Integrated intra-dermal delivery, diagnostic and communication system
First Claim
1. An intra-dermal delivery system comprising:
- a plurality of drug delivery devices that are arranged in an array, the plurality of drug delivery devices for intra-dermally delivering at least one drug below a stratum corneum, the at least one drug being stored in at least one storage cell within each of the plurality of drug delivery devices, each drug delivery device of the plurality of drug delivery devices having a lancet and an actuator causing selective movement of a respective drug delivery device to deliver the at least one drug contained in the at least one storage cell of the respective drug delivery device below the stratum corneum;
a programmable controller in communication with the plurality of drug delivery devices for controlling the actuation of the actuators of the plurality of drug delivery devices; and
a biofeedback device that is in communication with the programmable controller and includes at least one biosensor that is configured to measure at least one bio-property of a patient,wherein the programmable controller is programmed based on patient information to deliver the at least one drug at a prescribed time or based on a signal received from the biofeedback device;
wherein the actuator of each drug delivery device of the plurality of drug delivery devices comprises a first actuating element and a second actuating element, and wherein each at least one storage cell includes the first actuating element associated therewith; and
the lancet of each drug delivery device of the plurality of drug delivery devices has a delivery conduit defined by an entrance and an exit defined at a sharp distal end of the lancet, each lancet having the second actuating element associated therewith;
wherein at least one of the first and second actuating elements is energized by a source of power to cause the first and second actuating elements to move together resulting in the lancet being driven toward and through the at least one storage cell so as to cause the one respective drug stored in the at least one storage cell to flow into the entrance, through the lancet to the exit for releasing the one respective drug below the stratum corneum.

Abstract
In one embodiment, an IDDC system utilizes an intelligent therapeutic agent delivery system comprised of one, but more likely an array of “cells” containing therapeutic agent(s) and/or diagnostic agents(s); an integrated bio-sensing system designed to sample and analyze biological materials using multiple sensors that include both hardware and software components. The software component involves biomedical signal processing to analyze complex liquid mixtures and a microcontroller(s) acts as interface to the biosensors, to the therapeutic delivery elements, and to a communications system(s) for the purpose of controlling the amount of therapeutic agent to deliver and also to provide information in a useful form to interested parties on the progress of therapy and compliance thereto. The synergistic effect of combining the above describe elements is expected to dramatically improve patient compliance with prescribed therapy, quality and timeliness of care provided by physicians, and at the same time reduce the cost of providing effective healthcare to IDDC system users, thereby improving profitability for Managed Care organizations and pharmaceutical companies utilizing the system.
