Abstract: The present disclosure provides a femoral cut guide for preparing a distal femur to receive a prosthetic femoral component of a knee implant. The prosthetic femoral component includes a central box. The femoral cut guide replicates the size and shape of the prosthetic femoral component, such that the femoral cut guide may serve as a trial or provisional component used to reduce and test the prepared knee joint before implanting the final prosthetic femoral component. The femoral cut guide includes a detachable box cut guide for preparing the distal femur to receive the central box of the prosthetic femoral component.

Abstract: A hip stem centralizer datum guide and method are provided for positioning a proximal portion of a hip stem component within bone cement in an intramedullary canal of a femur. The datum guide is positionable in a predetermined position relative to the intramedullary canal and is able to create a datum that records the predetermined hip stem component position relative to the intramedullary canal. The datum is able to be referenced to position the hip stem component in the predetermined hip stem component position in the bone cement in the intramedullary canal.

Abstract: The invention is yarn, fiber, film or tape composed of a compatibilized blend of polyester and polyamide resins, with improved fibrillation and abrasion resistance, and an industrial fabric produced thereof. The blend uses carbodiimide (CDI) compound containing at least two carbodiimide groups in the molecule as a compatibilizing agent. A unique, high modulus, dimensionally stable and abrasion resistant yarn, fiber, film or tape is created as a result of the combination of the polyester and polyamide with CDI in a preferred proportion.

Abstract: A hip stem centralizer datum guide (40, 100, 200, 300) and method are provided for positioning a proximal portion of a hip stem component (44) within bone cement in an intramedullary canal of a femur. The datum guide is positionable in a predetermined position relative to the intramedullary canal and is able to create a datum (70, 72, 74, 76, 120, 220, 302) that records the predetermined hip stem component position relative to the intramedullary canal. The datum is able to be referenced to position the hip stem component in the predetermined hip stem component position in the bone cement in the intramedullary canal.

Abstract: A surgical instrument having a grip, a reference structure and an alignment head and method of using. The reference structure has at least one reference element that is registrable in a computer assisted navigation system. The reference element may be a reflective structure for use in an optical tracking system, wire loop for sensing a magnetic field, or other suitable device. The alignment head has a substantially planar alignment surface and may also have a plurality of outwardly extending projections or an electrocautery electrode disposed along an edge of the alignment surface and extending parallel to the alignment surface. The projections may be engaged with an anatomical structure to hold the alignment head in a desired position as the alignment surface is used as a guide to mark the anatomical structure. The disclosed instrument may be used when resecting a femur to prepare the femur to receive the femoral component of a prosthetic hip joint.

Abstract: An in situ cleaning system is disclosed for use with semiconductor processing equipment. In accordance with an important aspect of the invention, the cleaning system provides for dynamic cleaning of the semiconductor processing system by varying the pressure of the cleaning gas over time during a cleaning cycle. In particular, the cleaning gas is applied to the semiconductor processing system in repeated pressure cycles. Each pressure cycle begins with the pressure of the cleaning gas at PMIN. The pressure of the cleaning gas is increased to a maximum pressure PMAX during a fill portion of the pressure cycle and maintained for a dwell time selected to allow the available reactants to generate the desired end products. The pressure in the chamber to be cleaned is then reduced during a vent portion of the pressure cycle to permit venting of the reaction products.

Abstract: A hip stem centralizer and method are provided for positioning a proximal portion of a femoral hip stem component at a desired radial position within an intramedullary canal of a femur. The hip stem centralizer includes a resilient opening that is elastically compressed upon receiving the hip stem to bias the hip stem to a desired position in the intramedullary canal.

Abstract: An acetabular cup kit for use during hip replacement surgery includes a polar component with a socket for receiving a femoral head of a femoral prosthesis. A metal shell has a cavity which is configured for receiving the polar component therein. The metal shell also includes an annular face bounding the cavity. A metal ring is attachable with the metal shell at the annular face. The metal ring is configured to retain the polar component within the cavity when attached with the metal shell. The metal ring includes at least one secondary fixation device, such as a flange, allowing fixation of the metal ring with a pelvic bone. A plastic ring is also attachable with the metal shell at the annular face. The plastic ring is configured to retain the polar component within the cavity when attached with the metal shell.

Abstract: A milling instrument for use in orthopaedic surgery includes an elongate stem for insertion into a prepared intramedullary canal of a bone. A pivotable mill includes a base connected to the stem and a cutting head pivotally connected to the base about a pivot axis. The cutting head has an axis of rotation and is rotatable about the axis of rotation. The cutting head has a first abutment surface positioned relative to the pivot axis and the base has a second abutment surface positioned relative to the pivot axis. The first abutment surface and the second abutment surface abut each other upon pivoting of the cutting head relative to the base at a predetermined angle and thereby limit the pivoting therebetween.

Abstract: An apparatus and method for harvesting a tendon graft beneath the overlying tissues through a remote incision which exposes only a portion of the donor tendon from which the graft will be harvested. The apparatus or tendon harvester 10 includes an elongated tubular shaft 20 connected to a cylindrical handle 30 and a length of flexible cutting wire or cable 12. A needle 16 is connected to one end of the cable 12 which extends from the distal end of the shaft 20. The needle end of the cable 12 is affixed to the distal end of the shaft 20 to form a cable loop for slitting the tendon 4.

Abstract: This invention includes a ratchet wheel carried by the locking bolt and engaged by a pin carried by the targeting guide. The pin and ratchet wheel permit the locking bolt to rotate in a tightening direction and prevent the bolt from rotating in a direction to cause the bolt to loosen. Therefore, during impact, the bolt is prevented from loosening. After the IM rod is inserted and the surgeon wants to remove the targeting guide, the pin is shifted and locked into a disengaged position with the ratchet wheel to permit the locking bolt to rotate without obstruction. The ratchet pin may be locked in its retracted position.

Abstract: The targeting device of this invention includes a radio-transparent handle and a metal snap fit barrel. The radio-transparent handle reduces obstructions in the radio-graphic image to provide a clearer image to the surgeon for proper placement of the locking screws. The metal snap fit barrel is retained in the handle by an interference fit between the handle and biased keys carried by the barrel. After use, the barrel may be easily disassembled for cleaning by striking a removal tool against the keys to drive the barrel from the handle.
