Intravascular imaging system with remedial action for torque cable
A recently granted patent (Publication Number: US11918761B2) discloses a pullback and rotation unit designed for axially translating and rotating a torque cable within an elongate outer sheath of a catheter. The unit comprises a housing with a longitudinal axis, a rotor mounted to rotate and linearly translate within the housing, and a plurality of sensors on the rotor to measure the axial force exerted by the torque cable. The system includes a controller that automatically triggers a remedial action when the measured force exceeds a predetermined threshold, ensuring the rotor retracts a predetermined distance to relieve the force without causing damage to the outer sheath. The design aims to enhance the safety and efficiency of intravascular imaging procedures by providing real-time monitoring and control of the torque cable's movement.
Furthermore, the patent includes claims for a method of imaging a vessel using the described intravascular imaging catheter system. The method involves coupling the catheter with the pullback and rotation unit, inserting it into the vessel, and translating the imaging tip distally by manipulating the rotor within the housing. The system's sensors continuously monitor the axial force applied to the rotor, triggering remedial actions when necessary to prevent damage to the outer sheath. By ensuring the rotor retracts a predetermined distance when excessive force is detected, the method aims to maintain the integrity of the catheter system during imaging procedures. Overall, the patented technology offers a sophisticated solution for improving the precision and safety of intravascular imaging by providing automated control mechanisms based on real-time force measurements.
