Hansen Medical, Inc, headquartered in Mountain View, California, designs and manufactures medical robotics for positioning and control of catheter-based technologies that was founded in 2002 by Frederic Moll, M.D. to develop tools that manipulate catheters by combining robotic technology and computerized movement.

In 2005, Hansen bought EndoVia Medical Inc., a medical robotics company.

Later that year, Hansen Medical and Intuitive Surgical, another company founded by Moll, entered into a cross-licensing agreement that included Hansen's portfolio of 50 issued and pending patents and patent applications and Intuitive's 250 issued patents related to minimally invasive instruments and surgical robotics.

Hansen Medical went public in 2006, raising $75 million in its Initial Public Offering with two catheter systems under FDA review. The shares represented about 30% of the company.

In July 2016 it was acquired by Auris Surgical Robotics, and it was said to be a $80 million merger.
