Variable Friction Catheter

In cardiovascular interventions, Catheters are typically inserted in the radial or femoral artery and are navigated through the arteries to the heart, where the interventions are performed.  In order to safely reach the heart,  catheters  (and guidewires) used during these procedures need to be able to easily follow the curves in the  vascular  system,  while  creating  as  little  friction  as  possible to avoid damaging the blood vessel inner wall.  While low friction is beneficial during navigation, it makes holding the catheter at a specific location in open spaces, such as inside the heart, difficult during the execution of the surgical procedure. Thus, it limits the force transmission capability of the catheter. In this project, we look forward to developing a new variable friction catheter which can be modulated to have low friction while navigating and high friction while performing the surgical task to ensure optimal performance and outcomes in both cases.
