SentiARSentiAR announced today that it closed an oversubscribed Series A financing round that brought in proceeds of $5.1 million.

St. Louis-based SentiAR said in a news release that the money will allow it to accelerate the innovation of its mixed reality CommandEP system for surgical visualization.

CommandEP is designed to provide physicians with holographic visualization through mixed reality. SentiAR touts it as the first FDA 510(k)-cleared guidance system of this kind to be used during invasive cardiac procedures. It is also used in other types of surgery.

TechWad Holding joined the financing round as the company’s newest investor, while BioGenerator, Cultivation Capital, VCapital, Neue Fund, QRM Capital and Keiretsu Forum also contributed.

“We are thrilled with the financial and operational support from TechWald Holding and particularly pleased to welcome TechWald partner, Shlomo Shpun, as a valued member of our board of directors,” SentiAR CEO Berk Tas said in the release. “Mr. Shpun is a reputable industry expert in electrophysiology and has been previously involved in the development of several major EP technologies. With several decades of industry expertise, Mr. Shpun will actively contribute to SentiAR’s board.”
