Abstract
The present invention is directed to implantable bioabsorbable non-woven self-cohered web materials having a high degree of porosity. The web materials are very supple and soft, while exhibiting proportionally increased mechanical strength in one or more directions. The web materials often possess a high degree of loft. The web materials can be formed into a variety of shapes and forms suitable for use as implantable medical devices or components thereof.
Claims10
A medical device comprising a substantially rectangular, implantable, pledget material releasably attached along opposite sides of said rectangular pledqet material to a porous, bioabsorbable, non-woven web having a percent porosity greater than ninety to form a substantially tubular shape;
- said porous web having melt-formed continuous filaments intermingled to form a porous web wherein said filaments are self-cohered to each other at multiple contact points, wherein said filaments comprise at least one semi-crystalline polymeric component covalently bonded to or blended with at least one amorphous polymeric component, wherein the filaments possess partial to full polymeric component phase immiscibility when in a crystalline state,
- wherein said porous web is dimensioned to retain said pledqet material on a surgical stapler.
