Abstract
A fiber-based surgical implant stabilized against fraying, includes a thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, polymer material having a glass transition temperature or other thermally induced secondary conformational mobility threshold in the temperature range of from 20° C. to +170° C. Also disclosed is a corresponding fabric and methods of producing the implant and the fabric.
Claims20
A thermally crimped flat-knitted fabric of a biocompatible, optionally biodegradable, material stabilized against fraying, wherein the fabric comprises two or more layers of a flat-knitted thermally shrinkable polymer material having either a glass transition temperature or another secondary thermally induced conformational mobility threshold;
- two or more layers of the flat-knitted thermally shrinkable polymer material being joined to each other, each of the two or more layers having a warp and a weft and being crimped in a direction either along the weft or perpendicular to the weft, the two or more layers of the flat-knitted thermally shrinkable polymer material having one or more interlaced sections separated by one or more non-interlaced sections, wherein the interlaced section extends over the two or more layers of flat-knitted thermally shrinkable polymer material;
- a first cut edge at an area of abutment between the one or more interlaced sections and the one or more non-interlaced sections;
- and a second cut edge formed only in the non-interlaced section and in less than all of the two or more layers of flat-knitted thermally shrinkable polymer material.
