WALTHAM, Mass., March 30 /PRNewswire/ -- Confluent Surgical, Inc., today announced that it has completed a $23 million Series D round of venture funding, led by Three Arch Partners of Portola Valley, CA.

Mark Wan, a founding Partner at Three Arch Partners, who will be joining Confluent's Board of Directors stated, "We are excited about Confluent Surgical, as it heads into U.S. commercialization of its lead product DuraSeal, which will be the first surgical sealant approved in the U.S. for cranial surgery. Additionally, Confluent has a rich portfolio of surgical sealant and adhesion barrier products that we believe will cement it as a leader in the emerging field of biosurgery."
