Abstract
A vascular prosthesis tester (10) for inducing stresses upon a vascular prosthesis (22) having a channel extending through the vascular prosthesis is disclosed. The tester includes a pump (18) adaptable to pressurize a fluid disposed within the channel to induce a radial stress upon the vascular prosthesis. The tester may further include a bend applicator (16) operable to induce a bending stress, a torque applicator (12) operable to induce a torque, a linear force applicator (52) operable to induce a linear force, and/or a stop (28) for inducing a lateral push stress upon the vascular prosthesis. A method of fatigue testing a vascular prosthesis contained within a fluid conduit is also disclosed. The method includes injecting a fluid within the inner channel and inducing a torque, bending stress, linear stress, and/or later push stress upon the vascular prosthesis.
