A vascular prosthesis tester () for inducing stresses upon a vascular prosthesis () having a channel extending through the vascular prosthesis is disclosed. The tester includes a pump () 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 () operable to induce a bending stress, a torque applicator () operable to induce a torque, a linear force applicator () operable to induce a linear force, and/or a stop () 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.

An expandable, intraluminal tubular stent is provided for insertion and expansion within the lumen of a vessel. The stent includes a plurality of longitudinal struts. A series of arcuate or V-shaped end links are connected between the ends of the longitudinal struts. A series of deformable cross-links are circumferentially connected between adjacent longitudinal struts at a center portion of the longitudinal struts to permit the stent to be expanded from a first smaller diameter into a second larger diameter upon insertion into the vessel.
