Suture Retention Strength

Determination of the force necessary to pull a suture from the prosthesis or cause the wall of the prosthesis to fail.

Test Procedure

A suture is inserted 2 mm from the end of the stretched prosthesis through one wall of the prosthesis to form a half loop. The suture is pulled at the rate of 50 mm×min-1 to 200 m×min-1.
