Aspects of the present disclosure are directed toward systems and methods for detecting force applied to a distal tip of a medical catheter. A medical catheter includes a deformable body near a distal tip of the catheter that 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.

Force sensing catheter system

Various embodiments of the present disclosure can include flexible catheter tip. The flexible catheter tip can include an inboard understructure that defines a tip longitudinal axis, wherein the inboard understructure can be formed from a first continuous element that includes a first rectangular cross-section. An intermediate inboard covering can be disposed about the first continuous element that forms a distal portion of the inboard understructure. An outboard understructure can extend along the tip longitudinal axis, wherein the outboard understructure can be formed from a second continuous element that includes a second rectangular cross-section. An intermediate outboard covering can be disposed about the second continuous element that forms a distal portion of the outboard understructure.
