摘要： The invention is directed to a pair of laparoscopic scissors, comprising a pair of blades connected at a pivot, each of the blades having a length, a tip portion, a body portion, an outer surface, an inner surface and a cutting edge, the cutting edge forming an angle with the outer surface along the length of the blade such that tension during a cutting operation at the tip portion is about the same as tension at the body portion during the cutting operation. The angle formed may be greater at the tip portion which continuously decreases over the length of the blade. The tip portion may have a first body thickness and the body portion may have a second body thickness different from the first body thickness. During the cutting operation, the blades progressively move over each other to provide a point contact along the cutting edges. The blades may be thickened in a number of locations and combinations including: (1) one blade could be thicker than the other to force the opposing blade to flex; (2) both blades could be thicker at the body portions to give more strength when cutting staples; (3) each blade could be thickened on one side or the other to stiffen certain locations; and (4) the tips of each blade could be thicker than the body portions to provide increased tension at the tips. In another aspect of the invention, a process of manufacturing the pair of scissors of the invention is disclosed, comprising the steps of form grinding the blades into a desired shape from a pre-hardened block of material, and sharpening the cutting edges of the blades. The blades may also be formed through other processes including wire EDM, laser cutting, waterjet cutting, machining, cast or metal injection molding, and other independent profile manufacturing processes. The manufacturing process of the invention is beneficial in that each profile can be accurately controlled, and the parts will be exact every time.

摘要： The determination of human serum albumin (HSA) in urine is carried out by contacting the urine with a reagent system containing a buffer and a protein error indicator. Other proteins normally found in urine can compete with the HSA for interaction with the protein error indicator thereby affecting the sensitivity of the test for HSA. The present invention involves the addition of certain polymeric competitive inhibitors to the reagent system which inhibit the interaction of the urinary proteins other than HSA with the protein error indicator to a greater extent than the interaction with HSA is inhibited thereby increasing the reagent's sensitivity for HSA. Suitable polymeric inhibitors include poly(vinyl alkyl esters), poly(alkyl acrylates), poly(vinyl alkyl carbonates) and poly(vinyl alkyl ketones).

摘要： A surgical clamping device includes a first jaw and a second jaw movable relative to the first jaw between the proximal position and a spaced position. The first jaw has a supporting surface facing toward the second jaw and an opposing surface facing away from the second jaw. An insert is removably mountable in an operative position on the first jaw and includes an insert base having a central wall and a pair of side walls which form a channel configured to receive the first jaw. An elastomeric material forms a pad on the central wall facing the second jaw while the side walls extend away from the second jaw. Holes in the central wall increase the thickness of the pad without increasing the profile of the insert. A detent mechanism extends laterally of the first jaw between the supporting surface and the opposing surface of the first jaw without interfering with the structural integrity of the clamping device.

摘要： One aspect of this invention relates to a temporary heart wire, and external connector therefore, and the combination of the two, wherein the distal end of the heart wire includes a temporary affixation coil (8) and distal pacing (2) and sensing (1) electrodes connected by means of a coaxial helicoidally wound cable (3) to a proximal electrode (7) and a breakaway needle (6) which also serves as a proximal electrode. The lead is adapted to be inserted into a disposable connector having a snap aperture element (19) for receiving the breakaway needle, and about which the needle is broken, as well as electrical contacts (17, 18) for contacting the proximal electrodes and adapted to be connected to a temporary external pacemaker. According to another aspect of this invention, there is provided a permanent bipolar nerve electrode which includes two electrodes (52), (54) adapted to be positioned along the nerve trunk (58). The bipolar nerve electrode further includes an affixation coil (56) and a thin insulation layer or flap (57), this latter being adapted to be sutured to the surface of the patient's muscle to thereby preclude or limit stimulating electrical energy to be transmitted to adjacent muscles, this allowing for a more focused concentration of electrical energy to the nerve trunk (58) to be stimulated.

摘要： A memory array (e.g., DRAM) is provided with a potential maintenance circuit which provides sufficient current to maintain a high potential node of the memory array at a predetermined potential. The potential maintenance circuit is gated ON after receipt of a clock signal and gated OFF at the predetermined potential. This permits the high voltage node to be maintained, while reducing current requirements. The invention is particularly useful when used in conjunction with a circuit which rapidly pulls up the high node to a value of V.sub.CC -V.sub.T (where VT is a threshold voltage of a transistor).
