APPARATUS AND METHODS FOR REPETITIVE MICROJET DRUG DELIVERY.

摘要

An active, transdermal delivery (100) system includes a support structure (128) and a fluid reservoir (102) within the support structure configured to contain a fluid (108) to be delivered transdermally. There is also at least one exit orifice (104) defined in the support structure that is in communication with the fluid reservoir. The orifice has a diameter of between about 1 micrometer and 500 micrometers. Furthermore, a repeatable activation means is disposed within the support structure and is in cooperation with the exit orifice for ejection of fluid in response to an activation signal.
