Supports Delrin durability in this case; leaves open prospective validation before clinical consideration.
Does Delrin provide acceptable bio-compatibility and durability as an implant material for valve occluders?
Delrin is an acceptable material for heart valve occluders with excellent bio-compatibility and durability, provided its propensity to absorb moisture is appropriately managed.
