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： A guidance system for assisting with the insertion of a needle or other medical component into the body of a patient is disclosed. The guidance system utilizes ultrasound imaging or other suitable imaging technology. In one embodiment, the guidance system comprises an imaging device including a probe for producing an image of an internal body portion target, such as a vessel. One or more sensors are included with the probe. The sensors sense a detectable characteristic related to the needle, such as a magnetic field of a magnet included with the needle. The system includes a processor that uses data relating to the detectable characteristic sensed by the sensors to determine a position and/or orientation of the needle in three spatial dimensions. The system includes a display for depicting the position and/or orientation of the needle together with the image of the target.

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 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： 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.
