Abstract
A coated gut suture is prepared by applying a moisture-retaining substance to the gut suture, followed by coating the suture with a synthetic bioabsorbable polymer. A particularly useful moisture-retaining substance is glycerol. The synthetic bioabsorbable polymer contains a epsilon-caprolactone as the major constituent. The gut suture can be packed in the absence of conventional tubing fluid while retaining flexibility, pliability, and resistance to fray.
