Appl. No.:

09/389934

Inventors:

Tom Westberg - Gurnee IL
James D Jacobson - Lindenhurst IL

Assignee:

Baxter International Inc. - Deerfield IL

International Classification:

A61M 136

US Classification:

422 44, 604 401, 604 61, 604 611, 604 601, 210767, 210782, 210739, 210787, 210790, 210258, 494 37, 494 43, 128DIG 12

Abstract:

Systems and methods for processing blood use at least one fluid activated pump and at least one fluid activated valve. The systems and methods apply positive and negative fluid pressures to operate the pump and valve. Different pressure conditions are applied to the pump and the valve, to insure that a valve used in conjunction with a pump is not overcome by the pressure applied to operate the pump, and that both the valve and pump are not overcome by normal system processing pressures.

James D. Jacobson - Lindenhurst IL, US

Assignee:

Baxter International, Inc. - Deerfield IL

International Classification:

B01D 67/00

US Classification:

264400, 264 138, 264 16, 264 17, 264488

Abstract:

A method of manufacturing a three dimensional structure. In one embodiment, such structures comprise porous structures suitable for implantation in a host. Such a structure preferably exhibits geometric properties that tend to promote vascularization in the area of the structure when implanted into a host. The method includes selectively applying and exposing layers of biocompatible photoimageable material to create layers forming a cross-linked latticework structure having the desired geometric properties. Each layer is formed on top of a prior layer, preferably before any layer is developed. In one form, the structure is manufactured in connection with an implant device and promotes vascularization that supports bioacceptance/biocompatibility of the implant device.

US Classification:

604 611, 604 601, 604 61, 604 401, 210782

Abstract:

Systems and related methods pump fluid through a pump. The pump comprises a pump chamber, which is responsive to applied pressures to convey fluid. The systems and methods place an electrode in electrical conductive contact with fluid in the pump chamber which, in use, is coupled to an electrical source. The electrode generates an electrical field in the pump chamber that varies according volume of fluid in the pump chamber. The systems and methods register variations in the electrical field as fluid is conveyed through the pump chamber.

International Classification:

A61M 31/00

US Classification:

604 65

Abstract:

A disposable assembly for use with a sensor assembly comprises a body, a flow restricting element, and a fluid pressure membrane. The body has a lid portion and a base portion. The body defines a fluid flow passage that forms an inlet and an outlet. The flow restricting element is positioned in the fluid flow passage between the inlet and the outlet. The membrane is located between the lid and base portions along the fluid flow passage. A reinforcing structure, such as a ring or a rigid disk, is positioned between the fluid pressure membrane and the lid portion to provide increased resistance to pressure in the fluid flow passage. The ring or disk can be a separate component or formed on the membrane. The membrane thickness adjacent to sensor access openings in the lid portion can be increased for pressure resistance, too.

International Classification:

A61K 9/22

US Classification:

6048901, 604 67

Abstract:

A fluid delivery system having a closed-loop control process for delivering a medical fluid to a patient. A fluid infusion system includes a pump for delivering a fluid to a patient via an administration tube. A flow sensor associated with the administration tube provides an indication of the actual flow rate of fluid in the administration tube. Such a flow sensor may comprise a positive displacement flow sensor constructed using micro-fabrication and/or micro-molding techniques. A reader reads the actual flow rate signal and provides an indication to a controller for controlling the pump. The flow rate information can also be used for providing status information, such as the existence of a blockage in the fluid delivery system.
