Composite surgical material. |
摘要 |
<p>A composite surgical material comprising a collagen matrix reinforced by a layer of a synthetic bioabsorbable material such as polylactide/polyglycolide or oxidised regenerated cellulose, and wherein oil droplets are dispersed in the collagen matrix. The oil droplets comprise 1% to 75% of the weight of the composite and result in improved leak-proofing of the composite. The composite, in the form of a sheet or a tube, is especially useful as a temporary, fully bioabsorbable prosthesis, for membranes or blood vessels where a highly leak-proof prosthesis is required. The invention also provides a method of making a composite surgical material comprising the steps of: providing a layer of a synthetic bioabsorbable material; providing a dispersion of collagen in an oil-in-water emulsion; coating at least one face of the layer of synthetic bioabsorbable material with the said dispersion; and drying the composite material thus obtained. <IMAGE></p> |
