Heart Valve Leaflet Material - Testing Update
RUA Life Sciences (AIM: RUA), the holding company of a group of medical device businesses focused on the exploitation of the world's leading long-term implantable biostable polymer (Elast-Eon?), today provides an update on recent developments of the RUA leaflet composite.
The objective for RUA Structural Heart during 2023 was to evaluate heart valve leaflet material and compare the performance of 100% polymeric valves with the novel composite developed by the Group. The computational modelling of the composite material at the design stage suggested that its mechanical properties would be ideal for heart valve leaflets.
Testing undertaken by RUA has demonstrated:
· Flex fatigue stability over 400m cycles
· Durability as a heart valve leaflet over 200m cycles
· Remarkable tensile strength properties exceeding both base fabric and polymer
· Similar tensile strength in multiple directions
· Highly flexible allowing improved valve efficiency.
· Narrow crimping profile allowing TAVR benefits
· Retention of ElastEon blood contacting properties such as calcification and thrombogenicity.
· Material very stable with no delamination during testing and high tear resistance.
