Abstract: A fatigue testing system (100) provides simultaneous cycle testing for a plurality of prosthetic devices under simulated physiological loading conditions. A plurality of sample holders (129) containing test samples (130) of prosthetic devices is positioned between a distribution chamber (126) and a return fluid chamber (136) to form an integrated test chamber (106). A reciprocating linear drive motor (105) operates a rolling bellows diaphragm (115) to cyclically pressurize fluid within the test chamber (106) and drive the pressurized fluid through the prosthetic devices (130) being tested. The test chamber (106) defines a return flow conduit (124) in fluid communication with each of the sample holders (129), the return fluid chamber (136), and the distribution chamber (126). Compliance chambers (135) and throttle valves (132) associated with each of the sample holders (129) regulate the pressure gradient and back pressure across the prosthetic devices (130) being tested.

Abstract: The present invention provides controlled expansion endoluminal prostheses and methods for their deployment and expansion. The present stent-grafts (10) generally comprise a radially expansible tubular frame (12) and a plastically expansible liner (74) on the frame. Either the frame (12) or the liner (74) includes a reinforcing element (96) which limits expansion of the stent-graft (10) at a predetermined expanded size. In some embodiments, the reinforcing element (96) restrains the frame (12), for example, by limiting the circumferential diagonals of perforations on a perforate frame structure (12). Generally, however, the reinforcing element (96) is included in the liner (74) as circumferentially oriented yarn (22). A particularly advantageous liner (74) includes composite circumferential yarns (130) having in-expansible fibers (134) wrapped around an expansible fiber (132), such as a partially oriented yarn, PTFE, or the like.

Abstract: Prostheses are fatigue tested using an apparatus under simulated physiological loading conditions. A fluid housing defines an entrance chamber having fluid outflow ports and an exit chamber having opposing fluid inflow ports and a central flow conduit in communication with the entrance chamber and the exit chamber. A plurality of housing tubes into which prosthesis are deployed may extend between the fluid outflow and inflow ports. Alternatively, tubular prostheses may be connected directly between the inflow and outflow ports. A reciprocating linear drive pump having a flexible diaphragm is provided to cyclically pressurize fluid through a common closed loop within the fluid housing and drive the pressurized fluid through the prosthesis being tested. The test system is capable of rotation independent of the motor drive for accurate diameter measurements of all test samples at elevated frequencies.
