摘要： An access port for subcutaneous implantation is disclosed. The access port may include a body for capturing a septum for repeatedly inserting a needle therethrough into a cavity defined within the body. The access port may further include at least one feature structured and configured for identification of the access port subsequent to subcutaneous implantation. Methods of identifying a subcutaneously implanted access port are also disclosed. For example, a subcutaneously implanted access port may be provided and at least one feature of the subcutaneously implanted access port may be perceived. The subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is included on a molded insert that is sandwiched between base and cap portions of the access port so as to be visible after implantation via x-ray imaging technology.

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 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： Normal saline and other infusate solutions for infusion into the body of a patient during medical treatment are disclosed. In particular, infusates are disclosed that are formulated to resist changes to the pH of the solution when subjected to sterilization procedures that employ ethylene oxide gas. In one embodiment, a buffered infusate suitable for disposal in a syringe or other container is disclosed. The syringe is sterilizable using ethylene oxide. The buffered infusate comprises an aqueous solution that is disposed in the syringe and is suitable for infusion into a body of a patient. A buffer component is added to the aqueous solution to form a buffered solution. The buffer component is configured to resist a change in the pH of the buffered solution upon exposure of the buffered solution to the ethylene oxide during sterilization of the syringe.

摘要： A multi-lumen catheter defined by at least two separate tip sections (40, 50) distal to a dividing point (30) 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 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.
