Assignee:

International Classification:

A61B 17/04
A61B 17/12

US Classification:

606144

Abstract:

In repairing soft tissue with a bone anchoring instrument (such as reattaching a tendon of a torn rotator cuff), the bone anchoring instrument may be used to anchor the soft tissue to a region of bone. The anchors inserted into the underlying bone may have one or more lengths of suture or wire attached thereto which may be tensioned independently of one another to affix the soft tissue to the bone by having a selector mechanism selectively engage and disengage ratcheted tensioning wheels from one another. Suture loading mechanisms may be employed for passing suture lengths into and/or through the anchors prior to deployment into the bone where such mechanisms may employ suture snares which are configured to reconfigure from an expanded shape through which suture lengths may be easily passed to a low-profile shape which secures the suture lengths within the snare.

International Classification:

A61B 17/04

US Classification:

606232

Abstract:

A knotless bone anchor and method for securing soft tissue, such as tendons, to bone, includes a plurality of discrete components. In one variation of the invention, the bone anchor includes a proximal toggle component, an intermediate plug component, and a distal sleeve component. Suture is looped around the plug component and once the anchor is actuated, the suture is compressed between the plug and the sleeve components. Advantageously, one or more of the components may be made of a biocompatible polymer. The polymeric components may be detachably joined to a drive shaft using a plurality of sacrificial fills. The sacrificial fills are broken or severed during deployment of the anchor. Related instruments and methods are also described.

International Classification:

A61B 17/82
A61B 17/56

US Classification:

606 74

Abstract:

A surgical tensioning device for holding separated tissues in contact with one another. The device comprises a frame having two opposing first and second sides and a lower surface and an upper surface, and a band for extending around said separated tissues to be held together in conjunction with said frame. The band has two ends attached to the sides of the frame releasably. 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.

Inventors:

Seth Arnold Foerster - San Clemente CA, US
David Trottingwolf Aldridge - Laguna Hills CA, US

Assignee:

DALLEN MEDICAL, INC. - San Clemente CA

International Classification:

A61B 17/82

US Classification:

606 74

Abstract:

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.
