Atritech closes $30mm round

Executive Summary

Medical device company Atritech raised $30mm through a late-stage venture round led by Thomas, McNerney & Partners. Split Rock Partners, Prism Ventures, Tullis-Dickerson, and Vector Group also participated in the financing. The company will use the funds to complete FDA review and then market launch of its Watchman closure device, designed to prevent stroke-causing blood clots from entering the circulatory system in patients with atrial fibrillation. The PROTECT AF clinical trials are comparing the device to warfarin drug treatment, the current standard of care.
