Assignee:
St. Francis Medical Technologies, Inc. - Alameda CA
International Classification:
A61F 2/44
US Classification:
623017110
Abstract:
Systems in accordance with embodiments of the present invention can include an implant comprising a spacer for defining a minimum space between adjacent spinous processes, a distraction guide for piercing and distracting an interspinous ligament during implantation, and a binder for limiting or preventing flexion motion of the targeted motion segment. The binder can be secured to a brace associated with the implant during implantation by a capture device. In one embodiment, the capture device includes a fixed piece extending from the brace and a slidable piece associated with the fixed piece. A fastener can be rotated to pinch the binder between the slidable piece and a wall of the brace, securing the binder. A physician need not know the length of the binder prior to implantation, reducing the time required to perform a procedure.

International Classification:
A61B 17/70
US Classification:
606248, 606249
Abstract:
Systems and method in accordance with embodiments of the present invention can includes an implant having an initiating piece and a distraction piece. The initiating piece can include a lower distraction element, a second wing, a lower portion of a spacer, and a lower portion of a first wing. The initiating piece can be positioned such that an interspinous ligament of the targeted motion segment is disposed between the first and second wing. The distraction piece can include an upper distraction element, an upper portion of the spacer, and an upper portion of the first wing, and can be mated with the initiating piece by mating a rail of the distraction piece with a slot of the initiating piece, thereby disposing the implant between adjacent spinous processes.

International Classification:
A61B 17/70, A61F 2/44
US Classification:
623 1711, 606248, 606249
Abstract:
Systems and method in accordance with an embodiment of the present invention can includes an implant comprising a spacer and a frame having a central body and a helical shaped wing extending from the central body. The frame can be positioned near about adjacent spinous processes, and can be rotated and urged so that the adjacent spinous processes pass within a groove of the wing, thereby allowing the wing to be arranged on an opposite side of the adjacent spinous processes. The spacer can then be arranged over the frame so that the spacer contacts and distracts the spinous processes, thereby limiting relative movement of the adjacent spinous processes during extension.
