  • Publication number: 20190388033
    Abstract: Aspects of the present disclosure are directed toward systems and methods for calibrating and detecting force applied to a distal tip of a medical catheter. Some embodiments are directed toward a medical catheter with a deformable body near a distal tip of the catheter that deforms in response to a force applied at the distal tip. A force sensor detects various components of the deformation and processor circuitry, based on the detected components of the deformation, determines a force applied to the distal tip of the catheter and accounts for the effects of a bending moment.

  • Publication number: 20190307505
    Abstract: Aspects of the present disclosure are directed toward systems and methods for detecting force applied to a distal tip of a medical catheter. In some embodiments, a medical catheter with a deformable body near a distal tip of the catheter deforms in response to a force applied at the distal tip, and a sensor detects various components of the deflection. Processor circuitry may then, based on the detected components of the deformation, determine a force applied to the distal tip of the catheter.
