Abstract: Embodiments herein relate to systems and methods for intravascular lesion disruption. In an embodiment, a catheter system for imparting pressure to induce fractures upon a vascular lesion within or adjacent a blood vessel wall is included. The system includes a catheter configured to advance to a vascular lesion, the catheter including an elongate shaft that defines at least a first orifice for fluid flow; a balloon, coupled to the elongate shaft, that surrounds the first orifice where the balloon can expand from a collapsed configuration suitable for advancing the catheter through a patient's vasculature to a first expanded configuration suitable for anchoring the catheter in position relative to a treatment site; and a propulsion system configured to propel a fluid from the first orifice toward the balloon wall to create an inertial impulse in a vessel wall to transfer momentum to the vascular lesion. Other embodiments are also included herein.

Abstract: An ultrasound catheter is adapted for placement within a blood vessel having a vessel wall and is adapted for treating a vascular lesion within or adjacent the vessel wall. The ultrasound catheter includes an elongate shaft extending from a distal region to a proximal region and an ultrasound transducer that is disposed within the distal region of the elongate shaft, the ultrasound transducer adapted to impart near-field, acoustic pressure waves upon the vascular lesion in order to mechanically modify the vascular lesion.

Abstract: Disclosed herein, among other things, are methods and apparatus related to ablation catheters with wireless temperature sensing. The present subject matter provides an ablation catheter system including an ablation transducer and a wireless temperature sensor. The wireless temperature sensor includes at least one temperature sensing element configured to sense a temperature-dependent parameter, circuitry configured to measure the sensed parameter and compute a temperature, a transmitter configured to wirelessly transmit a signal including at least one of the sensed parameter and the computed temperature, and a power supply. A controller is provided to coordinate timing of ablation therapy and sensing of the wireless temperature sensor, in various embodiments.

Abstract: A photoacoustic catheter can include an elongate shaft and a first photoacoustic transducer. The elongate shaft can extend from a proximal region to a distal region and can include a first light guide that is in optical communication with a light source. The first photoacoustic transducer can be disposed within the distal region of the elongate shaft and can be in optical communication with the first light guide. The first photoacoustic transducer can impart acoustic pressure waves upon a calcified lesion to induce fractures. The first photoacoustic transducer can include a light-absorbing material and a thermal expansion material that can be in contact with one another.

Abstract: Disclosed herein, among other things, are methods and apparatus related to ablation catheter systems with wireless temperature sensing. The present subject matter provides an ablation catheter system including an ablation catheter configured to ablate a target zone of tissue and at least one temperature sensitive resonator coupled to the ablation catheter. The resonator is configured to wirelessly emit a signal indicative of a sensed temperature in response to an interrogation signal. The ablation catheter system also includes an external device configured to provide the interrogation signal and to receive and decode the emitted signal from the resonator. The temperature sensitive resonator is configured to be placed proximate to and in thermal conduction with the target zone of tissue and to resonate at a frequency dependent upon a temperature of the resonator when excited by the interrogation signal, in various embodiments.
