Abstract: A system includes a tubing set and a drive assembly. The tubing set includes inlet tubing couplable to a source of fluid, a valve coupled to the inlet tubing, a syringe coupled to the inlet tubing via the valve, and outlet tubing coupled to the valve. The valve is configured to allow fluid to be drawn from the source of fluid via the inlet tubing into a syringe body of the syringe and to be expelled from the syringe body and through the outlet tubing, and to prevent fluid from being drawn from the outlet tubing into the syringe body and to prevent fluid expelled from the syringe body from flowing through the inlet tubing. The drive assembly is configured to reversibly receive the tubing set such that a drive mechanism is engaged with a plunger of the syringe to reciprocally translate the plunger relative to the syringe body.

Abstract: A surgical appliance for assisting in the repair of a fractured bone, such as a scaphoid bone, is disclosed. The device includes first and second adjustably interconnected and spaced apart limb clamping jaws that are transparent to x-ray radiation and are relatively movable toward and away from one another and a rotatable disk carried by the first jaw, said disk having a plurality of bores angularly disposed in the disk for selectively aligning a guide wire to be drilled percutaneously into the fractured bone. Each of the bores are in communication with the space between the first and second jaws and the longitudinal axes of said bores are directed to a common point intermediate the first and second jaws.

Abstract: A method and associated apparatus for percutaneous internal fixing of a fractured limb bone comprising, placing the limb in a stabilizing clamp that is transparent to x-ray radiation, demonstrating the fractured bone to be fixed, resolving the course through the fractured bone of an intended fixation device, inserting a guide wire along the resolved course and across the fracture faces of the bone through an alignment conduit in the stabilizing clamp, drilling a pilot hole in the bone through the fracture faces by directing a cannular drill over the guide wire, and introducing a cannular fastening screw within the drilled pilot hole and across the bone fracture site to achieve apposition of the fracture fragments of the bone.

Abstract: A method and apparatus for percutaneous internal fixing of a fractured limb bone including, placing the limb in a stabilizing clamp, demonstrating the fractured bone to be fixed, resolving the course through the fractured bone of an intended fixation device, placing a guide wire through exterior and interior tissue adjacent the fractured bone and along the resolved course and across the fracture faces of the bone, incising the tissue proximate the guide wire, spreading the tissue proximate the guide wire to provide space for a drill bit and a surgical screw in the area surrounding the guide wire, drilling a hole in the bone through the fracture faces by directing a cannulated drill over the guide wire, and installing a cannulated fastening screw within the drilled hole and across the bone fracture site to achieve apposition of the fracture fragments of the bone.

Abstract: A hip joint prosthesis comprising a femoral stem, adapted for implant into the medullary canal of a human leg femur, said stem having a superior neck portion whose longitudinal axis is arcuate, forming concave and convex portions thereof, and terminating in a globular femoral head, and an acetabular cup, adapted to be attached to a human pelvis. The cup is sized and shaped to rotatingly receive the femoral head. The inferior portion of the cup is relieved by an indentation therein which accommodates the convex contour of the arcuate neck during extension and abduction of the leg. The concave portion of the neck is adapted to arch over and avoid interfering with the superior rim of the cup during hyperflexion of the leg. The indentation in the inferior portion of the cup is intended to receive and accommodate the convex contour of the arcuate neck during extension and abduction of the leg.

Abstract: A joint for a hip brace or prosthetic which allows adjustable degrees of pivoting of the leg, rotation of the leg and abduction/adduction of the leg.

Abstract: The present invention relates to method and apparatus for implanting and cementing the femoral stem component of a hip prosthesis. The process includes the steps of resecting the femoral neck, reaming a bore into the proximal medullary canal, enlarging that bore to accommodate the elongated stem of the femoral component, including the greater enlargement of the portion of the bore adjacent the transverse plane of the neck resection, establishing a peripheral shoulder in the cancellous bone of the medullary canal to seat a sealing plug, installing on the seat a perforable sealing plug, injecting the cavity with cement and implanting the femoral stem in the enlarged bore of the medullary canal by puncturing the sealing plug with the distal end of the stem and moving the stem distally further so that the sealing plug becomes a collar around the stem intermediate its ends.
