|20140018828||VARIABLE FRICTION BUCKLE TIGHTENING SYSTEM WITH FRICTION INDICATOR - A method for repairing separated tissues utilises a tissue tensioner including a locking member, a band, a frame, and a restraining member. One end of the band is attached to a first end of the frame. Tension is applied to the band so that it moves freely between spaced engaging surfaces on the locking bar and a second end of the frame, while a restraining member restrains the locking member to a non-engaging position. Application of a predetermined level of tension on the band causes the restraining member to move to a non-restraining orientation, thereby in turn causing the locking member to move so that its engaging surfaces engage the engaging surfaces of the frame, clamping the band. An alarm is triggered to notify a practitioner that the predetermined level of tension has been achieved and that the restraining member has thus moved to the non-restraining orientation.||01-16-2014|
|20140018809||COMPRESSION BONE STAPLE - The present invention relates to devices and techniques for securing bone segments across a fracture site, and more particularly relates to bone staples for achieving compression between segments. A method and apparatus for interosseous bone fixation uses a compression staple, generally U-shaped, having a pair of legs with proximal ends interconnected by a bridge portion that is resilient and bowed, the staple having an initial configuration and capable of a tensioned configuration by spreading apart the legs by a certain amount causing the curvature of the bowed bridge to lessen and the legs to move towards each other with certain compressive spring force.||01-16-2014|
|20140018808||HYBRID MEDICAL DEVICE IMPLANT WITH MIGRATION MANAGEMENT - A dynamic tissue holding device for dynamically holding two tissue portions in contact with one another includes a resilient body having a spring and a band arranged for extending about the tissue portions to be held together. The band has a first end for attachment to a first attachment portion on the resilient body and a second end for attachment to a second attachment portion on the resilient body.||01-16-2014|
|20140018807||LOW FRICTION BUCKLE TIGHTENING SYTEMS AND METHODS - A tensioning device comprises an elongate member, preferably a band, and a frame having first and second sides. The band has a first end that is attachable to the first side of the frame and a second end that is releasably securable to the second side of the frame. A movable clamping member on the frame secures the second end of the band to the second side of the frame by cinching the second end of the band between an engagement surface on the band and a mating engagement surface on the second side of the frame. A restraining member is provided for restraining the clamping member to a first position spaced from the mating locking surface on the second side of the frame, when the restraining member is in a restraining orientation. The restraining member is movable out of the restraining orientation after the band is tensioned to a predetermined level using the second end. The band is tensioned to the aforementioned predetermined level and is secured to the second side of the frame, so that the band establishes a path of tension along its length that extends linearly between the two ends of the band.||01-16-2014|
|20140018804||DYNAMIC TISSUE HOLDING DEVICE WITH LOW PROFILE SPRING - A dynamic tissue holding device is disclosed for dynamically holding two tissue portions in contact with one another. The device comprises a biasing spring having a relatively low profile, and a band adapted for extending about the tissue portions to be held together. The band has a first end for attachment to a first attachment portion on the biasing spring and a second end for attachment to a second attachment portion on the biasing spring. The band establishes a path of tension along its length and extending linearly between the two ends of the band. Advantageously, more than one-half of the biasing spring is disposed outside of the path of tension when the dynamic tissue holding device is in place and holding the two tissue portions together.||01-16-2014|
|20130184720||ACTUATOR FOR BAND TENSIONING SYSTEM - A system for repairing separated body tissues includes a tensioning device having a movable housing, a pair of stationary tensioning tips distal to and attached to the movable housing, and suture tensioning jaws on a proximal end of the movable housing. The tensioning jaws are pivotable between open and closed orientations. A buckle is provided for securing and tensioning suture and the like, having a first plate, a second plate spaced from the first plate so that there is a gap between the first and second plates, and a lock bar within the gap and movable between a first position wherein suture may be freely passed through the gap as tensioning of the suture proceeds, and a second locking position wherein the suture is clamped in place within the gap. A tension tab is provided for securing the lock bar in its first position until tension on the suture exceeds a predetermined level.||07-18-2013|
|20120024937||COMPRESSION BONE STAPLE, APPARATUS AND METHOD OF THE INVENTION - A method and apparatus for interosseous bone fixation uses a compression staple, generally U-shaped, having a pair of legs with sharp front ends and proximal ends interconnect by a bridge portion that is resilient and bowed, the staple having an initial configuration and capable of a tensioned configuration by spreading apart the legs by a certain amount causing the curvature of the bowed bridge to lessen and the legs urged towards each other with certain compressive spring force. A staple applicator supports and guides the staple and positions the tensioned staple with its pointed ends forward, adjacent an ejection port at the front of the applicator. A powered strike member is mounted for longitudinal movement and has a front end that will strike the rear of the tensioned staple with percussive force and eject it in tensioned configuration from the applicator.||02-02-2012|
|20110313435||SUTURE BUCKLE WITH SELECTIVE FRICTION - A tensioning device for holding separated members/tissues in contact with one another. The device comprises a frame having opposing first and second sides and a lower surface and an upper surface, and a band for extending around the separated tissues to be held together in conjunction with the frame. The band has two ends releasably attached to the sides of the frame. When the ends are secured to the sides of the frame, the band establishes a path of tension along its length that extends linearly between the two ends of the band.||12-22-2011|
