Interfacial polymerization the reaction of monomers to form a polymer at the contact (interface) between two immiscible liquid layers. The monomers are dissolved in different layers, and only come into contact at the interface. Vicryl (polyglactin 910) is a copolymer formed by the polymerization of a mixture of purified lactide and glycolide (cyclic intermediates derived from lactic acid and glycolic acids) Nylon - synthetic polyamide polymer fiber Silk – a protein fibre produced by the silkworm larva which extrudes this fibre while synthesizing its cocoon (raw silk is white) Aneurysm - localized, blood-filled dilation (bulge) of a blood vessel caused by

Unformatted text preview: disease or weakening of the vessel wall. Anastomosis: The connection of normally separate parts or spaces so they intercommunicate. May be naturally occurring or artificially constructed E.g. it connects two blood vessels. Surgical Gut plain Lost within 7-10 days Surgical Gut Chromic Lost within 21-28 days Vicryl 60% after 2 weeks 30% at 3 weeks 0% at 30 days Dexon Same as Vicryl PDS (Polydioxanone) 70% at 2 weeks 50% at 4 weeks 25% at 6 weeks Nylon-Nylon will have much greater retention of tensile strength because it is not easily degraded by the body....
