Abstract
An occlusion penetrating system and method including a probe with an impact member, an actuator for vibrating the impact member, and a sensor configured to measure the impact force of the impact member. A catheter delivers the impact member within a tube (e.g., vasculature), a power supply is connected to the actuator for energizing the actuator, and a processing subsystem is responsive to the measured impact force of the impact member and is configured to ascertain whether the impact member is impacting the tube or an occlusion (e.g., plaque) in the tube and to automatically deenergize the actuator when the measured impact force indicates the impact member is impacting the tube.
Claims26
An occlusion penetrating system comprising:
- a probe including:
- an impact member,
- an actuator for vibrating the impact member, and
- a sensor configured to measure the impact force of the impact member;
- a catheter for delivering the impact member within a tube;
- a power supply connected to the actuator for energizing the actuator;
- and
- a processing subsystem responsive to the measured impact force of the impact member and configured to ascertain whether the impact member is impacting the tube or an occlusion in the tube and to automatically deenergize the actuator when the measured impact force indicates the impact member is impacting the tube.
An occlusion penetrating method comprising:
- inserting a catheter about an impact member into a tube;
- driving the impact member out of the catheter;
- vibrating the impact member;
- measuring an impact force of the impact member;
- determining whether the impact member is impacting the tube or an occlusion in the tube;
- if the impact member is impacting the tube, stopping the impact member from impacting the tube;
- and
- if the impact member is impacting the occlusion, vibrating the impact member until the occlusion reaches structural failure.
