  • Systems and methods to facilitate the delivery of drugs
    Patent number: 6935336
    Abstract: A method for administering a drug to a patient comprises coupling a valve system to the patient's airway. The valve system is configured to prevent or impede respiratory gases from flowing into the lungs for at least some time such that the intrathoracic pressure is less than atmospheric pressure. A drug is introduced into the patient, and the intrathoracic pressure is lowered using the valve system to cause blood to flow into the thorax and thereby increasing vital organ perfusion to enhance the circulation of the drug.
    Type: Grant
    Filed: August 17, 2004
    Date of Patent: August 30, 2005
    Assignee: Advanced Circulatory Systems, Inc.

  • Stimulatory device and methods to electrically stimulate the phrenic nerve
    Patent number: 6587726
    Abstract: The invention provides exemplary devices and methods electrically stimulating the phrenic nerve. In one embodiment, electrodes are placed posterior and anterior in the region of the cervical vertebrae. Electrical current having a multi-phasic waveform is periodically applied to the electrodes to stimulate the phrenic nerve, thereby causing the diaphragm to contract.

  • Automatic variable positive expiratory pressure valve and methods
    Patent number: 6425393
    Abstract: The invention provides exemplary methods and valves used to alter a person's breathing. In one method, an exit valve is interfaced with a person's airway. The exit valve is configured such that respiratory gases are prevented from exiting the person's lungs when the exit valve is closed and are permitted to exit the person's lungs when the exit valve is opened. The exit valve is configured to open when a valve actuating pressure is met or exceeded. In a further step, the valve actuating pressure is varied over time.
