Remote control drug delivery device
First Claim
1. A drug delivery system comprising:
- a housing;
a drug storage chamber located within the housing and having at least one exit port, the drug storage chamber for holding at least one predetermined dose of a predetermined drug;
a drug delivery chamber disposed within the drug storage chamber;
a gas pressurized chamber located within the housing for holding a gas under pressure;
a valve connecting the gas pressurized chamber with the drug delivery chamber, the valve having an open position and a normally closed position, wherein in the open position, the gas is delivered through the valve to the drug delivery chamber;
a remotely activated control circuit electrically connected to the valve for receiving a remotely generated valve open signal and generating an electrical valve open signal therefrom, and providing the electrical valve open signal to the valve; and
a signaling device spaced from the control circuit for transmitting the remotely generated valve open signal to the control circuit, wherein upon receipt of the electrical valve open signal, the valve opens such that the gas in the gas pressurized chamber is released into the drug delivery chamber, thereby forcing a predetermined dose of the drug into the at least one exit port and out of the housing.

Abstract
A remotely controlled drug delivery device administers a dose of a drug, agent or microbicide using a gas pressure delivery system. The device stores multiple doses of the drug or agent. A toroid shaped housing includes three chambers, a gas chamber containing a pressurized gas, a drug storage chamber containing the drug or agent, and an expandable chamber for delivering the drug from the drug storage. The device includes an electronic controller for opening a valve connecting the gas chamber to the expandable chamber for a predetermined period of time in order to deliver a predetermined dose of the drug. The controller communicates with a remote control device via radio frequency. The remote control device sends a signal to the controller, which causes a dose to be delivered. The controller returns a signal to the remote control device indicating that the dose has been delivered and a signal indicating when the device needs to be removed for maintenance. The device may be used in any body cavity to deliver any desired type of drug.
