摘要： A surgical staple including at least one deformable member which can be bent upon contacting an anvil of a surgical stapler. In various embodiments, at least a portion of the deformable member can include a non-circular cross-section which can dictate the direction and manner in which the deformable member is bent. In at least one various embodiment, the non-circular cross-section can include a flat portion which can cause the deformable member to bend in the direction of the flat portion. In various embodiments, the non-circular portion of the cross-section can be configured to abut soft tissue of a patient and apply a compressive force or pressure thereto. In various embodiments, a crown formed on the surgical staple can dissolve as the soft tissue heals and can, depending on the cross-sectional geometry of the deformable member, reduce the force or pressure applied to the soft tissue by the deformable member.

摘要： A clip, clip applier and method for ligating a tissue structure is provided. The applier has a two stage actuation. In the first stage, a tissue structure is positioned into the jaws of the clip applier. The jaws close and lock to a preset force to compress and temporarily occlude the tissue structure. If satisfactorily positioned, the second stage is initiated in which a clip is advanced through the shaft of the clip applier in a closed position. At the distal end of the clip applier, the clip is opened slightly to capture the pre-compressed tissue structure, and is placed over the structure. The clip is then dissociated from the business end of the instrument. Preferably the clip comprises two leg members disposed in close proximity to one another joined from opposing directions by a connecting element. The connecting element restricts separation of the leg members with opposing spring members so as to provide substantially uniform parallel deflection of the leg members from each other.

摘要： A multi-patient use trocar assembly is disclosed. The trocar assembly has obturator and cannula subassemblies. The obturator subassembly has an elongated obturator shaft which can receive an endoscope at its distal end. The obturator shaft is reusable for multi-patient use. A transparent obturator tip is detachably mounted onto the end of the obturator shaft. The obturator tip is transparent and disposable. Because it is transparent, illuminated images provided by the endoscope within the body cavity can be transmitted through the obturator tip. Once the trocar assembly is used on a first patient, the obturator tip is detached and disposed of, and replaced with another obturator tip. Hospital costs are reduced because the trocar assembly can be reused multiple times, and only the obturator tip needs to be disposed of after each patient use.

摘要： A staggered bitline sense amplifier architecture utilizes a circuit to simulate the effect of a memory cell on each of the edge sense amplifiers not selected for connection to an activated memory cell, thereby to allow the edge sense amplifiers to be activated simultaneously with the sense amplifiers internal to the memory array without the danger of burning out the edge sense amplifiers. This structure eliminates the address decoding circuitry commonly associated with the edge sense amplifiers used in staggered shared bitline sense amplifier architectures, thereby decreasing the complexity and reducing the chip size of such memory arrays.

摘要： A serial address generator for a sequential (burst mode) random access memory generates a sequence of internally generated addresses for fast cycling. The start address is externally provided. Then, as the clock signals arrive, the subsequent addresses are generated in sequence by the address sequencer. The address sequencer is preset to the second address in the sequence following the start address. Simultaneously, the start address is connected by an external address enable switch to an output terminal of the address generator, bypassing the address sequencer. When the first clock signal arrives at the address sequencer, the address sequencer output is sampled by closing an internal address enable switch and opening the external address enable switch. Thus the internally generated addresses are provided immediately following the start address. The address sequencer thereby generates each address one clock cycle ahead of that in the prior art, and the output address is provided one half clock cycle ahead of that in the prior art.

摘要： A surgical stapler having a trigger attached to a ratcheting mechanism for preventing the refiring of the stapler trigger with a staple loaded within a forming mechanism. In addition, the mechanism contains driver buffering means to prevent the sharp reduction in opposing force driving formation of a staple. The staples are constantly maintained in proper orientation during transfer from a track to the forming site, and are self-centering on the former, and have an oversized crown so that cold-worked areas on each staple do not hinder forming.

摘要： An endoscopic clip applying system as described which contains a venting system and a clip applying support system which prevents closure of the mechanism before firing. The applier's jaws are spaced apart no further than the width of the applier shaft, even when holding a clip. Also, the system ensures proper loading of the clips and prevents them from falling out during loading. Further, the system describes an easily manufacturable, positively opening system which has minimized size requirements. Furthermore, a lock-out mechanism is provided so that the mechanism may not be inadvertently fired. The shaft resists excessive torque as well as holds the clip in place during firing. There are provisions for sealant and non back-up of the clips, as well as features which make the clip properly placed for closure. In an alternate embodiment, the clip applier shaft rotates about its handle mechanism.

摘要： An improved process for treating spent alkylation acid to recover a sulfuric acid product suitable for use in wet process phosphoric plants particularly those which recover uranium as a byproduct. The process utilizes heat and agitation to polymerize the liquid, soluble organic impurities normally contained in spent alkylation acid to insoluble, carbonaceous solids. The carbonaceous solids formed are relatively inert in acidic environments, easy to handle and have valuable cation exchange and impurity scavenging properties.

摘要： A process for producing high grade silica and fluorine-containing coproducts from fluosilicic acid is described. To produce silica, the fluosilicic acid is reacted with aqueous ammonia to produce a solid silica product and a solution of ammonium fluoride. The solid silica is washed under controlled conditions and further processed to produce a high grade product. The ammonium fluoride solution is concentrated and sold as a concentrated ammonium fluoride solution product or reacted with metal hydoxides or oxides to produce metal fluorides.

摘要： A flexible positioning tab is provided for placement in the staple forming track of skin staplers. This flexible tab causes only one staple from a staple stack to be moved into a staple stack for forming the staple at an anvil forming surface. This prevents the skin stapler from jamming multiple staples in the staple forming track.
