  • Pressure monitoring to control delivery of therapeutic agent
    Patent number: 8790295
    Abstract: A method for adjusting delivery of a therapeutic fluid to a patient suffering from or at risk of pulmonary arterial hypertension includes introducing the therapeutic fluid to a patient via a catheter at a predetermined rate. The catheter is positioned to deliver the fluid to the right ventricle or the pulmonary artery. The catheter a one-way valve configured to allow the fluid to flow from the catheter to the target location. The method further includes monitoring pressure of the target location by monitoring internal catheter pressure, and adjusting the rate at which the therapeutic fluid is introduced to the catheter based on the monitored pressure. The rate at which the fluid is introduced to the catheter is increased if internal catheter pressure increases, and the rate at which the fluid is introduced to the catheter is decreased if the internal catheter pressure decreases.
