Abstract
A catheter configured to dynamically compensate for the impact of internal and external forces that act upon the catheter during use is disclosed. The catheter may include sensors configured to measure received forces on control cables that extend within the catheter. A controller, coupled to the sensors, may record received force measurements associated with a working position of a distal end of the catheter. The controller may monitor subsequently received forces to identify force variances that may deflect the distal end of the catheter from its working position and may apply a driving force to one or more of the control cables to minimize the force variances. Monitoring received forces during use and applying compensating drive forces may reduce deflection of the distal end of the catheter, increasing the accuracy and precision of an annuloplasty procedure while minimizing potential damage to cardiac tissue.
