Abstract: A filter for an extracorporeal blood circuit including a bundle of hollow fibers having an end section encased in a potting material, wherein the end section of potting material has an end surface with open ends of the fibers distributed throughout the end surface, and a filter header cap having an inlet connectable to a blood line and an open end sealed around a side surface of the end section of the bundle of hollow fibers.

Abstract: An extracorporeal blood circuit including: a withdrawal conduit connectable to a coronary withdrawal catheter; a withdrawal pump connectable to the withdrawal conduit, wherein a pumping rate of the withdrawal pump determines a blood withdrawal rate from the coronary withdrawal catheter; a filter having an input connected to the withdrawal conduit and a blood output connected to an infusion conduit and a filtrate output connected to a filtrate conduit; a filtrate measurement device to determine an amount of filtrate removed from the blood in the filter; a fluid supplementation conduit providing a blood replacement fluid to at least one of the withdrawal conduit, filter and infusion conduit; a supplementation pump connectable to the fluid supplementation conduit, wherein a pumping rate of the supplementation pump determines a rate at which the blood replacement fluid flows into the blood flowing through the blood circuit, and a controller regulating the pumping rate of the supplementation pump such that the rat

Abstract: Method and apparatus for the extracorporeal treatment of blood by utilizing a peripherally inserted dual lumen catheter assembly for the continuous removal and return of blood for renal replacement treatment, in particularly, treatment of congestive heart failure and fluid overload by ultrafiltration. A catheter is inserted in a peripheral vein and maneuvered upward through the vascular system to access the reservoir of blood in the large or great veins for continuous blood withdrawal and treatment. Air-tight connectors are incorporated in the catheter assembly to overcome the untoward effects of negative pressure in blood withdrawal.

Abstract: An integrated disposable cartridge for dialysis or ultrafiltration treatment of blood includes integral pressure sensors. Sensors are embedded in the blood filter on the cartridge to measure the pressure of blood or other fluids in the filter.

Abstract: A peripherally inserted catheter assembly having multiple side holes to be inserted in a peripheral vein and maneuvered upward through the vascular system to access the reservoir of blood beyond and between the venous flappers for continuous blood withdrawal and treatment.

Abstract: A tapered extracorporeal blood tube having at least a first end of the tube with a large diameter, a narrow diameter section of the tube, and a tapered tube transition section between the first end and the narrow section. The tapered blood tube reduces the overall blood flow volume in the circuit.

Abstract: An integrated disposable cartridge for dialysis or ultrafiltration treatment of blood is disclosed that includes integral miniature pressure sensors. Sensors are embedded in the tubing of the cartridge to measure pressure of blood or other fluids. Cartridge elements form a continuous smooth bore passage for blood that reduces probability of clotting.

Abstract: An optical system using ambient light. The system includes a screen to be illuminated, an internal light source and an external light collector to collect ambient light to illuminate the screen. A switch may be used to activate the internal light source, providing internal light to be combined with the ambient light to illuminate the screen. A light sensor may also be used to detect the level of light presented to the screen, with or without a controller to automatically control the process of providing illumination to the screen.

Abstract: An extracorporeal blood circuit is disclosed for withdrawing, filtering and returning blood from peripheral blood vessels. The blood passage in the circuit extends through a withdrawal tube connected to a catheter in a peripheral vein, a filter, one or more pressure sensors and return tube also connected to a catheter in a peripheral vein (which may or may not be the same vein as used for the withdrawal tube). The blood passage is air free, and has smooth passage walls which promoted continuous and uniform flow of the blood through the circuit.

Abstract: A dispensing closure which is particularly suited for hot fill packaging wherein vacuum conditions are present as well as the packaging of carbonated beverages wherein superatmospheric conditions are present. The dispensing closure includes a rotatable outercap that overlies, and is relatively moveable with respect to, an inner cap secured to a container mouth. The inner and/or outer cap can be integrally formed with a resilient thermoplastic gasket liner system that provides vacuum seals both between the inner or outer caps and container as well as between the inner and outer caps. The closure can be equipped with a tamper indicating band, preferably located at the base of the outer cap, which will separate from the outer cap when it is rotated and axially moved upwardly from the closed to the dispensing position.

Abstract: A container holding a supply of a volatile liquid material to be poured therefrom includes an upper pouring spout-forming section over which, in the preferred form of the invention, is placed a removable attachment unit which appears to be a vertical cap-forming continuation of the top of the container. The attachment unit preferably has a compartment opening to the outside thereof and containing a liquid-absorbing material into which a portion of the liquid volatile material of the container is ultimately poured when the attachment is removed from the container. In a less preferred form of the invention, the dispensing unit-forming attachment is removably attached to and preferably forms a vertical continuation of the bottom of the container.
