摘要： An anvil and driver assembly for a surgical skin stapling instrument producing formed and implanted skin staples of more consistant and perfect configuration. The anvil provides an anvil surface which supports the crown of the staple during the forming operation. The driver has an inverted U-shaped notch formed therein which defines parallel side edges to bend the staple legs about the anvil and a transverse edge joining the side edges and adapted to contact the crown of the staple near the end of the forming operation. In the anvil and driver assembly of the present invention, the clearance between the parallel bending edges of the driver and the adjacent anvil edges is greater than the transverse dimension of the staple wire. The anvil surface of the anvil is concave and the crown contacting edge of the driver is so configured as to impart a temporary bow in the staple crown near the bottom of the driver stroke, which bow is of such dimension as to preclude plastic deformation of the crown. This produces a more generous bend and a slight over-bend at the junctures of the staple legs and the crown such that when the crown is released by the driver and returns to its rectilinear state, this action of the crown will compensate for the natural spring-back properties of the material from which the staple is made at the above noted junctures, consistantly producing the desired final formed configuration of the staple.

摘要： An obturator as part of a biopsy system enhances use with Magnetic Resonance Imaging (MRI) by indicating location of a side aperture in an encompassing cannula. The cannula (e.g., detached probe, sleeve sized to receive a core biopsy probe) includes a side aperture for taking a tissue sample. When the obturator is inserted in lieu of the biopsy device into the cannula, a notch formed in a shaft of the obturator corresponds to the side aperture. A dugout trough into the notch may further accept aqueous material to further accentuate the side aperture. In addition, a series of dimensionally varied apertures (e.g., wells, slats) that communicate through a lateral surface of the shaft and that are proximal to the side aperture receive an aqueous material to accentuate visibility in an MRI image, even in a skewed MRI slice through the cannula/obturator.

摘要： A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied so as to apply various clamping forces and pressures to soft tissue captured within the staples. In at least one embodiment, the staples can include crowns formed thereon which can be utilized to adjust or control the clamping force and/or pressure applied by the staples.

摘要： A surgical staple including a crown comprised of a dissolvable, bioabsorbable, or biofragmentable material, a first deformable member, and a second member. In at least one embodiment, the crown connects the first member and the second member, however, after the crown has been dissolved, the first member is unconnected to the second member and, as a result, the first and second members can move relative to each other. Accordingly, the staple can be rigid during the early stages of healing and can be flexible during the latter stages of healing, for example. In various embodiments, the first and second members of the staple are also comprised of a dissolvable, bioabsorbable, or biofragmentable material. In these embodiments, the first and second members can be constructed so that the crown and first and second members dissolve at different rates and/or dissolve away at different times.

摘要： In accordance with this invention, a DRAM with a staggered bitline sense amplifier configuration utilizes an I/O data path scheme which minimizes the time delay through the I/O data path. The DRAM includes a first and a second memory arrays wherein a first external sense amplifier receives on an input terminal a signal corresponding to the state of a memory cell selected from the first memory array via a first column decoding circuit. A second external sense amplifier receives on an input terminal a signal corresponding to the state of a memory cell selected form the second memory array via a second column decoding circuit. Each of the two external sense amplifiers has an output terminal which are shorted together. A tristate signal feeding another input terminal of each of the two external sense amplifiers is used to eliminate data contention on the shorted output terminals.

摘要： A bias voltage generator generates the same bias voltage VBB for different external power supply voltages EVCC (for example, for EVCC=3.3V or 5.0V). During power-up, the charge pump that generates VBB is controlled by an enable signal ExtEn referenced to EVCC. Later an internal supply voltage IVCC becomes fully developed to a value independent from EVCC (for example, IVCC=3.0V), and the charge pump becomes controlled by an enable signal IntEn referenced to IVCC. This enable signal IntEn will cause VBB to reach its target value, for example, -1.5V. This target value is independent of EVCC. During power-up, when the charge pump is controlled by ExtEn, the bias voltage VBB is driven to an intermediate value (for example, -0.5V or -1V). This intermediate value depends on EVCC, but is below the target value in magnitude. The intermediate value reduces the likelihood of latch-up during power-up, but the intermediate value does not go beyond the target value thus does not create a significant pn-junction current leakage in semiconductor regions to which the bias voltage is applied.
摘要翻译：偏置电压发生器为不同的外部电源电压EVCC产生相同的偏置电压VBB（例如，对于EVCC = 3.3V或5.0V）。在上电期间，产生VBB的电荷泵由参考EVCC的使能信号ExtEn控制。之后，内部电源电压IVCC完全发展为独立于EVCC（例如，IVCC = 3.0V）的值，并且电荷泵由参考IVCC的使能信号IntEn控制。该启用信号IntEn将使VBB达到其目标值，例如-1.5V。该目标值与EVCC无关。在上电期间，当电荷泵由ExtEn控制时，偏置电压VBB被驱动到中间值（例如，-0.5V或-1V）。该中间值取决于EVCC，但是在大小上低于目标值。中间值降低了在上电期间闭锁的可能性，但是中间值不超过目标值，因此在施加偏置电压的半导体区域中不会产生显着的pn结电流泄漏。

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.
