Abstract
A system for determining a pulse wave velocity comprises a body lumen insertable device with an actuator for providing a pulse in the vicinity of a vessel wall and a sensor for sensing arrival of the pulse. A pulse wave velocity is obtained from the time difference between actuation of the actuator and sensing of the pulse. This system is used to create an artificial pulse which is transmitted along a vessel by a known distance before detection by a sensor.
Claims18
A system for determining a pulse wave velocity of a pulse traveling along a wall of a vessel or organ, or a characteristic of the wall of the vessel or organ based on the pulse wave velocity, the system comprising:
- a body-implantable device which comprises:
- a cuff for implanting around the vessel or organ;
- an actuator for providing, through actuation of the actuator, a pulse in the vicinity of the vessel or organ wall at a first location along the vessel or organ;
- and
- a sensor for sensing the pulse at a second location along the vessel or organ, the second location being different from the first location;
- and
- a controller for:
- controlling the actuator and analyzing the sensed pulse;
- and
- determining, from a time difference between providing the pulse and sensing of the pulse, the pulse wave velocity or the characteristic of the vessel or organ wall based on the pulse wave velocity.
