Abstract
A micro-machined drug delivery device and method of use for the delivery of labile drugs is disclosed. A micro-machined sensing device and method of use is also disclosed. A micro-machined drug delivery and sensing device and method of use is additionally disclosed. All three devices are intended to be inserted into a patient's body. The drug delivery devices allow for the mixing of drug components prior to the release of the mixture into the patient's body where the mixture is labile. The micro-machined sensing device is suitable for monitoring the concentration of a specific chemical in a patient's body fluids when the monitoring requires a labile reagent that must be mixed prior to introduction of the body fluid into the sensing device. The micro-machined drug delivery and sensing device is especially applicable in situations where the prompt delivery of labile drugs is necessary.
