TAVI has been developed as a means to treat aortic valve disease using a minimally invasive approach. Symetis has developed ACURATE TA and ACURATE TF products for the estimated $2 billion TAVI market. Symetis will incorporate Endoluminal Sciences’ active anti-paravalvular leak technology into its ACURATE TAVI™ product line with the goal of continuing to reduce paravalvular leak in patients undergoing TAVI procedures.

Paravalvular leak (PVL) occurs in the majority of patients undergoing TAVI and is a key determinant of increased post-procedural mortality. Since the publication of Kodali et al. in 2012, reduction of PVL has been identified as the main challenge to unleashing the full potential of the TAVI market. Several companies in the TAVI market already have programs to partially address this challenge using various passive solutions. This includes Symetis’ “Self-Sealing” technology that has been designed into the ACURATE TAVI™ products and has contributed to strong clinical results. Endoluminal Sciences has developed a unique solution to actively reduce PVL in transcatheter heart valve prostheses based upon the company’s proprietary swelling polymer and membrane technology.

According to Dr. Raj Makkar, MD (Cedars Sinai, Los Angeles), a member of Endoluminal Sciences’ clinical advisory team: “Reducing paravalvular leak is critical for long-term success of TAVI. Endoluminal Sciences’ active anti-paravalvular leak technology is a novel solution to this problem.”

“By combining Symetis’ Self-Sealing TAVI design with Endoluminal Sciences’ active anti-PVL technology, Symetis is establishing its ZeroLeak™ vision: offering superior clinical outcomes by eliminating relevant PVL for all patients, while maintaining ACURATE’s reputation for uncomplicated valve delivery,” said Jacques Essinger, Ph.D, CEO of Symetis.

Stéphane Delaloye, VP R&D at Symetis added: “Our initial in-vitro evaluation confirmed that Endoluminal Sciences’ sealing technology has the potential to address PVL in the most challenging calcification patterns. Mounting this novel technology onto our ACURATE TAVI™ platform will allow us to further reduce PVL for the benefit of all patients.”

Ashish Mitra, CEO & Founder of Endoluminal Sciences said, “We are very excited to partner with Symetis and to be part of the foundation of a unique 3rd generation of TAVI devices that will improve patient outcomes. We believe the combination of ACURATE TAVI™ products and Endoluminal Sciences’ active anti-PVL technology will prove to be a winning combination.”
