Document Type and Number:
WIPO Patent Application WO/2012/124562
Kind Code:
A1
Abstract:
The present invention is characterized by providing a bioresorbable suture thread having high flexibility, high tensile strength, knot strength, a shape that is maintained without a plurality of threads unraveling even at cut ends or torsion inflection points, excellent knot retention, and excellent production efficiency. The present invention is a bioresorbable suture thread comprising: a core thread comprising a bioresorbable, low fusion-point component; and a plurality of wound threads comprising bioresorbable, high fusion-point components, wound around the core thread. The bioresorbable suture thread has a structure wherein the core thread and the wound threads are adhered by the core thread that has been melted and fused by heat processing.
