Abstract:
1. An implantable fixation assembly for removably securing a medical device in a human body, the assembly comprising: an anchor portion having a plurality of holes, the holes facilitating attachment of the anchor portion to bone; a body attached to the anchor portion, the body having a pair of spaced apart legs, at least one leg being resiliently flexible, each leg having a distal end; a clamp portion attached towards or at the distal ends of the legs; a screw and nut combination having an axis of rotation longitudinal to the legs and comprising a driving member formed by said nut at an end of a shaft of the screw and which abuts an outer side of a distal end of the legs so as to produce a wedging action that induces a lateral force that pushes the legs together as the shaft is rotated so as to cause the driving member to be driven longitudinally with respect to the legs thereby actuating the clamp portion to secure the device, wherein the screw has a head, the head shaped to receive a driver, whereby a surgeon can selectively grip and release the device using the driver, movement of the driving member being reversible so as to release said lateral force and allow said legs to move apart due to the resilience of said at least one resiliently flexible leg for selectively releasing the device, wherein said anchor portion comprises an arm and extensions extending therefrom, and wherein said body is attached to the arm.
