Compositions And Methods For Dissolving Body Calculi

View page
US Patent:
52449130, Sep 14, 1993
Filed:
Nov 19, 1991
Appl. No.:
7/794544
Inventors:
Stephen L. Coulter - Irvine CA
Kenneth G. Mayhan - Irvine CA
Christy L. H. Oviatt - Mission Viejo CA
Steven R. Morehead - Riverside CA
Assignee:
Baxter International Inc. - Deerfield IL
International Classification:
A61K 3144
A61K 3114
US Classification:
514358
Abstract:
Compositions and methods for dissolving calculi deposits in humans are disclosed. The compositions include solutions of quaternary ammonium salts and are particularly effective for the contact dissolution of pigment portions of biliary tract calculi such as gallstones. The solutions preferably further include mineral chelating agent and disulfide bond cleaving agent to aid in deaggregating mineral components and glycoprotein components of calculi.

Assembly For Inhibiting Microbial Growth In Collected Fluid

View page
US Patent:
48634450, Sep 5, 1989
Filed:
Jul 30, 1984
Appl. No.:
6/635772
Inventors:
Kenneth G. Mayhan - Irvine CA
Bernice I. Romo - Alhambra CA
Robert L. Murtfeldt - Redondo Beach CA
William J. Bertrand - Sunnymeade CA
Assignee:
Baxter Travenol Laboratories, Inc. - DE
International Classification:
A61M 100
US Classification:
604317
Abstract:
An assembly for inhibiting microbial growth in collected body fluid includes a reservoir for collecting the fluid, and a tablet in the reservoir, which tablet dissolves in the collected fluid to produce hydrogen peroxide in an amount sufficient to inhibit microbial growth in the collected fluid. The tablet is partially coated with an insoluble coating which leaves a portion of the tablet uncoated to provide a constant surface area exposed to the collected body fluid, which surface area is of a size to provide sufficient hydrogen peroxide for inhibition of microbial growth.

Method Of Dissolving Cholesterol-Rich Calculi With Short Chain Halogenated Organic Solvents And Cosolvents

View page
US Patent:
49940252, Feb 19, 1991
Filed:
Aug 29, 1989
Appl. No.:
7/400212
Inventors:
Paul DeAntonio - Westminster CA
Kenneth G. Mayhan - Irvine CA
John T. Sorensen - Costa Mesa CA
Assignee:
Baxter International Inc. - Deerfield IL
International Classification:
A61M 100
US Classification:
604 28
Abstract:
Disclosed is a method for dissolving cholesterol-rich calculi, most preferably gallstones in vivo, comprising contacting the calculus with a fluid compound of the formula R-X, R having 2 to 4 carbon atoms with substituents consisting of hydrogen of halogen, X being halogen, and wherein if X is fluorine, at least one substituent is selected from the group consisting of hydrogen, chlorine, bromine, or iodine. Usually R-X is 2-bromo-2-chloro-1,1,1-trifluoroethane (also referred to as Halothane. ) Other compounds of particular interest are 2-chloro-1,2,-dibromo-1,1,2-trifluoroethane, 1-bromo-2-chloro-1,1,2-trifluoroethane, 2,3-dibromo-1,1,1-trifluoropropane, 2-iodo-1,1,1-trifluoroethane, 1,2-dichloro-1,1-difluoroethane, 1,1,2-trichloro-2,3,3-trifluorocyclobutane, hexafluoro-1,1,3,4,-tetrachlorobutane, 1,1,1-trichlorotrifluoroethane, and 1,2-dibromo-tetrafluoroethane. Furthermore, Halothane and MtBE in combination effectively dissolve cholesterol-rich calculi. Finally, dissolution can be enhanced by adding to the dissolution solvent up to about 50 percent by volume of a lower alcohol.

Compositions Useful For Removing Products Of Metal Corrosion

View page
US Patent:
55341772, Jul 9, 1996
Filed:
Feb 14, 1992
Appl. No.:
7/835665
Inventors:
Kenneth G. Mayhan - Irvine CA
International Classification:
C02F 500
US Classification:
510245
Abstract:
The present invention is directed to compositions useful for removing products of metal corrosion from corroded metals which consists essentially of an aqueous liquid solution of malonic acid, a surfactant and an organic solvent selected from the group consisting of formamide, dimethylformamide, and dimethylsulfoxide.

Fluorocarbon Grafting Of Polymeric Substrates

View page
US Patent:
45956324, Jun 17, 1986
Filed:
Feb 6, 1984
Appl. No.:
6/577300
Inventors:
Kenneth G. Mayhan - Irvine CA
Robert A. Janssen - Eden Prairie MN
Roger F. Drake - Costa Mesa CA
Assignee:
American Hospital Supply Corporation - Evanston IL
International Classification:
B32B 2728
B32B 2516
US Classification:
428409
Abstract:
A process for modifying the surface of a preformed polymeric substrate to impart lubricity and other desired properties thereto, without at the same time significantly altering the bulk properties of the substrate, by epoxidizing the substrate's surface and reacting the epoxide groups so formed with a fluorocarbon capable of cleaving the epoxide rings and covalently bonding thereto. The article so formed is also disclosed.

Process For Graft Copolymerization Of A Pre-Formed Substrate

View page
US Patent:
45899649, May 20, 1986
Filed:
Feb 14, 1984
Appl. No.:
6/580119
Inventors:
Kenneth G. Mayhan - Irvine CA
Robert A. Janssen - Eden Prairie MN
William J. Bertrand - Sunnymead CA
Assignee:
American Hospital Supply Corporation - Evanston IL
International Classification:
C08F29118
US Classification:
522 85
Abstract:
A process for modifying the surface characteristics of a pre-formed polymeric substrate to impart hydrophilicity, hydrophobicity, or other desired properties thereto, by peroxidizing the surface of the substrate and then allowing the active sites along the polymer chains to generate free radicals which induce graft polymerization of a suitable ethylenic monomer (or other ethylenically-unsaturated compound) onto the surface of the substrate is described. Such graft copolymerization is undertaken in the presence of variable valence metal ions in a reduced state under acidic conditions and at selected reaction times and relatively low temperatures, and ideally in the presence of squarate ions (diketocyclobutenediol) to control the physical characteristics of the surface graft and to restore the metal ions to their lower valence state without at the same time producing deleterious by-products.
