A 2010 Malvern biotech startup is developing devices to close up catheter punctures, and a recent round of investment has closed up the gap in financing to help it get there.

Essential Medical raised $14.9 million in private stock just after two of its products, its flagship Manta as well as X-Seal, moved into clinical trials, according to a Philadelphia Business Journal report by John George.

Amzak Health led the monetary infusion and “will also provide additional expertise and experience to our board of directors as our company transitions to commercialization in Europe and the initiation of the U.S. clinical trial for our Manta product,” Essential Medical CEO and Co-Founder Greg Walters said in the article.

Essential Medical is eyeing a potential worldwide market worth $600 million in the next five years.

Other major investors include the local Ben Franklin Technology Partners of Southeastern Pennsylvania and Royal DSM’s DSM Venturing.
