摘要： The instrumentation set of this invention assists the surgeon in selecting the proper implant components, in determining the amount of distal bone to resect, and in aligning instrumentation designed to resect the bone. The instrumentation set provides numerous systems for verifying to the surgeon that he has correctly aligned the instruments prior to removing any bone. The set includes a rotational alignment guide, which aids the surgeon in establishing the appropriate rotational alignment for the knee as determined by reference to standard femoral landmarks such as the posterior condyles and epicondyles. The rotational alignment guide includes a slot for guiding a saw blade for removal of the posterior condyles of the femur. The set further includes a tensor designed to tense the knee joint in flexion and extension. The tensor is activated by a torque wrench so that a measured mount of tension force can be applied to the joint. The tensor is configured to slidably carry a sizing rod which contacts the femur and includes a plurality of markings, which relate to the size of the femur as well as the spacing between the femur and tibia. This information is used by the surgeon to select the proper size of femoral and tibial articulate surface components. The sizing rod also indicates to the surgeon any variation required in the amount of bone to be resected.

摘要： Methods and devices for assessing and determining proper alignment and placement of implant components during joint reconstruction surgery, particularly in the knee joint. Provisional components with force transducers 150, 240 are positioned in the joint 40 and used to determine the precise forces and decide how to balance the forces in the joint. In the knee joint, a provisional tibial component 80 and a provisional patella component 85 are used. The tibial component has a base member 84 and a pair of bearing elements 88, 90 held loosely in place by a clamping frame 86. Rocker members 130, 132 allow the bearing elements to move or rock relative to the base member. The patella component has a base plate 220 and a bearing element 222 held loosely in place by a plurality of pins 228. A rocker member 232 allows the bearing element to move or rock relative to the base plate. Force transducers or sensors 150, 240 connected to computers are positioned in the provisional components 80, 85 and provide readings of the location and magnitude of the sum of the forces generated in the joint when the joint is moved through its range of motion.

摘要： A method for manufacturing an static random access memory (SRAM) cell (10) begins by manufacturing a fuse region (36) over a substrate (10). An etch stop layer (44) is formed overlying the fuse region (36) from resistor polysilicon material. In order for the fuse region (36) to be accessed and properly disabled, an opening (60) must be provided which stops on the etch stop layer (44). The etch stop (44) ensures a consistent and repeatable optimal thickness X of dielectric material above the fuse region (36) to provide for proper laser access and repair. The etch stop layer (44) therefore reduces wafer to wafer and die to die variation in thickness X and provides for a higher yield laser repair for each SRAM integrated circuit and every wafer processed using this methodology.

摘要： A set of distal femoral knee prostheses which are designed to be more narrow in medial/lateral dimensions with increasing anterior/posterior size than existing prostheses to more closely correspond to the physical anatomy of female patients. The prostheses are designed to have a substantially trapezoidal shape or profile when viewed distally which features a more pronounced narrowing of the medial/lateral dimensions beginning at the posterior end of the prostheses and progressing anteriorly to the anterior end of the prostheses. Additionally, the prostheses each include a reduced profile patellar sulcus and reduced profile anterior condyles to more closely conform to the anatomy of a resected femur, and also include sulcus tracking optimized to conform to female anatomy.

摘要： The invention herein describe reduces the concerns associated with the use of intramedullary instrumentation by providing for the reduction of pressure within the medullary canal as the intramedullary instrument is inserted. Specifically, in the preferred embodiment a sleeve having a proximal end connected to a vacuum source is fitted over the intramedullary rod so that as the rod is inserted into the intramedullary canal, the pressure within the canal is reduced to thereby reduce the magnitude of cells released into the blood stream. In order to draw air from the medullary canal, the proximal end of the sleeve includes a gasket which seal against the intramedullary rod causing the air to be drawn only from the distal end of the sleeve. In an alternative embodiment, an air passage is provided directly through the instrument with the exposed end of the instrument being connected to a vacuum source.
