MitrAssist has developed an approach to treating patients with life-threatening mitral regurgitation (MR) that involves neither repair nor replacement. Instead, the companys proprietary valve implant is placed on top of the natural valve to work in unison with it and to enhance valve functionality. MitrAssists valve-in-valve approach overcomes the various challenges of MR and offers an alternative treatment solution for all MR patients. Made from biomedical and biological materials, MitrAssists valve offers improved biocompatibility and patient recovery time.
