The present invention utilizes a split hub assembly that provides the user two modes of operation, unipedal or bipedal. Unipedal mode is when each crank is functioning independent of the other thus forcing the user to work each leg differently yet simultaneously. Bipedal simulates the normal operation of a bicycle. In the preferred embodiment, each side of the invention (left and right side for left and right legs) has its own drive system. The split hub assembly is housed between each drive system, and by using an actuator, the drive systems can be connected to provide bipedal operation, or disconnected to provide unipedal operation. This allows each side, in unipedal mode, to vary its resistance without affecting the other side in order for a patient to exercise both legs separately and favor one with a different resistance to account for an injury or recovery from surgery. The friction brakes for each drive system are controlled by a microprocessor that turns the motors in the required direction for either increasing or decreasing the tension on the brake belt. The microprocessor monitors power and performance and regulates the resistance levels to deliver either isotonic or isokinetic resistance. The resistance in bipedal mode is varied in the same manner, but the resistance is equal on each leg.

Unipedal cycle apparatus

Apparatus for tensioning a ligament graft includes a hydraulic tensioning cylinder with a piston having a distal end for holding and affixing, relative to the distal end of the piston, a free end of a ligament graft, where the other end of the ligament graft is affixed to a patient. An inflation device, in hydraulic communication with a cylinder, moves the piston to tension the graft.

System for tensioning ligament grafts

A suture locking fastener for surgical procedures. The one piece plastic molded fastener features a plurality of triangular-shaped leaves that are attached to a base. At least one of the leaves is attached to the base using a flexible hinge section thus permitting that leaf to articulate with respect to the base. The leaves are positioned at a predetermined angle relative to the horizontal that is at least 30 degrees, and, preferably, 45 degrees which permits a suture, either a thread or a plastic filament, to be held securely without deforming or cutting into it.
