摘要： A low-profile access port for subcutaneous implantation within the body of a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable a catheter-bearing needle to access the port without difficulty. In addition, the access port includes a valve/seal assembly to permit pressurized fluid injection through the port while preventing backflow. In one embodiment, therefore, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end thereof, and a receiving cup. The receiving cup is concavely shaped to direct a catheter-bearing needle into the conduit via the inlet port. The receiving cup is oriented substantially toward a skin surface when subcutaneously implanted within the patient to ease needle impingement thereon. A valve/seal assembly disposed in the conduit enables passage of the catheter therethrough while preventing fluid backflow.

摘要： A catheter connection system (32, 340, 394, 634) is defined by a rigid, tubular stem (34, 278, 288, 318, 342, 396, 496, 530, 574, 612) attached at a proximal end thereof to a medical device (016, 222, 246, 274, 312, 366, 636). The stem has one or more engagement barbs (49, 226, 254, 280, 290, 320, 358, 408, 466, 538, 586) encircling and radially, outwardly extending on an exterior surface of the stem. The engagement barbs can be configured having a variety of different sizes and positions. A locking barb (50, 228, 258, 294, 322, 360, 412, 472, 510, 541, 632) also encircles and radially, outwardly extends on the exterior surface of the stem. The locking barb is positioned between the medical device and the engagement barbs. A variety of fastening assemblies (57, 300, 304, 328, 414, 480, 492, 555, 600) are provided for inwardly compressing a portion of a body wall (53, 83, 376) of a selected catheter (54, 58, 244, 302, 330, 386, 416, 474, 518, 544, 594), chosen from two or more catheters, against the engagement barbs or locking barb on the stem when the stem is received in the lumen (54, 58, 244, 302, 330, 386, 416, 474, 518, 544, 594) of the selected catheter. The fastening assemblies create a mechanical joinder and liquid-tight seal between the selected catheter and the stem.

摘要： A vascular access port (202) has a housing (210) that includes a base (226) and a cap (228) that capture compound septum (310) to seal each of a pair of distinct fluid reservoirs (250, 252) in the base (226). Distinct target domes (212, 214) of the compound septum (310) are interconnected and encircled by a planar septum web (312) and exposed through respective access apertures (234, 236) in the cap (228). An isolation groove (324) and sealing ridges (326, 328) traverse the lower surface (316) of the septum web (312) between the target domes (212, 214). The outlet stem (222, 370, 390) of the access port (202) is integrally formed with the base (226) of the housing (210). An open fluid channel (262, 264) communicates from each fluid reservoir (250, 252) to a corresponding enclosed fluid passageway (272, 276) in the outlet stem (222, 370, 390) and is closed by a portion (352) of the compound septum (310).

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.

摘要： A procedure kit that removably retains components to be used during a medical procedure, such as the insertion of a catheter into a patient, is disclosed. The procedure kit is securable to a surface or structure such that the kit is positioned as desired by the clinician, thus minimizing chances that the kit will fall to the ground or undesirably move. In one embodiment, the procedure kit comprises a body defining a plurality of pockets that are sized to removably receive therein components for use in the medical procedure, an openable flap that covers at least a portion of the pockets; and an adhesive portion included on a portion of the body to enable the procedure kit to be secured to a structure or surface proximate to the patient, such as the sterile drape covering the patient.

摘要： A septum for use in sealably covering a fluid cavity of an implantable medical device, such as an access port, is disclosed. The septum is resilient and includes a reinforcement structure that bolsters septum placement over the fluid cavity so as to inhibit unintended separation of the septum from the medical device when the fluid cavity is under pressure, such as during power injection of fluid into the fluid cavity. In one embodiment the septum comprises a resilient septum body that includes a flange disposed about a perimeter thereof. A reinforcement component is disposed in the flange for reinforcing engagement of the flange with a corresponding groove defined about an opening to the fluid cavity of the medical device so as to inhibit unintended detachment of the septum from the medical device. The reinforcement component in one embodiment includes an annular cord disposed in the flange.

摘要： A dual reservoir access port (18) includes a metal casing (28) having open proximal and distal fluid reservoirs (30, 34). A dual prong metal outlet stem (36) projects from the casing (28) on the side of the distal fluid reservoir (34) opposite from the proximal fluid reservoir (30). The distal fluid reservoir (34) is carried within an open basket (32) that is disposed in a receiving cup (31) in the top (118) of the casing (28). A first fluid flow pathway (162) extends from the proximal fluid reservoir (30) to the outlet stem (36) between the basket (32) and the wall (36) of the receiving cup (31). A second fluid flow pathway (80) extends directly from the distal fluid reservoir (34) to the outlet stem (36). A needle-penetrable compound septum (38) disposed against the casing (28) over the open fluid reservoirs (30, 34) is clamped against the casing (28) by a plastic jacket, compressing the periphery of the septum (38) and sealing each of the fluid reservoirs (30, 34).

摘要： An elongated access port (18) has a needle-impenetrable housing (40) that includes a base (44) with an upstanding encircling sidewall (70) and a cap (42) with a depending encircling skirt (46) for receiving the sidewall (70). An access aperture (130) encircled by a continuous rim (138) of elongated shape extending through the cap (42) may be elliptical, oval, polygonal, or parabolic-ended. A needle-penetrable septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) is installed in the access aperture (130) with the periphery (138, 188, 204) of the septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) in sealing engagement with the rim (128) of the access aperture (130). Prior to installation, periphery (138, 188, 204) is geometrically proportional to and larger than the access aperture (130). The relative sizes and shapes of the rim (128) and the periphery (138, 188, 204) produce substantially uniform hydrostatic pressure in regions of the installed septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) subjectable to needle penetration. Opposite faces (140, 142) of the septum (91, 168, 170, 172, 178, 180, 182, 187, 202, 232) at the periphery (138, 188, 204) are urged together between the cap (42) and the top (120) of the sidewall (70) of the base (44).

摘要： A stabilized catheter tube for insertion into a body of a patient. The catheter tube includes a distal portion that remains stable during fluid infusion into the patient, thus reducing or eliminating whipping of the catheter distal tip. In one embodiment, the catheter tube defines at least one lumen and is formed from a tube material that defines a proximal portion and a distal portion of the catheter tube. The catheter tube is configured such that the arithmetic product of an elastic modulus and an area moment of inertia for the distal portion of the catheter tube is greater relative the arithmetic product of an elastic modulus and an area moment of inertia for the proximal portion of the tube. In one embodiment, the catheter tube is operably attached to an implantable access port and includes an enlarged distal portion relative a proximal portion of the catheter tube.
