Patent number: 6531147Abstract: An improved barrier or drug delivery system which is highly adherent to the surface to which it is applied is disclosed, along with methods for making the barrier. In the preferred embodiment, the system is compliant, in that it is capable of conforming to the three dimensional structure of a tissue surface as the tissue bends and deforms during healing processes. The barrier or drug delivery systems is formed as a polymeric coating on tissue surfaces by applied a polymerizable monomer to the surface, and then polymerizing the monomer. The polymerized compliant coating preferably is biodegradable and biocompatible, and can be designed with selected properties of compliancy and elasticity for different surgical and therapeutic applications.Type: GrantFiled: November 7, 2001Date of Patent: March 11, 2003Assignee: Focal, Inc.Inventors: Amapreet S. Sawhney, Michelle D. Lyman, Peter K. Jarrett, Ronald S. Rudowsky

Patent number: 6451928Abstract: Provided is a crosslinking agent which is the ungelled reaction product of a polyester polyol and an aminotriazine compound having one or less non-alkylated NH bond per triazine ring. The polyester polyol is the reaction product of a cycloaliphatic polyol and a cyclic polycarboxylic acid or anhydride. The crosslinking agent is essentially free of hydroxyl functionality and has a glass transition temperature of at least 10° C. Further provided is a powder coating composition including a solid particulate film-forming mixture of a polymer containing reactive functional groups and having a Tg of at least 30° C., and the crosslinking agent. Additionally provided is a multi-layer composite coating composition having a basecoat layer deposited from a basecoat film-forming composition and a topcoat over the basecoat deposited from the previously described powder coating composition. Coated substrates are also provided.Type: GrantFiled: September 21, 2000Date of Patent: September 17, 2002Assignee: PPG Industries Ohio, Inc.Inventors: Ronald R. Ambrose, Anthony M.

Publication number: 20010046481Abstract: Poly(ethylene glycol) carbamate derivatives useful as water-soluble pro-drugs are disclosed. These degradable poly(ethylene glycol) carbamate derivatives also have potential applications in controlled hydrolytic degradation of hydrogels. In such degradable hydrogels, drugs may be either trapped in the gel and released by diffusion as the gel degrades, or they may be covalently bound through hydrolyzable carbamate linkages. Hydrolysis of these carbamate linkages releases the amine drug at a controllable rate as the gel degrades.Type: ApplicationFiled: April 21, 2001Publication date: November 29, 2001Applicant: Shearwater CorporationInventors: Michael David Bentley, Xuan Zhao

Patent number: 6214966Abstract: PEG and related polymer derivatives having weak, hydrolytically unstable linkages near the reactive end of the polymer are provided for conjugation to drugs, including proteins, enzymes, small molecules, and others. These derivatives provide a sufficient circulation period for a drug-PEG conjugate and then for hydrolytic breakdown of the conjugate and release of the bound molecule. In some cases, drugs that previously had reduced activity when permanently coupled to PEG can have therapeutically suitable activity when coupled to a degradable PEG in accordance with the invention. The PEG of the invention can be used to impart water solubility, size, slow rate of kidney clearance, and reduced immunogenicity to the conjugate. Controlled hydrolytic release of the bound molecule in the aqueous environment can then enhance the drug delivery system.Type: GrantFiled: September 25, 1997Date of Patent: April 10, 2001Assignee: Shearwater CorporationInventor: J.
