摘要： A multi-lumen catheter defined by at least two separate tip sections distal to a dividing point includes strategic placement of openings in the tip sections to facilitate fluid flow and minimize typical problems associated with catheters. In a multi-lumen catheter having tip sections with a releasably joined or splittable region, the bond strength between the tip sections is varied along their length such that an increasing separation force is required to separate the tip sections from one another distal to the dividing point. Delivery of a multi-lumen catheter is improved with respect to both sheathed and non-sheathed delivery methods, in which a friction reducing structure is provided on either the catheter, delivery sheath or both to provide a buffer for a sheathed delivery and in which a unique guidewire aperture or additional lumen is provided in at least one of the tip sections for a non-sheathed delivery.

摘要： A vascular access port enclosing a pair of distinct fluid reservoirs includes a two-piece housing that captures an integrally-formed compound septum to seal both of the fluid reservoirs for selective access with a hypodermic needle. The housing includes a base that defines the fluid reservoirs and a cap in which the base is received with the compound septum therebetween. The compound septum includes two distinct target domes that are exposed to the exterior of the housing through respective access apertures in the cap, when the compound septum is captured in the housing. A planar septum web interconnects and encircles the target domes. The side of the septum web opposite from the target domes is formed into a recessed isolation groove that traverses the septum web between the target domes. Sealing ridges depend from this side of the septum web on either side of the isolation groove. The outlet stem of the access port is integrally formed with the base of the housing. In the base an open-topped fluid channel communicates from each fluid reservoir to a corresponding enclosed fluid passageway in the outlet stem. The open top of each fluid channel is closed by a portion of the compound septum captured in the housing.

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： 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.
