Abstract:
1. A method for adjusting delivery of a therapeutic fluid to a patient suffering from or at risk of pulmonary arterial hypertension, the therapeutic fluid being delivered from an implanted catheter to a target region of the patient into which the catheter is implanted, wherein at least a portion of the catheter is implanted in the right ventricle or the pulmonary artery of the patient, the method comprising: introducing the therapeutic fluid to the catheter at a predetermined rate, the catheter having a delivery region implanted in the target location; monitoring pressure of the right ventricle or the pulmonary artery by monitoring internal catheter pressure; and adjusting the rate at which the therapeutic fluid is introduced to the catheter based on the monitored pressure, wherein the rate at which the therapeutic fluid is introduced to the catheter is increased if the internal catheter pressure increases, and wherein the rate at which the therapeutic fluid is introduced to the catheter is decreased if the internal catheter pressure decreases.
