assignee: Linvatec CorporationInventors: Marc Thorne, Darren W.

Patent number: 8449553Abstract: A guide that facilitates the creation of two bone tunnels for use during a “double bundle” cruciate ligament repair. In the case of an anterior cruciate ligament repair the guide facilitates the formation of two tibial tunnels extending between a single aperture on the anterior tibia and two distinct apertures on the tibial plateau. The guide has a single angled throughbore for guiding a drill bit on a predetermined angle relative to the anterior portion of the tibial tunnel. In an alternative embodiment the guide has two independent and non-intersecting bores which allow the simultaneous placement into the tibial tunnel of two separate guide pins to guide the formation of two tibial tunnels on the tibial plateau.Type: GrantFiled: March 20, 2012Date of Patent: May 28, 2013Assignee: Linvatec CorporationInventors: Andrew Kam, Hugh S.

Publication number: 20130090658Abstract: A guide pin gauge is described for use in measuring the thickness of an object at a particular location. The guide pin gauge includes a distal cutting head, a proximal shank having an outside diameter equivalent to an outside diameter of said distal cutting head, and a reduced diameter portion extending a length between the distal cutting head and the proximal shank. A proximal facing shoulder is provided at a transition between said distal cutting head and said reduced diameter portion. Markings are provided as a scale along said reduced diameter portion. The distal cutting head may be passed entirely through the hole, and displaced to a side such that a distal extent of the hole engages with the proximal facing shoulder. The markings may then be read to determine a distance to the distal extent of the hole.Type: ApplicationFiled: September 10, 2012Publication date: April 11, 2013Applicant: LINVATEC CORPORATIONInventor: Andrew KAM

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.
