A stiffening member (25) formed from substantially nonresilient material fit about the valve body exterior wall to provide structural integrity to the valve body (19). Stresses which are normally applied to the heart valve body during the opening and closing of the valve are absorbed or ...
and Teflon (polytetrafluoroethylene), are utilized to create the suture ring. These polymers have reduced clotting and foreign body response, making them ideal for use in a heart valve. Despite careful material selection, mechanical heart valves are still associated with a risk of thrombogenicity....
Valve developed byCryoLifeis a newer-generation, FDA-approved heart valve made of a unique material and with unique design characteristics compared with earlier generations of mechanical heart valves. It is claimed that in a prospective randomizedclinical trial, On-X Aortic Valve patients with a ...

Proof testing of mechanical heart valves A method and apparatus for proof testing an assembled mechanical heart valve prosthesis having a valve body and at least one movable occluder wherein at least one of the components has a surface of nonmetallic crystalline material, such ... JP Ritz,AD Ha...
Design and simulation of mechanical heart valve prostheses. Although heart valve replacement is among the commonest cardiovascular surgical procedures, their outcome is often difficult to predict. One of the reasons is the design and choice of material of construction of the prostheses. This thes.....
The Dacron sewing ring material of the St. Jude Medical mechanical heart valve (St. Jude Medical, Inc., St. Paul, Minn.) was passively impregnated with rifampicin (60 mg/ml) both in its unsealed state and after sealing by the methods of preclotting in blood, autoclaving in blood, and ...
