VASODILATOR DELIVERY REGULATED BY BLOOD PRESSURE OR BLOOD FLOW
First Claim
Patent Images
1. A fluid delivery system comprising:
- a fluid delivery device configured to deliver a vasodilator;
a sensor configured to sense at least one of blood pressure or blood flow in one of a ventricle or an atria of a heart, a pulmonary artery, and a renal vessel; and
a processor configured to trigger a therapeutic action when the sensed at least one of blood pressure or blood flow traverses a threshold.

Abstract
The effectiveness of a vasodilator delivered to a patient and/or the operation of the fluid delivery device from which the vasodilator is delivered are evaluated based on feedback from one or more sensors implanted within the patient. A fluid delivery system includes a fluid delivery device, a sensor, and a processor. The fluid delivery device is configured to deliver a vasodilator. The sensor is configured to sense at least one of blood pressure or blood flow in one of a ventricle or an atria of a heart, a pulmonary artery, and a renal vessel. The processor is configured to trigger a therapeutic action when the sensed at least one of blood pressure or blood flow traverses the threshold.
