    摘要： A multi-lumen catheter including tip sections distal to a dividing point, the tip sections releasably joined by a method that produces a variable separation force between the tip sections along a length thereof. An increasing separation force may be imparted to the tip sections by providing an increasing bond strength in fusion zones from a distal portion of the tip sections toward the dividing point.

    摘要： Reconfirmation of the position of a catheter intravascularly placed with the assistance of ECG signals of the patient is disclosed, thus assisting in determination of subsequent catheter displacement within the patient vasculature. In one embodiment a method for reconfirming a position of an indwelling medical device within a body of a patient comprises first placing the medical device within the body of the patient using ECG signals of the patient. A first ECG signal profile relating to an initial position of the indwelling medical device after initial placement of the medical device is stored. A second ECG signal profile relating to the position of the indwelling medical device at a time subsequent to initial placement of the medical device is then acquired. The first ECG signal profile is compared with the second ECG signal profile to determine whether displacement of the indwelling medical device has occurred.

    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 therethrough 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 included on a molded insert that is incorporated into the access port so as to be visible after implantation via x-ray imaging technology.

    摘要： A conduit of relatively tough biocompatible material encloses a longitudinally extending fluid flow lumen and has a distal end configured as a catheter coupling hub. The conduit is encircled at the distal end of the catheter coupling hub and a portion of the conduit distal of and adjacent to the catheter coupling hub by a stabilization sleeve made of a contrastingly resilient, soft material suitable for skin contact applications. A pair of stabilization wings extends laterally on opposite sides from the stabilization sleeve at an attachment location separated from the portion of the stabilization sleeve in which the catheter coupling hub is received. As a result, a strain relief region is created. The stabilization sleeve is permanently attached to the conduit at the coupling hub only. The portion of the conduit distal of and adjacent to the catheter coupling hub extends slideably through the remainder of the length of the stabilization sleeve affording axial and bending strain relief to that portion of the conduit.

    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.
