摘要： A blood treatment catheter pre-assembled with a stiffening tube is provided. The catheter includes a withdrawal lumen and a supply lumen each having distal split tube unjoined segments and an intermediate joined segment. The split tube segment of the supply lumen is provided with a sidewall aperture. The stiffening tube extends through the withdrawal split tip tube, out the distal end of the withdrawal tube, through the aperture of the supply split tip tube and through the split tip supply tube distal of the aperture, out the distal end of the split tip supply tube. When the stiffening tube is positioned inside the catheter, the aperture is adjacent to the withdrawal tube distal opening so as to minimize stiffening tube exposure and to provide a smooth exterior profile. In a preferred design, the tubes and their lumens, over their common length, are semi-circular to provide a circular profile for the catheter.

摘要： A method of making a multi-lumen catheter includes forming a catheter body including a first lumen and a second lumen, and forming a catheter tip having a first channel terminating distally in a first opening on a first side of the catheter tip, and a second channel terminating distally in a second opening on a second side of the catheter tip opposite of the first side. The first and second openings of the catheter tip extend through an outer wall of the catheter tip to a dividing section. The catheter tip is affixed to the catheter body such that the first channel is aligned with the first lumen and the second channel is aligned with the second lumen.

摘要： A multi-lumen catheter assembly for use in the extracorporeal treatment of a body fluid of a patient. The catheter assembly includes an elongated catheter body having a pair of lumens extending therethrough, and a septum separating the lumens. The catheter body has an aspiration port in communication with a first lumen for transporting fluid withdrawn from a body vessel to a treatment unit, and an infusion port in communication with a second lumen for return of treated fluid to the vessel. The infusion port is positioned distal of the aspiration port along a length of the catheter body. A flexible member is provided, wherein the flexible member has an end receivable in the first lumen and another end engaged with the catheter body distal of the aspiration port. The flexible member is structured and arranged to maintain a spacing between the aspiration port and a wall of the vessel.

摘要： Method for in-vivo plasmapheresis utilizing a plurality of elongated hollow microporous filter fibers periodically interrupt diffusion of blood plasma from a patient, and, for a selected time, directing backflush fluid into the fibers at a pressure and interval sufficient to cleanse the fiber pores, after which plasma diffusion is resumed. The backflush fluid, preferably a normal saline solution, may contain an anticoagulant such as heparin, citrate or NO donor in suitable concentration for systemic anti-coagulation or for treating the fiber for thromboresistance.

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 treatment assembly is positioned along an AV-fistula and couples therapeutic energy to an adjacent area due to a material response to an applied energy field from a remotely located energy source. The treatment assembly may be delivered into the fistula through a hemodialysis needle, or may be secured to the fistula graft itself and implanted therewith within a patient. A cover provides a shield between an anastomosis area and blood flow. Another AV-fistula includes a valved reservoir that receives a fluid agent from a hemodialysis needle while moving the needle into or from the fistula; the agent leaks from the reservoir into the fistula lumen. Another valved fistula is adjustable between an open condition and closed conditions during and between hemodialysis treatments, respectively. Another AV-fistula has a bladder reservoir coupled to a second refillable fluid reservoir and is adapted to locally deliver a therapeutic agent into the fistula lumen.
