Abstract: | Due to the relatively limited amount of work done to date on developing prosthetic vein (as opposed to cardiac) valves, advances
in this topic require progress in three distinct areas: 1) improved device design, 2) relevant device testing conditions,
and, 3) appropriate parameters for evaluation of results. It is the purpose of this paper to address two of these issues (#2
and #3) by: 1) performing a study of normal volunteers to quantify the anatomy and hemodynamic features of healthy venous
valves, 2) construction of a 2-step, in vitro testing procedure, which simulates both physiologic and postural conditions seen in the lower extremity venous system, and,
3) defining several modified and new parameters which quantify dynamic valve characteristics. |
