Patents

Unlike all other VADs, the TORVAD is based on a completely new type of two-piston, valveless pumping technology that has resulted in six issued patents. All patents have been filed as collaborative patents with The University of Texas System as assignee and are exclusively licensed to WCS through an existing license agreement. The IP also covers non-biomedical applications of the pump in other fields such as space exploration, cryogenics, petroleum engineering, and food services. In addition, we maintain critical trade secrets related to techniques for manufacturing and assembling the TORVAD system that provide an additional level or protection for our technology.
