Venostent Inc. has completed $16 million in series A financing to support a U.S. pivotal trial for bioabsorbable wraps designed to improve outcomes for hemodialysis patients suffering from end-stage renal disease (ESRD). This comes after Venostent was granted an FDA investigational device exemption (IDE) to begin its U.S. Selfwrap-assisted arteriovenous fistula study and breakthrough device designation of its technology awarded last year.
