Abstract
The devices, systems, and methods disclosed herein may be directed to a delivery system including a therapeutic member configured for endoluminal placement via the delivery system into the esophagus of the patient, wherein the therapeutic member comprises a treatment portion comprising a film for controlled release of a chemotherapeutic agent. The film may comprise a control region, a therapeutic region, and a substantially impermeable base region. The film is configured to release the chemotherapeutic agent in a direction away from the substantially impermeable base region. The delivery system is configured to enable a treatment provider to position the treatment portion of the therapeutic member proximate to a treatment site associated with the esophagus of the patient, and the therapeutic member is configured to administer a therapeutically effective dose to the treatment site for a sustained period following endoluminal placement of the therapeutic member.
