Abstract

The invention provides methods for delivering bioactive agent to an eye, the methods including steps of providing a device at an implantation site within the eye, and maintaining the device at the implantation site to provide a therapeutically effective amount of the bioactive agent to the eye. The device includes a body member having a direction of extension, a longitudinal axis along the direction of extension, and a proximal end and a distal end, wherein at least a portion of the body member deviates from the direction of extension. A polymeric coated composition is provided in contact with a surface of the body member, the polymeric coated composition including a first polymer, a second polymer, and a bioactive agent. The invention also provides methods of administering a therapeutically effective amount of bioactive agent to a posterior segment of an eye.

Description

[0001] This application is a continuation of U.S. application Ser. No. 10 / 835,530, filed Apr. 29, 2004, entitled “CONTROLLED RELEASE BIOACTIVE AGENT DELIVERY DEVICE”, which claims the benefit of U.S. Provisional Application Ser. No. 60 / 467,419, filed May 2, 2003, entitled “CONTROLLED RELEASE BIOACTIVE AGENT DELIVERY DEVICE,” which applications are incorporated herein by reference in their entirety.FIELD OF THE INVENTION

[0002] The invention relates to a delivery device for controlled delivery of one or more bioactive agents to a treatment site within the body. BACKGROUND OF THE INVENTION

[0003] Many surgical interventions involve placement of a medical device into the body. While beneficial for treating a variety of medical conditions, the placement of metal or polymeric devices in the body can give rise to numerous complications. Some of these complications include increased risk of infection, initiation of a foreign body response (which can result in inflammation and / or fibrous en...
