Abstract:

A method of providing hemostasis of bleeding tissue. A flexible bioresorbable foam is formed that consists essentially of carboxymethylcellulose. The flexible bioresorbable foam is crosslinked. Chain scission is performed on the crosslinked flexible bioresorbable foam to provide the flexible bioresorbable foam with a selected in-vivo residence time of between about 3 days and about 14 days. Hemostasis is caused by applying the flexible bioresorbable foam to bleeding tissue. The flexible bioresorbable foam is resorbed in-vivo. The selected in-vivo residence time is a time between the flexible bioresorbable foam being applied to the tissue and the flexible bioresorbable foam having been substantially completely absorbed into the tissue.
