摘要： A catheter connector system for a subcutaneously placed catheter and method of attaching a catheter to extracorporeal medical equipment. The catheter connector system and method enables proximal trimming of the placed catheter and facilitates precise positioning of both distal and proximal ends of a catheter. The method includes sliding a boot and dilator combination over a portion of a catheter extending from a venipuncture site until a distal end of the boot is positioned in the venipuncture site, removing the dilator from the boot, and trimming a portion of the catheter extending from a proximal end of the boot. A bifurcation assembly may be attached to the proximal end of the boot following trimming of the catheter.

摘要： A dual reservoir access port includes a metal casing having a top surface with recessed, open proximal and distal fluid reservoirs. Projecting from the casing on the side of the distal fluid reservoir opposite from the proximal fluid reservoir is a dual prong metal outlet stem. The distal fluid reservoir is carried within an open-topped basket that is disposed in a cup formed in the top surface of the casing. A first fluid flow pathway extends from the proximal fluid reservoir, between the basket and the wall of the distal cup, to the outlet stem. A second fluid flow pathway extends directly from the distal fluid reservoir to the outlet stem. A needle-penetrable compound septum is disposed against the casing simultaneously closing the top of the proximal fluid reservoir and the top of the distal fluid reservoir. A plastic jacket clamps the septum against the casing and compresses the periphery of the septum to effect a fluid seal by the septum of each of the fluid reservoirs. An annular sleeve mechanically locks and fluid couples a dual lumen catheter to the outlet stem. The catheter may be chosen from among three dual lumen catheters, each having a combination of material composition and lumen configuration that is distinct from those of the others of the catheters.

摘要： Vascular access catheters that include a catheter body having one or a plurality of lumens longitudinally extending therethrough. The lumens have cross-sectional shapes that enhance kink resistance, support reliable slit valve operation, and couple securely with the outlet stem of a multiple reservoir implantable access port. In a dual lumen catheter disclosed, each of the lumens are defined by a plurality of longitudinally extending generally linear inner wall surfaces. The inner wall surfaces when viewed in a transverse cross section of the catheter body taken normal to the longitudinal access have trapezoidal shapes. Other cross-sectional shapes are also illustrated. A generally planar septum separates the pair of lumens. The lumens effect a fluid-tight mechanical engagement between the D-shaped outlet prongs of a conventional outlet stem of an implantable dual reservoir access port, highly reliable two-way, three-position slit valves may be associated with each of the lumens. The valve for each lumen has a closed position thereof in which fluid communication is precluded between the lumen and the exterior of the catheter body, but the valve is selectively operable under the influence of appropriate pressure differentials between the lumens and the exterior of the catheter from the closed position into either an inwardly or an outwardly open position.

摘要： An ion conducting device having a plurality of solid electrolyte plates arranged into a stack, each electrolyte plate having electrode material adherent to a significant portion thereof. A plurality of individual spacers are disposed between adjacent electrolyte plates in the stack, each spacer spacing successive electrolyte plates apart, and defining a plurality of chambers in the spaces between adjacent electrolyte plates. The electrode material on the electrolyte plates is electrically connected whereby electrode material on every other successive plate is connected in series, from one end of the stack to the other, whereupon the electrical path wraps around the stack and extends back along the stack and connects in series the electrodes not previously connected.

摘要： A safety needle assembly of an infusion set for infusing fluids into a subcutaneously implanted access port is disclosed. The needle assembly is configured to prevent fluid/vapor escape therefrom so as to reduce or prevent fluid exposure to a clinician using the needle assembly. In one embodiment, the needle assembly comprises a handle portion including a needle extending therefrom, the needle defining a lumen for passage of a fluid therethrough. The needle assembly also includes a safety assembly defining a needle hole through which the needle initially extends. The safety assembly is selectively and axially slidable along the needle in order to shield a distal tip of the needle and prevent user contact therewith. A fluid isolation component is included in the safety assembly for isolating fluid escape from the needle to prevent exposure to a clinician.

摘要： A medical device is disclosed comprising a diaphragm having at least one slit valve disposed therein, and a valve housing configured to secure the diaphragm at a peripheral portion of the diaphragm, wherein a central portion of the diaphragm is positioned relative to the peripheral portion of the diaphragm such that compressive forces acting on the peripheral portion of the diaphragm create moment forces which bias the slit valve in a closed position. A method is disclosed for using the device in connection with a catheter for regulation of fluids to and from a patient.
