Abstract: A method of making an injectable or implantable active agent delivery device capable of delivering a diagnostic, therapeutic, and/or prophylactic agent to a desired targeted site having orifice(s) on the surface is disclosed herein providing unidirectional release of the agent at a controlled desirable rate. The agent may include, but is not limited to, drugs, proteins, peptides, biomarkers, bioanalytes, and/or genetic material. The technology of the invention is based on parallel processing to fabricate micro-holes on tubes employing photo-lithography and reactive ion etching techniques and also incorporates a simple molding method to form the micro-holes on flexible polymer tubes, including bio-degradable tubes. The parallel processing method of the instant invention is fast, economical and well suited for mass production. The developed device, due to its composite structure, has the ability to combine several release mechanisms, leading to zero-order release kinetics for most of the time.

Abstract: An injectable or implantable medical device having orifice(s) on the surface that release an active agent with zero-order release kinetics is described herein. The device is a hollow matrix of any size or shape, which can be made from both metal and non-metal surfaces. The device comprises of a reservoir capable of releasing at least one therapeutic, diagnostic, or prophylactic agent via the orifices to the desired anatomical site. The developed device, due to its composite structure, has the ability to combine several release mechanisms, leading to zero-order release kinetics for most of the time. The composition provides zero-order kinetics, in part, because the diffusion rate of the drug from the device is slow which enables sink conditions. Hence, no back transfer or build up of drug occurs at anytime. Polymers are not required for controlled release.
