Abstract: Biocompatible polyarylates of tyrosine-derived diphenol compounds and poly(alkylene oxide) dicarboxylic acids, articles formed therefrom and therapeutic uses are disclosed.

Abstract: A radio-opaque dihydroxy compound substituted with at least one bromine or iodine atom. Radio-opaque medical implants and drug delivery devices and methods for therapeutic site-specific or systemic drug delivery comprising implanting in the body of a patient are also disclosed.

Abstract: Compounds exhibiting angiogenic properties incorporating the structure of Formula I: R3—NH—NH—C(?O)—R2—P—R1??(I) wherein P is a water-soluble, biodegradable polymer, R1 is hydrogen, lower alkyl, lower alkoxy or —R2—C(?O)—NH—NH—R3; each R2 is independently —CH2—, —NH— or O; and each R3 is independently hydrogen or a residue of a naturally occurring alpha-L-amino acid or dipeptide thereof. Polymer networks crosslinked with hydrazide compounds are also disclosed, together with implantable medical devices incorporating the compounds and crosslinked polymers, and angiogenesis-promoting treatment methods, including wound-treatment methods.

Abstract: Preferred embodiments relate to compositions of inherently radiopaque, biocompatible, bioresorbable polymeric particles and methods of using them for embolizing a body lumen.

Abstract: A method for treating pulmonary hypertension and other diseases involving a defect in collagen metabolism, by administration of an effective amount of a liposome encapsulated copolymer conjugate antifibrotic composition, is disclosed. The antifibrotic agent is preferably proline analogs, such as cis-4-hydroxy-L-proline (CHOP), 3,4-dehydro-DL-proline (DHP), (R)-(−)-2-thiazolidine-4-carboxylic acid (THP), and (S)-(−)-2-azetidinecarboxylic acid (ACA). Consistent, high loadings (>90%) of the antifibrotic agent are achieved by first forming a dipeptide with L-lysine, after which the dipeptide is copolymerized with the polymer component to form the copolymer conjugate. The polymer is preferably poly(ethylene glycol) having a weight average molecular weight of from about 500 to about 15,000. Efficient delivery and consistent release of the antifibrotic agent inhibits collagen accumulation and treats the diseases involved.

Abstract: A method for treating pulmonary hypertension and other diseases involving a defect in collagen metabolism, by administration of an effective amount of a liposome encapsulated copolymer conjugate antifibrotic composition, is disclosed. The antifibrotic agent is preferably a proline analog, such as cis-4-hydroxy-L-proline (cHyp). Consistent, high loadings (>98%) of the antifibrotic agent are achieved by first forming a dipeptide with L-lysine, after which the dipeptide is copolymerized with the polymer component to form the copolymer conjugate. The polymer is preferably poly(ethylene glycol) having a weight average molecular weight of from about 500 to about 15,000. There is thus provided the efficient delivery and rateable release of the antifibrotic agent to inhibit collagen accumulation and thereby treat the diseases involved.

Abstract: A multi-dimensional copolymer array of a plurality of copolymers, polymerized from at least two independently variable sets of monomers, wherein the polymerization is characterized by:

Abstract: A novel series of articles useful as medical devices, implants and protheses are provided which utilize poly(iminocarbonate) polymeric matrices. These articles are biocompatible, have excellent mechanical properties and degrade into non-toxic residues after introduction in vivo. The articles may be formed in any desired dimensions and configuration and may take specific shape as biodegradable sutures or as orthopedic appliances such as bone plates and the like.

Abstract: A novel bioerodible polymeric composition is provided comprising a plurality of monomer units of two or three amino acids which are polymerized via hydrolytically labile bonds at their respective side chains rather than at the amino or carboxylic acid terminals by amide bonds. Such polymers are useful for controlled release applications in vivo and in vitro for delivery of a wide variety of biologically and pharmacologically active ligands.
