US Patent:

7472604, Jan 6, 2009

Filed:

Sep 22, 2004

Appl. No.:

10/947644

Inventors:

Michael R Moreno - Coral Springs FL, US

Assignee:

Bose Corporation - Framingham MA

International Classification:

G01N 3/20

US Classification:

73849, 73862391, 73841

Abstract:

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.
