There's no question that both 2015 and 2016 were blockbuster years for surgical sealant maker Cohera Medical Inc. During the two-year period, the company brought in significant funding and received its first FDA device approval. The private company is getting off to a strong start in 2017 with the enrollment of the first patient in the clinical trial for the Sylys surgical sealant. The company said Sylys will serve as an adjunct to standard closure techniques in colorectal and ileorectal anastomosis procedures.
