The device is also suitable for the fixation of a bone flap in the replacement thereof in a corresponding aperture made in the cranium or cranial bone mass. The device is made of biocompatible material and comprises a flexible strip and fastening means, the strip having a length allowing the formation of a fastening loop tightly fastening the bone fragments to be joined together. The fastening means are provided with at least one opening provided with interlocking means allowing the passage of a free end of the strip and preventing its extraction in the direction opposite to the insertion.Type: GrantFiled: December 4, 2012Date of Patent: April 15, 2014Assignee: Neos Surgery, S.L.Inventor: Lluis Chico Roca

Patent number: 8685037Abstract: A pair of clamps are attached to a damaged linear or non-linear bone one each side of a fracture site during a surgical reduction, one clamp on each side of the fracture site, after which the two clamps are slidably engaged to a pivotal alignment bar, with the clamps then being adjusted to properly align the linear or non-linear bone for a surgical attachment using a bone plate. The pivotal alignment bar provides at least one pivotal ball joint which may be aligned as a straight bar for a linear bone or adjusted to an angle for non-linear bones to achieve optimal alignment of the bone. Each clamp provides axially adjustable plate retainers which slides along a track on the end of each segment of the each clamp to position the retainers at a location where the bone plate is to be attached to the bone.Type: GrantFiled: March 30, 2010Date of Patent: April 1, 2014Inventor: Christopher Jordan

Patent number: 8663299Abstract: A cable fixation device comprises a clamp including a head portion and a body portion along with a lumen extending therethrough. The head portion is removably coupleable with an actuating mechanism. The lumen is sized and shaped to slidably accommodate a cable in combination with a clamping ring including a channel extending therethrough. The channel includes a first portion and a second portion. The first portion is sized and shaped to slidably accommodate the cable therethrough. The second portion is sized and shaped to engage the clamp. A portion of the clamp is movable between a first configuration and a second configuration, the cable slidable therethrough in the first configuration. The portion of the clamp moves radially inward in the second configuration to clamp the cable.Type: GrantFiled: June 10, 2010Date of Patent: March 4, 2014Assignee: Depuy Synthes Products, LLCInventors: Simon Stucki, Guido Hertig

Publication number: 20140046387Abstract: Disclosed is a clamping element for setting a bone fracture. The element comprises a flexible and substantially non-plastically deformable continuous loop inside which at least two fixing elements can be pushed through, and an extension element of alterable length that can be inserted into and is expandable inside the continuous loop in such a manner that in order to enable the extension element to apply forces to the fixing elements, said forces being directed towards each other, a predetermined tensile stress can be generated over the circumference of the continuous loop. Also disclosed is a setting device comprising the clamping element.Type: ApplicationFiled: January 25, 2012Publication date: February 13, 2014Applicant: Hipp Medical AGInventor: Markus Waizenegger

Publication number: 20140031882Abstract: A surgical reduction clamp has a first clamping arm and a second clamping arm movable relative to the first clamping arm. The first clamping arm comprises a base portion, a tip portion, a joint movably coupling the tip portion to the base portion, and a locking member adapted to lock the joint so as to fasten a position of the tip portion relative to the base portion. The joint is a revolute joint having a spherical portion which can be locked into position by a clamping force.Type: ApplicationFiled: July 24, 2013Publication date: January 30, 2014Applicant: Stryker Leibinger GmbH & Co. KGInventors: Manfred Schmuck, Denis Digeser, Uwe Koerner

Publication number: 20130345762Abstract: A device for reducing a bone fracture includes (a) a first arm extending from a handle at a proximal end to a distal end having a first substantially spherical tip; (b) a second arm extending from a handle at a proximal end to a distal end having a second substantially spherical tip, the second arm is pivotally connected to the first arm; and (c) an insert removably attachable to the first or second tips. The insert includes a connection mechanism lockingly engaging the first or second spherical tips. Also, the insert includes a first face sized and shaped to be seated over a target portion of skin in an operative configuration. The first face has a first substantially planar portion and a second substantially curved portion attached thereto. The first and second portions define a contour conforming to a contour of skin's target portion.Type: ApplicationFiled: May 14, 2013Publication date: December 26, 2013Applicant: DePuy Synthes Products, LLCInventors: Alberto A.

Patent number: 8597300Abstract: A bone fracture fixation system comprises a bone plate configured to bear against a proximal surface of the bone and a plurality of elongated tension elements, each sized to pass through an opening in the bone plate and through the bone from the proximal surface to a distal surface thereof. Each tension element is anchored to the bone and maintained in tension by a distal anchor attached to said tension element and configured to engage the distal surface of the bone and a proximal anchor engageable between the bone plate and the tension element. In one method for fixation of a bone fracture, the bone plate is positioned on a proximal surface of the bone while the tension element is introduced into the bone and through an opening in the bone plate from an opposite distal surface of the bone.Type: GrantFiled: November 22, 2010Date of Patent: December 3, 2013Assignee: Biomet, C.V.Inventors: Daren L. Deffenbaugh, Dale R. Schulze

Publication number: 20130310885Abstract: The present invention discloses a securing device that is used to secure a fixation device to two bone portions to promote healing between the two bone portions. The bone portions commonly include a skull bone portion and a skull bone flap or implant, and the fixation device is commonly a cranial clamp. The securing device provides for securing the fixation device in a uniform, single movement as opposed to currently available products. The securing device has two handles pivotably connected, and a gripping means moveably associated with one handle. As the handles are activated, the gripping means travels proximally along the one handle and grips an elongated section of the fixation device and exerts a tensioning force along the shaft of the elongated section prior to the cutting means cutting the elongated shaft to secure the fixation device in place.Type: ApplicationFiled: July 22, 2013Publication date: November 21, 2013Inventors: Robert J. Schoutens, Kan Naito, Ulrich Engenhardt, Bruno Wiesmann, Benjamin Straub, Ralf Oesterlein

The first hole encloses a center axis of the second hole and a clearance is provided between the first section and the second section. The assembly includes a screw member having a length for engaging the first hole and the second hole so as to bridge the clearance. The screw member has a first portion with a largest outer diameter smaller than or equal to the smallest diameter of the first hole, and a threaded second portion axially spaced from the first portion and configured to threadedly engage the second hole. A major thread diameter of the second portion is larger than the smallest diameter of the first hole.Type: ApplicationFiled: May 16, 2013Publication date: November 21, 2013Applicant: Stryker Trauma SAInventor: Aaron Forderer
