    摘要： An apparatus is disclosed for endoscopic application of surgical staples to body tissue in laparoscopic hernia surgery, preferably with surgical mesh. The apparatus includes a staple storage cartridge supported on a pivotal support system at the distal end of the endoscopic section. An elongated pusher system extends from the frame to the endoscopic section and individually advances the staples distally. A pair of legs project distally from the pusher plate to engage the staple during closure to prevent unwanted roll or deformation of the staple. A trigger system actuates the pusher. An anvil structure having rounded anvil legs to match the configuration of the staples provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue to attach the portion of the mesh to the body tissue. The staple storage cartridge may be pivoted with respect to the longitudinal axis of the endoscopic section from 0.degree. to about 20.degree., 45.degree., and 65.degree. and the cartridge may be rotated about its own axis independent of the endoscopic section. The distalmost tip of the instrument includes two distally extending members which engage the body tissue to stabilize the orientation of the instrument during application of staples.

    摘要： An apparatus is disclosed for endoscopic application of surgical staples adapted to attach surgical mesh to body tissue in laparoscopic hernia surgery. The apparatus includes a frame, and a generally elongated endoscopic section connected to the frame and extending distally therefrom. A staple storage cartridge is removably supported on a pivotal support system at the distal end portion of the endoscopic section with each staple being configured and adapted to attach the mesh to the body tissue. An elongated pusher system formed of several assembled components and extending from the frame to the endoscopic section is provided for individually advancing at least one staple at a time distally for positioning adjacent the surgical mesh and the body tissue. The pusher system also includes a trigger system to actuate the pusher. The trigger system is provided with perceptible tactile sensing means to indicate when the legs of the staple being advanced are exposed so as to be visible to the user for positioning and orientation purposes. Anvil means provides for individually closing each staple to encompass at least a portion of the surgical mesh and to penetrate the body tissue in a manner to attach the portion of the mesh to the body tissue. Projecting distally of the cartridge support system is a pair of legs which are dimensioned and configured to engage the staple during closure to prevent unwanted roll or deformation outside of the plane of the staple.

    摘要： A dialysis catheter including a first portion having an outer wall having a first diameter, an elongated distal portion having a second diameter smaller than the first diameter, and a transition region between the first portion and distal portion. A first longitudinally extending venous lumen is configured to deliver blood. First and second independent longitudinally extending arterial lumens are configured to withdraw blood from a patient. The venous lumen and arterial lumen have first and second regions each positioned a first distance from the outer wall of the catheter and a third region positioned a second shorter distance from the outer wall of the catheter to form an arch shaped wall portion progressively increasing in thickness from the third region toward the first region and from the third region to the second region.

    摘要： A surgical delivery instrument for delivering a vascular hole closure device having a hole covering member. The delivery instrument comprises a housing, a plunger and an advancer movable within the housing, the advancer having a first portion and a distal portion hingedly connected to the first portion and forming a casing for supporting the hole covering member. Distal movement of the advancer pivots the casing from an angled position to a more linear position to change the orientation of the covering member from a transverse position to a more aligned position. The plunger is advanceable to advance the covering member into the vessel.
