1. A drug delivery device, comprising:
- a stand-alone implantable body having a homogenous cross-section at all points along the implantable body, the implantable body further having two or more segments, each segment having first and second terminal ends that are each coupled to a terminal end of another segment, each segment having no membrane and having a drug-permeable polymeric substance comprising ethylene-vinyl acetate copolymer, and wherein at least one segment comprises a homogenous mixture of the drug-permeable polymeric substance and a drug such that the at least one segment is configured to release the drug at a substantially zero-order rate.

Abstract
The invention relates to an drug delivery device and a method for delivering multiple drugs over a prolonged period of time. The drug delivery device has two or more unitary segments comprising a drug-permeable polymeric substance, wherein at least one of the segments further comprises a pharmaceutically active agent. The invention also relates to a method for the treatment of a benign ovarian secretory disorder in a female mammal, a method of contraception, and a method of relieving the symptoms associated with menopausal, perimenopausal and post-menopausal periods in a woman.
