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： An elongated access port has a needle-impenetrable housing enclosing a fluid reservoir. The housing includes a base having a floor with an upstanding encircling sidewall and a cap having a top wall with a depending encircling skirt. The skirt of the cap receives the sidewall of the base. An access aperture extends through the top wall of the cap to communicate with the fluid reservoir. The access aperture is encircled by a continuous rim having an elongated shape in the plane of the access aperture. The rim of the access aperture may be elliptical, oval, polygonal, or parabolic-ended. An elastomeric, needle-penetrable, generally planar septum is disposed in the access aperture with the periphery of the septum in sealing engagement with the rim of the access aperture. Prior to installation, the septum has a periphery with a cross section in the plane of the septum that is geometrically proportional to and larger than the shape of the access aperture. Installation causes the periphery of the septum to be displaced inwardly by the rim of the access aperture in a direction parallel to the plane of the septum. In view of the relative shapes of the rim of the access aperture and the periphery of the septum, this produces substantially uniform hydrostatic pressure in regions of the installed septum that are subjected in use of the access port to needle penetrations. Opposite faces of the periphery of the septum are urged toward each other between the cap of the housing and the top of the sidewall of the base of 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 balloon catheter having a balloon disposed upon an elongate shaft near a relatively rigid distal insertion tip, a fluid lumen for fluid communication with a body cavity and an inflation lumen for fluid communication with the balloon. The balloon holds the catheter tip within a body cavity such as the stomach for long-term enteral feeding. The balloon is configured such that upon inflation, the balloon distends distally to cover the distal tip thus insulating it from sensitive anatomy.

摘要： A subcutaneous implantable access port is formed of a housing having a pair of noncircular fluid cavities enclosed therein by a floor, walls upstanding from the floor, and a self-sealing septum positioned above each fluid cavity. The housing is constructed of a base, a septum support, and a cap. An outlet stem exits the base and communicates with the fluid cavities therein. The outlet stem has two prongs formed in a side-by-side configuration extending outwardly from the base. The prongs are formed within the stem channels in fluid communication with the fluid cavities. Protruding radially outwardly from the portion of said prong is a barb. Fluid injected into the fluid cavity through the septum flows through a smooth transition region in which the cross-sectional area is smoothly reduced from the corresponding fluid cavity. A locking sleeve provides radial inward pressure upon the catheter which is slid over the outlet stem, thereby insuring that the catheter remains mounted on the outlet stem.

摘要： An access port for providing subcutaneous access to a patient is disclosed. In one embodiment, the port includes an internal body defining a fluid cavity that is accessible via a septum. A compliant outer cover including silicone is disposed about at least a portion of the body. A flange is included with the port body and is covered by the outer cover. The flange radially extends about a perimeter of the port body proximate the septum so as to impede penetration of a needle substantially into the outer cover in instances where the needle misses the septum. The flange can further include both an anchoring feature for securing the outer cover to the port body and an identification feature observable via x-ray imaging technology for conveying information indicative of at least one attribute of the access port. The outer cover provides a suitable surface for application of an antimicrobial/antithrombotic coating.
