Abstract: A hemofiltration system is provided in which ultrafiltrate is purified by reverse osmosis for reinfusion. Non-sterile infusate concentrate is dialyzed into the purified ultrafiltrate and combined with cleared blood which is returned to the patient. In another system, a hemofilter is used to sterilize essentially pure, non-sterile water for dilution of sterile infusate concentrate, then the hemofilter is used to filter blood, the infusate concentrate being combined with cleared blood for return to the patient.

Abstract: A laundry treatment composition comprising a water-soluble or water-dispersible rebuild agent for deposition onto a fabric during a treatment process wherein the material undergoes during the treatment process, a chemical change by which change the affinity of the material for the fabric is increased.

Abstract: Methods, systems, and kits for extracorporeally circulating and processing blood are described. The systems include a pump, a processing unit, and blood drawn return lines for accessing a patient's vasculature. Blood flow through the return line is measured and pump speed controlled to maintain a desired blood flow rate. Alarm conditions can be initiated when expected pump performance differs from that needed to maintain the control point flow rate. By using a ultrasonic flow detector, gas bubbles in the blood flow can be detected.

Abstract: Methods, apparatus, and kits are provided for performing peritoneal dialysis. In a first aspect, subcutaneous and transcutaneous systems are described for performing continuously cycling peritoneal dialysis. In a second aspect, fully implanted systems are described for performing flow-through peritoneal dialysis.

Abstract: Systems for draining retained body fluids comprise an implantable port in an access tube. Usually, a drainage cannula for connecting the implantable port to a site of fluid retention is also provided. The implantable port and drainage cannula are implanted subcutaneously with one end of the cannula within the site of fluid retention and the port located remotely from such site. Drainage may then be effected by percutaneously introducing the access tube to the port and optionally applying a vacuum. Kits comprise the implantable port together with instructions for implanting the port as described above. Kits also comprise an access tube with instructions for use for accessing an implanted port as described above.

Abstract: Methods and apparatus for percutaneously accessing an implanted port use an access cannula which is periodically introduced to an aperture on the implanted port so that the cannula passes through the same tissue tract. It has been found that repeated passage of the cannula through the same tissue tract reduces patient trauma, with minimized bleeding, reduction in sensitivity. The tract may be initially formed by percutaneously placing a penetrating element through intact skin to the port and leaving the element in place for a time sufficient to created the tract.

Abstract: An access port comprises a base and a flexible conduit. The port is subcutaneously implanted and the conduit is attached directly or indirectly to a blood vessel or other body lumen or cavity. An actuator mechanism is provided with a linkage which opens a valve in the port in response to percutaneous insertion of a needle into the access port. In particular, insertion of the needle opens the clamping mechanism to permit flow through the conduit between the blood vessel and the needle.

Abstract: An access catheter for percutaneously connecting to a subcutaneously implanted port comprises a catheter body having a distal end and a proximal end. A needle or other access tube is connected to the distal end of the catheter body through a fitting, optionally at a right angle relative to the catheter body. A compressible element impregnated with an antiseptic, antibiotic, anesthetic, or other active agent, is provided adjacent the distal end of the catheter body and surrounding the needle. When the needle is percutaneously introduced to the port, the compressible element will be compressed to express the agent onto the skin surface surrounding the penetration site.

Abstract: Methods and apparatus for percutaneously accessing an implanted port use a large bore coring needle. The coring needle is periodically introduced to an aperture on the implanted port so that the needle passes through the same tissue tract. It has been found that repeated passage of the needle through the same tissue tract reduces patient trauma, with minimized bleeding, reduction in sensitivity, in contrast to the use of non-coring needles.

Abstract: A catheter with valve for implantation in a vascular structure of a living being. The catheter is in the general shape of a "T" with the top of the "T" implanted within the lumen of a vascular structure, and the leg of the "T" extending out of the vascular structure through an incision in the vascular structure. The lumen of the implanted portion of the catheter completely occupies the lumen of the vascular structure, causing all blood flow through the vascular structure to be directed through the implanted portion of the catheter. A valve is placed in the wall of the implanted portion of the catheter which opens into the lumen of the leg of the "T" of the catheter upon application of sufficient differential pressure between the lumens of the two portions of the catheter.

Abstract: An implantable device grafted directly to vascular structures for high volume blood and/or fluid infusion and/or removal for such purpose as hemodialysis, apheresis, exchange transfusion, or large volume fluid infusion. The device is also adaptable to intermittent access to the venous or arterial circulations for purpose of blood sampling or giving medications. The device is comprised of an implantable fluid chamber connected to a vascular shunt which is then grafted directly to the vascular structure (e.g. artery or vein). The vascular end of the device employs a valve to prevent reflux of blood and subsequent washout of anticoagulant during periods when the device is not in use. The device is accessed percutaneously with a needle or needle-introduced catheter and is filled with anti coagulant prior to needle withdrawal to prevent thrombosis.

The device is also adaptable to intermittent access to the venous or arterial circulations for purpose of blood sampling or giving medications. The device is comprised of an implantable fluid chamber connected to a cannula or shunt segment which is then grafted directly to the vascular structure (e.g. artery or vein) using a sewable cuff located at the vascular end of the cannula or shunt segment. The vascular end of the device employs a valve which is directly adjacent to the vascular structure after grafting, in order to prevent reflux of blood and subsequent washout of anticoagulant during periods when the device is not in use. The device is accessed percutaneously with a needle or needle-introduced catheter and is filled with anti-coagulant prior to needle withdrawal to prevent thrombosis.

Abstract: A control system for lighting a bank of fluorescent lamps, includes input terminals (10, 11) for a mains voltage (e.g. 240 v) and output terminals (20, 21) to which the bank of lamps is connected. A transformer (T1) provides a reduced voltage (216 v) as compared to the mains supply voltage. The transformer (T2) provides a supplementary voltage (24 v). Upon start up of the circuit, a control circuit (CC) operates contact (A1) to energize the transformer (T2) so that terminals (20, 21) receive both the reduced voltage from (T1) and the supplementary voltage from (T2) (i.e. 240 v) which is sufficient to ignite the fluorescent lamps. The control circuit (CC), after a predetermined delay (e.g., 15 seconds), switches contact (A1) to disconnect the supplementary voltage from (T2). The lamps then continue to operate on the reduced voltage (216 v) thereby reducing the power consumed by the lamps.
