摘要： A novel method for replacing a previously implanted knee joint prosthesis in a patient is disclosed in which the previously implanted femoral component is replaced with a revision femoral component having thicker distal and posterior bearing portions so as to restore the natural anatomic transverse joint plane and collateral ligamentous balance in extension and flexion of the prosthetic joint. Instrumentation for use in this method includes a novel revision cutting jig which is used in the preparation of the distal end of the femur for the implantation of the revision femoral component.

摘要： The bone prosthesis of the present invention comprises a first body member or stem for placement into a bone cavity, such as an intramedullary canal. The body member is configured and dimensioned so as to provide a nonuniform interference press-fit. The apparatus further comprises a second body member or broach for placement into the broach configured and dimensioned so as to prepare and removal from a bone cavity, the bone cavity so as to provide a nonuniform interference press-fit with the stem. THe apparatus further comprises a distal sleeve configured and dimensioned so as to be attached to the stem so as to centralize the stem in the bone cavity. The distal sleeve preferably is provided with an interior conical slope and an exterior conical slope on a portion thereof to aid in insertion into the canal. The stem further comprises at least one groove and preferably a plurality of grooves along its corners. These grooves are nonparallel to the longitudinal axis of the stem and do not extend over any one entire side of the stem. The stem can be provided with an area of cancellous texture which comprises substantially randomly patterned array of multiple curved-line surface unevenness, such as indentations or protrusions. The present invention also is directed to a method comprising utilization of the broach, the stem and the distal sleeve so as to provide a nonuniform press-fit between the bone prosthesis and the bone cavity while centralizing the stem in the bone cavity.

摘要： An invasive, fluid velocity measuring wire guide particularly adapted and of a size (less than 0.030 inch) for subselective placement in the coronary arterial tree, which includes a Doppler mechanism for determining the blood flow velocity in the region of the distal end of the wire guide. Although the wire guide is particularly adapted for diagnosing coronary arterial disease subselectively; it is of such a size and manipulability to be useful in other blood flow and biological fluid flow analyses. Preferably, the wire guide is flexible and steerable for precise placement. The wire guide includes an elongated wire member having a Doppler crystal attached in longitudinal alignment at its distal end. Electrical leads extend from the Doppler crystal along the wire member to the appropriate test equipment for measuring the fluid flow velocity in the region of the Doppler crystal. Preferred embodiments of the Doppler means include piezoelectric crystals and piezoelectric polymers. Also disclosed is a guide wire with a laser Doppler means.

摘要： A proximal femoral sealing device is disclosed for use in the application of bone cement under pressure to a surgically prepared medullary canal of a femur prior to the implantation of a hip prostesis. The proximal femoral sealing device is formed of a generally solid body member with a passageway and a flexible annular wall member extending from the body member. The sealing device has an anatomically shaped outer surface, corresponding to the exposed endosteal surface of a prepared medullary canal. A chamber defined by a flexible annular wall and the body member opens into the medullary canal. In turn, the passageway communicates with the chamber and permits insertion of a cement nozzle therethrough into the chamber. In operation, the proximal femoral sealing device is placed within the proximal end of a surgically prepared medullary canal. The canal and chamber of the sealing device are filled with cement resulting in the expansion of the flexible annular wall member against the exposed endosteal walls of the medullary canal by cement pressure within the chamber thereby forming a pressure seal. The escape of cement through the open end of the excavated medullary canal is prevented via this pressure seal insuring that the applied cement is properly pressurized and that the medullary canal is prepared for implementation of the prosthetic device. A method of providing cement under pressure to the exposed endosteal surface of a medullary canal is also disclosed using this proximal femoral sealing device.

摘要： Devices and methods for transmitting neural signals from a proximal stump of a transected nerve to a prosthetic apparatus are disclosed employing microelectrodes, preferably conductive fiber networks, capable of sensing electrical signals from a nerve and transmitting such signals to a prosthetic apparatus; and a semipermeable guidance channel disposed about the microelectrodes. The channels include an opening adapted to receive the proximal stump of a transected nerve, such that the channel promotes the growth of the stump and the formation of an electrical connection between the transected nerve and the microelectrode.

摘要： A novel prosthesis for use in repairing or replacing soft tissue is disclosed, which comprises a triaxially-braided fabric element having interwoven first, second and third sets of fibers, with the fibers of the second and third sets being oriented at substantially the same acute braiding angle with respect to the fibers of the first set. An elongated ligament prosthesis exhibiting the desired properties of high strength and high elasticity may be prepared by selecting high elasticity fibers for the first set, orienting said first set of fibers in the longitudinal direction of the prosthesis and selecting fibers having high yield strength and high Young's modulus for the second and third sets. A tubular prosthesis in which high elasticity fibers are oriented in the longitudinal direction is highly suitable for use as a vascular prosthesis. A prosthesis of the invention may also be manufactured in the form of a prosthetic heart valve leaflet.

摘要： An adjustable housing suitable to be used with another housing and with a synthetic ligament so as to provide (for example) an anterior cruciate ligament prosthesis system for a knee joint is provided. The adjustable housing features an interior having a step shoulder located therein. A set screw in the housing fixes the synthetic ligament at a desired level of tension. The system has many significant advantages including (but not limited to) being able to withstand very high loads and being able to be retensioned repeatedly and easily without replacing the artificial ligament.

摘要： A method of producing a site for tissue ingrowth on a surgical implant by embedding a space occupier possessing a desired pattern in the surface of the implant at the desired location for ingrowth and then solubilizing the embedded space occupier to leave the pattern on the implant surface. Preferably, the implant is fabricated from a composite comprising a semi-crystalline thermoplastic resin such as polyetheretherketone or polyphenylene sulfide, and the space occupier is an acid-soluble metal plate machined to produce the desired pattern and removed by aqueous acid solution.
