Our engineers have contributed to over 200 patents and launched more than a dozen successful products. We've solved many problems with innovative solutions such as catheters to heart pumps and everything in between.  Check out some of our work and get in touch.




Vortex is a catheter that vacuums out fresh, soft thrombi or emboli that have accumulated in the blood and need to be removed.

Cruzar Houdini is a 5Fr catheter that allows the doctor to cross a total occlusion with unprecedented speed.



RAP enables patients born with weak or non-existent right ventricles in their heart to live longer, healthier and better lives.


We're located in a 4100 square foot facility right off the 101 in the green-roofed industrial park.  Our building faces Brittan Avenue, about 1/2 block off Industrial Road. We'd love for you to stop by, meet the team and see where the magic happens.
