1. An implantable device for drug delivery comprising:
- a biologically inert hollow body defining at least one void;
said void containing at least one drug;
said hollow body having a generally oval shape;
said oval shaped body being curved such that it substantially conforms to the spherical curvature of at least a portion of a recipient'"'"'s eye,said oval shape being optimized to minimize physical stress on the retina;
said inert body further comprising at least one mounting aperture suitable for attaching said inert body to a retina with a tack andsaid inert body further comprising a strain relief tab which is thinner than the rest of said inert body, defined by a strain relief slot partially around said mounting aperture.

Abstract
The invention is directed to an implantable device to enable delivery of drugs to the retina. The device minimizes stress to the retina by virtue of its softness and smooth shape that conform to the retina. Drugs are delivered by osmosis or by the device dissolving. It may be connected to an externally mounted pump and drug reservoir that control the amount of drug. It contains one or more holes that are positioned to deliver drugs to the desired location. Drugs may stimulate the retina to enable vision in blind patients. Drugs may be injected directly inside the eye by a trans-scleral pump and valve drug delivery device.
