Implantable drug delivery device
First Claim
1. An implantable device for drug delivery comprising:
- a biodegradable body;
said body having a generally oval shape suitable to be placed adjacent to the plane of a retina, said oval shaped body being curved such that it substantially conforms to the spherical curvature of at least portion of a recipient'"'"'s eye.

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.
