摘要： A sacrificial catheter assembly and method of use for placing a functional catheter within the body of a patient, such as into the patient's vasculature, is disclosed. In one embodiment, the sacrificial catheter assembly comprises a sacrificial catheter including an elongate body that defines a longitudinally extending lumen. A stylet is removably received within the lumen of the sacrificial catheter such that the catheter and stylet can be advanced together to a target destination within the body of the patient. The sacrificial catheter is configured so as to then be proximally slid over the stylet to remove the sacrificial catheter from the body while the stylet remains in place at the target destination. A functional catheter can then be distally slid over the stylet to place the functional catheter at the target destination. The stylet can then be removed from the body of the patient.

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： Assemblies for identifying a power injectable vascular access port are described. One assembly includes a vascular access port, a first identifiable feature, a second identifiable feature, and a third identifiable feature. The first identifiable feature is incorporated into the access port and identifies the access port as suitable for flowing fluid at a fluid flow rate of at least 1 milliliter per second through the access port. The second identifiable feature is incorporated into the access port and identifies the access port as suitable for accommodating a pressure within the cavity of at least 35 psi. The third identifiable feature is separated from the access port and confirms that the implanted access port is both suitable for flowing fluid at a rate of at least 1 milliliter per second through the access port and for accommodating a pressure within the cavity of at least 35 psi.

摘要： A catheter connector system for a subcutaneously placed catheter and method of attaching a catheter to extracorporeal medical equipment. The catheter connector system and method enables proximal trimming of the placed catheter and facilitates precise positioning of both distal and proximal ends of a catheter. The method includes sliding a boot and dilator combination over a portion of a catheter extending from a venipuncture site until a distal end of the boot is positioned in the venipuncture site, removing the dilator from the boot, and trimming a portion of the catheter extending from a proximal end of the boot. A bifurcation assembly may be attached to the proximal end of the boot following trimming of the catheter.

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.

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： A dual reservoir access port includes a metal casing having a top surface with recessed, open proximal and distal fluid reservoirs. Projecting from the casing on the side of the distal fluid reservoir opposite from the proximal fluid reservoir is a dual prong metal outlet stem. The distal fluid reservoir is carried within an open-topped basket that is disposed in a cup formed in the top surface of the casing. A first fluid flow pathway extends from the proximal fluid reservoir, between the basket and the wall of the distal cup, to the outlet stem. A second fluid flow pathway extends directly from the distal fluid reservoir to the outlet stem. A needle-penetrable compound septum is disposed against the casing simultaneously closing the top of the proximal fluid reservoir and the top of the distal fluid reservoir. A plastic jacket clamps the septum against the casing and compresses the periphery of the septum to effect a fluid seal by the septum of each of the fluid reservoirs. An annular sleeve mechanically locks and fluid couples a dual lumen catheter to the outlet stem. The catheter may be chosen from among three dual lumen catheters, each having a combination of material composition and lumen configuration that is distinct from those of the others of the catheters.
