Abstract
A system and method for physiological monitoring and regulation of a drug infusion device. The system includes an internal compact unit that is implantable in a patient having a pulmonary disorder, the internal unit encasing a power supply, a fluid reservoir, a motor pump, a digital control unit, and a radio frequency transmitter. An infusion catheter is connected to the fluid reservoir and motor pump for automatically infusing a drug into a right ventricle of the patient during a diastole phase of a cardiac cycle. The system includes an external unit for monitoring and storing a plurality of physiological parameters of the patient and for making adjustments to a drug infusion rate.
Claims25
A system for physiological monitoring and regulation of a drug infusion device, comprising:
- an internal compact unit that is implantable in a patient, the internal compact unit comprising a radio frequency transmitter, a fluid reservoir, and a motor pump;
- an infusion catheter comprising a radially dense helical structure and a supporting frame, wherein the infusion catheter is connected to the fluid reservoir and motor pump for infusing a drug into the patient;
- and
- an external unit in communication with the radio frequency transmitter that monitors one or more physiological parameters of the patient for making adjustments to a drug infusion rate.
A system for physiological monitoring and regulation of a drug infusion device, comprising:
- an internal compact unit that is implantable in a patient, the internal compact unit comprising a radio frequency transmitter, a fluid reservoir, and a motor pump;
- an infusion catheter connected to the fluid reservoir and motor pump for infusing a drug into the patient, wherein the infusion catheter comprises a hemodynamic pressure sensor located at the tip of the infusion catheter that measures relative change in pressure over time;
- and
- an external unit in communication with the radio frequency transmitter that controls adjustments to a drug infusion rate based on the relative change in pressure.
A drug infusion device for infusing a drug into a patient, comprising:
- a catheter for infusing the drug into the patient, the catheter comprising a radially dense helical structure and a supporting frame;
- a fluid reservoir for storing the drug;
- and
- a pressure sensor located at the tip of the catheter that measures relative change in pressure over time,
- wherein the drug is delivered to the patient through the catheter based on the relative change in pressure over time.
