Abstract: Various embodiments concern a system for measuring a force on a catheter. The catheter can comprise a proximal segment, a distal segment, and an intermediary segment comprising at least one strut. Each strut can extend from the proximal segment to the distal segment. Each strut can be formed from a super-elastic metal alloy material, such as nitinol. The plurality of struts can be configured to resiliently support the distal segment with respect to the proximal segment while permitting relative movement between the distal segment and the proximal segment. The system can comprise control circuitry configured to measure, for each of the plurality of struts, a change in an electrical property of the super-elastic metal alloy material of the strut when the distal segment moves relative to the proximal segment to determine a magnitude and direction of the force.

Abstract: A catheter adapted to measure a contact force includes a proximal segment, a distal segment, a spring segment extending from the proximal segment to the distal segment, and at least one inductive sensor. The at least one inductive sensor includes a first plate of high magnetic permeability material disposed on the proximal segment, a second plate of high magnetic permeability material disposed on the distal segment opposite the first plate, at least one first coil disposed adjacent to the first plate between the first plate and the second plate, and at least one second coil disposed adjacent to the second plate opposite the first coil between the first plate and the second plate. The second coil is electrically connected in series with the first coil. The first coil and the second coil are configured to output a signal indicative of displacement between the first coil and the second coil.

Abstract: Various embodiments concerns a system for measuring a force within a body comprising a catheter, the catheter comprising at least one sensor and an element located within the catheter, the element displaceable within the catheter relative to the at least one sensor. The system further comprises control circuitry configured to measure, for each of the at least one sensor, a change in a resonance frequency of the sensor based on a change in distance between the sensor and the element, the change in distance responsive to the force. The control circuitry is further configured to calculate at least one parameter of the force based on the change in the resonance frequency, and output an indication of the at least one parameter of the force.

Abstract: Devices and systems for ultrasonically imaging anatomical structures and performing ablation therapy within the body are disclosed. A combined ablation and ultrasound imaging probe includes an ablation electrode tip including an ablation electrode configured for delivering ablation energy, and a number of ultrasonic imaging sensors configured for imaging the tissue surrounding the probe. The ultrasonic imaging sensors are supported within the interior of the tip via a tip insert, and deliver ultrasonic waves through acoustic openings formed through the tip. The tip insert separates an interior lumen within the tip into a proximal fluid chamber and a distal fluid chamber. During an ablation procedure, the ultrasonic imaging sensors can be tasked to generate a number of ultrasonic images that can be displayed on a user interface.
