Patent number: 8663160Abstract: A priming indicator for a fluid infusion system includes a luer cap or other component of the infusion system having an indicator surface covered by a membrane. The membrane exhibits a first visual characteristic, such as being opaque, when dry and exhibits a second characteristic, such as becoming less opaque, when wet. Once the membrane becomes wet, indicia on the surface, which may be provided on a rod at least partially covered by the membrane, becomes visible, thereby indicating an intravenous tube to which the luer cap is secured has been primed or is nearly primed. The indicator may alternately be employed at an upstream end of an infusion set, such as at the port of a medical bag providing a supply of fluid, to indicate a low level of fluid in the medical bag.Type: GrantFiled: January 15, 2013Date of Patent: March 4, 2014Assignees: Baxter International Inc., Baxter Healthcare S.A.Inventors: Shmuel Sternberg, Siddharth B.

Patent number: 6060640Abstract: A permeable structure forms a chamber to hold living cells. The structure includes a first permeable region surrounding at least a portion of the chamber having a conformation that, when implanted in host tissue, substantially blocks penetration of host cells into the chamber while permitting solute transport. The structure also includes a second permeable region overlying the first permeable region having a conformation that, when implanted in host tissue, forms a permeable interface with host tissue that permits solute transport. A third permeable region is located between the first and second permeable regions. The third region comprises a solution of polymer material formed in place between the first and second permeable regions. The third permeable region bonds the first and second permeable regions together. The third permeable region also has a conformation that, when implanted in host tissue, permits solute transport between the first and second permeable regions.Type: GrantFiled: May 19, 1995Date of Patent: May 9, 2000Assignee: Baxter International Inc.Inventors: Robin G.

Patent number: 5653756Abstract: Improved Implant assemblies and methodologies provide immuno-protection for implanted allografts, xenografts, and isografts. The assemblies and methodologies establish an improved chamber for holding the implanted cells. The chambers include first and second wall elements and an intermediate sealing element. The first and second wall elements overlie an open area in the sealing member to form a chamber for holding cells for implantation. A sealed region is created between the wall elements and the sealing element body to close the chamber. In one arrangement, the sealed region is created by means of a sonic weld made while the implanted cells are present in the chamber. In another arrangement, the sealed region is created by means of applying an external force to compress the peripheral edges of the wall elements and the sealing element together while the implanted cells are present in the chamber.Type: GrantFiled: September 2, 1994Date of Patent: August 5, 1997Assignee: Baxter International Inc.Inventors: Robert A. Clarke, Robin G. Pauley, Ronald S. Hill, James H. Brauker, Shmuel Sternberg, Daniel R. Boggs

Patent number: 5527467Abstract: The invention provides dual-skinned membranes useful as one way or rectifying membranes which reduce back filtration of solute molecules in dialysis and which improve nutrient supply and product recovery in membrane bioreactors. The membranes are dual-skinned polymeric materials preferably in the form of hollow fibers. The membranes have skins of polymer on the opposite sides with differing permeability to solutes and sieving coefficient characteristics. The skin on each side have pores that are invisible at 10,000 times magnification, the microporous structure between said skins contains pores capable of retaining solutes in a molecular weight range of about 5000 to 200000 in an increased concentration between the interior and the exterior skins. Improved dialysis devices are formed by using bundles of the hollow fiber membranes as a dialysis means having rectifying properties.Type: GrantFiled: June 13, 1994Date of Patent: June 18, 1996Assignee: Baxter International Inc.Inventors: Norma J. Ofsthun, Lee W. Henderson, Richard I. Brown, Robin G. Pauley

Patent number: 5453278Abstract: Improved Implant assemblies and methodologies provide immuno-protection for implanted allografts, xenografts, and isografts. The assemblies and methodologies establish an improved boundary between the host and the implanted cells. The boundary structure is laminated, combining elements having different characteristics beneficial to the survival of the implanted cells. Filaments of adhesive material lay in between the elements. The filaments of adhesive material have been melted in place by the application of heat and solidified in place by cooling to secure the elements together into a composite laminated structure.Type: GrantFiled: January 28, 1994Date of Patent: September 26, 1995Assignee: Baxter International Inc.Inventors: Eddie K.
