Abstract: Embodiments of the invention include devices, compositions and methods for the controlled release of therapeutic substances, such as drugs. Control over the rate of release of the therapeutic substances from the devices is achieved by the use of nanoporous membranes in which the pore size is matched to the molecular diameter of the therapeutic substances. Some embodiments of the invention achieve zero-order release by the use of membranes with a pore diameter that is more than five times the Stokes' diameter of the therapeutic substance released.

Abstract: The disclosure pertains to implantable medical devices for controlled delivery of therapeutic agents.

Abstract: The disclosure pertains to the field of treatment of patients with implantable delivery devices for long-term release of therapeutic agents. In particular, the disclosure provides devices and methods for the stabilization of the therapeutic agents inside the device for the duration of the implantation. The devices control the long-term release of the therapeutic agents by using a nanoporous membrane. The stabilization is achieved by using high-molecular weight stabilizers of a size that is larger than the diameter of the pores of the membrane, thereby preventing the release of the stabilizers.
