TVA Medical Raises $9.5 Million to Advance Minimally Invasive Therapy for End-Stage Renal Disease

AUSTIN, Texas, June 10, 2013 /PRNewswire/ -- TVA Medical, Inc. (TVA Medical), a medical device company developing minimally invasive therapies for End-Stage Renal Disease (ESRD), announced today that it received $9.5 MM in Series B financing.  S3 Ventures led the round and was joined by TriStar Technology Ventures and existing investor, Santé Ventures.  The funding will be used to further validate the Company's endovascular technology and complete additional clinical studies to support worldwide regulatory approvals.


TVA Medical is developing a minimally invasive catheter-based system that allows physicians to create an arterio-venous fistula (joining an artery to a vein) to deliver hemodialysis to patients suffering from kidney failure. "The results to date suggest that durable arterio-venous fistulas can be safely and reproducibly created without surgery. The potential to significantly improve care for renal failure patients while decreasing the cost of dialysis delivery is substantial," said William (Billy) E. Cohn, MD, Founder of TVA Medical, and Director of Minimally Invasive Surgical Technology at the Texas Heart Institute at St. Luke's Episcopal Hospital in Houston, Texas.  The technology is being studied outside of the United States and is currently not available in the U.S.  The Company intends to seek Food and Drug Administration clearance in the future. 

"Over two million patients worldwide receive chronic hemodialysis therapy and this population is growing at 8% per year. TVA Medical's technology addresses a significant unmet medical need and has the potential to change the way hemodialysis patients are treated," said Brian R. Smith, Managing Director at S3 Ventures.        

The surgical arterio-venous fistula (AV fistula) is the current gold-standard, but this form of access is plagued by high failure rates and frequent revisions resulting in enormous healthcare cost.  "A percutaneous AV fistula system has the potential to improve patient outcomes and drive cost out of the healthcare system," said Gerald A. Beathard, MD, PhD, pioneer of interventional nephrology from Houston, TX.

"The U.S. healthcare system spends over $47 billion annually to treat end-stage renal disease, and despite the tireless efforts of healthcare providers, only 51% of dialysis patients are still alive three years after starting therapy.  As a medical device company we believe there is an opportunity to improve outcomes for these patients while reducing healthcare costs," said Adam L. Berman, CEO of TVA Medical. The market opportunity for TVA Medical's technology exceeds $1 billion annually.
