One or more sutures can be advanced through the converging tunnels, and the suture(s) can be coupled to tissue. The suture(s) with the tissue coupled thereto can be tensioned, thereby helping to maximize an amount of the tissue in contact with the bone. In an exemplary embodiment, a guide device is provided that can be configured to allow a first tunnel to be formed in bone and to allow a plurality of additional tunnels to be formed in the bone at predetermined angular positions relative to the first tunnel such that each of the additional tunnels can extend transverse to the first tunnel and intersect the first tunnel.Type: ApplicationFiled: June 4, 2012Publication date: December 5, 2013Applicant: DePuy Mitek, Inc.Inventors: Benjamin Cleveland, Kristian DiMatteo, Erik S.

Patent number: 8597298Abstract: A reamer for reaming a proximal portion of a cavity for use in implanting a joint prosthesis is provided. The reamer is used for cooperation with a proximal portion of an orthopaedic implant component. The reamer includes a body defining a cavity formed therein for receiving at least a portion of the orthopaedic implant component. The reamer also includes a plurality of cutting edges extending outwardly from the body. The edges are adapted for cooperation with bone. The reamer also includes a stem extending from an end of the body.Type: GrantFiled: September 29, 2006Date of Patent: December 3, 2013Assignee: DePuy Synthes Products, LLCInventors: David W.

Publication number: 20130317340Abstract: An electromagnetic pedicle awl utilizes a tightly focused time-varying magnetic flux to create a localized electromotive force (EMF) near the tip. The localized EMF creates localized eddy currents in nearby nerves which excite ionic nerve channels, the excitation being detected by an electromyographic recording device. The awl only excites nerves directly in front of and directly to the side of the tip. The awl is comprised of a tapered awl or drill tip in combination with a solid core surrounded by a solenoid. A pulsed electric current source drives the solenoid to create a time-varying magnetic field in the vicinity of the tapered tip. The awl or drill tip may be stationary with respect to the solenoid or it may rotate. The awl in combination with an EMG detector connected to a patient is sensitive to the pedicle hole position with respect to adjacent nerves and reduces false placement failure.Type: ApplicationFiled: August 5, 2013Publication date: November 28, 2013Inventor: Erich Wolf, II

Publication number: 20130317508Abstract: A drill bit (1) has a tapered cutting end part (2) terminating in a drill tip (3), a shank (4) and a body (4a) extending between the cutting end part (2) and the shank (4). A plurality of flutes (5) are formed in the drill bit (1) and generally helically extend along the body (4a) into the cutting end part (2) to adjacent the drill tip (3). Each flute (5) has a flute leading side wall (6) and a flute trailing side wall (7). A land (9) is defined on the body (4a) between each of the flutes (5) and extends to the cutting end part (2). Each land (9) defines a secondary edge (11) with the flute trailing side wall (7) of the leading adjacent flute (5). Each secondary edge (11) helically extends to the cutting end part (2) at a secondary edge helix angle. A plurality of tip faces (14) are defined on the cutting end part (2) and each extend from one of the lands (9) to the drill tip (3). The tip faces (14) are separated by the flutes (5) up to adjacent the drill tip (3).Type: ApplicationFiled: February 10, 2012Publication date: November 28, 2013Applicant: CPL Holdings Pty.

Publication number: 20130317507Abstract: A minimally-invasive bone graft harvesting device, kit, and method are provided. The device includes a hollow cutting element and an extraction element. The hollow cutting element may define a longitudinal axis and includes a distal end, a proximal end adapted to be coupled to a powered or manual-operated rotary tool, and an inner lumen extending longitudinally between the distal and proximal ends. The hollow cutting element may also include one or more blades protruding from an outer surface of the cutting element. Each blade may be arranged adjacent to an opening extending between the outer surface and the inner lumen to allow cancellous bone material cut by each blade during use to pass through the opening into the inner lumen. The extraction element may be removably received within the inner lumen of the hollow cutting element to allow withdrawal of the bone material in the inner lumen.Type: ApplicationFiled: February 10, 2012Publication date: November 28, 2013Applicant: The Johns Hopkins UniversityInventors: Akhil Jay Khanna, Peter Hwa-Ming Truskey, Maxim Budyansky, Shoval Dekel, Haim Gottfried, Neil Shah, Khaled M.
