Patent number: 7135008Abstract: 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.Type: GrantFiled: December 2, 2003Date of Patent: November 14, 2006Assignee: CHF Solutions, Inc.Inventors: John J. O'Mahony, Steven Bernard, Sean P. Skubitz

Patent number: 6592232Abstract: 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.Type: GrantFiled: November 16, 2001Date of Patent: July 15, 2003Assignee: Intel CorporationInventor: Steven Bernard McGowan

Patent number: 6533747Abstract: 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.Type: GrantFiled: October 30, 2000Date of Patent: March 18, 2003Assignee: CHF Solutions, Inc.Inventors: Hans-Dietrich Polaschegg, Steven Bernard, Howard R.

Patent number: 5772076Abstract: 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.Type: GrantFiled: July 26, 1996Date of Patent: June 30, 1998Assignee: White Cap, Inc.Inventors: Steven Bernard Juk, Leo R.

Patent number: 4063665Abstract: 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.Type: GrantFiled: December 6, 1976Date of Patent: December 20, 1977Assignee: Chemtrust Industries CorporationInventors: Barry Schneider, Steven Bernard
