Abstract: A bone stent facilitates bone fixation via interior contact, as may be useful for flexible entry into a sidewall of an elongated bone. As consistent with one or more embodiments, a stent includes proximal and distal end caps connected by a plurality of elongated members extending longitudinally between the end caps, and a flexible cable extending through the proximal end cap and connected to one of the end caps. The flexible cable, end caps and elongated members are responsive to the end caps being moved toward one another by laterally bending the elongated members outwardly away from one another, with the cable fixing the elongated members in the compressed state (e.g., while applying pressure to the interior sidewalls of a bone). When the end caps are released from the compressed state, the longitudinal compressive force is released and the elongated members elastically return to the uncompressed state.

Abstract: The Intramedullary Nail System including Tang-deployment Screw with Male Interface includes a nail for insertion into the intramedullary canal of the femur and a lag screw for insertion through the nail, into the femoral head of the femur. The nail is held within the intramedullary canal of the femur, affixed internally by the lag screw and tangs, without the use of screws that penetrate the surface of the bone, and without requiring significant x-ray exposure. For nails of small diameter, a coupler, with two female ends, allows the diameter of the male/female interface between the driver and the actuator, which in turn extends the tangs, to be increased. This increase is possible because the lower section of the nail, where the talons are stored prior to extension, is of a larger diameter than the remainder of the nail.
