    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 access port for subcutaneous implantation is disclosed. Such an access port may comprise a body for capturing a septum for repeatedly inserting a needle into a cavity defined within the body. Further, the access port may 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. Further, the subcutaneously implanted access port may be identified in response to perceiving the at least one feature. In one embodiment, an identification feature is engraved or otherwise defined by the access port, so as to be visible after implantation via x-ray imaging technology.

    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.
