Patent number: 9808241Abstract: A suturing apparatus comprises a pair of jaws. A bendable needle housed in one of the jaws is adapted to carry a suture. An optional suture receiver may be disposed adjacent to the opposite jaw. A transition block curves the needle and directs it in a direction generally unparallel to an axis of the carrying jaw. The needle may also be configured to retrieve a suture. A retaining mechanism holds a suture in place to be engaged by the needle. The jaw housing the needle may include a lateral opening through which the suture may be inserted. The needle may also include a lateral notch which may be aligned with lateral opening to receive the suture. An actuator coupled to the needle enables the user to move the needle proximally to align the notch with the lateral slot.Type: GrantFiled: April 3, 2013Date of Patent: November 7, 2017Assignee: MEDOS INTERNATIONAL SARLInventors: Christopher Weinert, Ron Farkash, Dan Nelsen, Breck Petrillo, Michael C.

Publication number: 20120053627Abstract: A suture anchor assembly includes a suture anchor having a body, the body having a path for threading a suture therethrough. It also includes a suture threader received within the body through the path. The suture threader is an elongated tube having an expanded first end outside of the body adapted to receive suture therein and a closure mechanism for closing the expanded end about the suture whereby to allow the suture to be held by the tube and pulled through the path the load the suture into the body.Type: ApplicationFiled: August 11, 2011Publication date: March 1, 2012Applicant: DePuy Mikek, Inc.Inventors: Erik Sebastian Sojka, Arthur G.

Publication number: 20060156875Abstract: A fluid jet cutting system that provides more consistent cutting jet performance is disclosed. The system includes a fluid pump for pressurizing fluid having a fluid inlet and a fluid outlet. The pump delivers pressurized fluid to a delivery tube that is in fluid communication with an end effector. The end effector includes an orifice for delivering pressurized fluid to tissue. The power delivered to the pump is controlled to produce a desired fluid cutting jet.Type: ApplicationFiled: January 19, 2005Publication date: July 20, 2006Applicant: DEPUY MITEK, INC.Inventors: Ian McRury, Mehmet Sengun, Christopher Weinert
