  • Patent number: 6130271
    Abstract: A deformable surgical repair device is manufactured from a block or graft copolymer. The copolymer comprises a plurality of first linkages selected from the group consisting of glycolic acid ester and lactic acid ester linkages, and mixtures thereof, and a plurality of second linkages selected from the group consisting of 1,3-dioxan-2-one; 1,4-dioxan-2-one and .epsilon.-caprolactone linkages. The plurality of first linkages comprises at least about 50 up to about 90 mole percent of the copolymer. In an alternative Claim, the deformable surgical repair device is manufactured from a blend of a first and a second absorbable polymer. The first absorbable polymer comprises a plurality of linkages selected from the group consisting of glycolic acid ester and lactic acid ester linkages, and mixtures thereof. The second absorbable polymer comprises a plurality of linkages selected from the group consisting of 1,3-dioxan-2-one; 1,4-dioxan-2-one and .epsilon.-caprolactone linkages.

  • Patent number: 4068757
    Abstract: Natural or synthetic rubber surgical elements such as tubing, catheters, drains and gloves are "lubricated" so as to prevent sticking during storage, and permit easier emplacement, such as putting on the gloves by a surgeon or nurse, by applying to the surface of the rubber elementA finely divided biodegradable powder consisting essentially ofAn enzymatically degradable form of poly(N-acetyl-D-glucosamine) selected from the group consisting ofPoly[N-acetyl-6-O-(carboxymethyl)-D-glucosamine],Poly[N-acetyl-6-O-(2'-hydroxyethyl)-D-glucosamine],Poly[N-acetyl-6-O-(ethyl)-D-glucosamine], andPoly(N-acetyl-D-glucosamine) itselfThis powder is readily absorbed by living tissue without deleterious tissue reaction, thus minimizing tissue reaction from the transfer of the powder from the element such as a glove to internal sites in a subject. The gloves may be packaged in a strippable laminate package. The polymers are derived from chitin.
