NASOLACRIMAL DRAINAGE SYSTEM IMPLANTS FOR DRUG THERAPY. |
摘要 |
Implant devices, systems and methods for insertion into a punctum of a patient optionally comprises a drug core and a sheath body disposed over the drug core. The drug core includes a therapeutic agent deliverable into the eye, and the sheath defines at least one exposed surface of the drug core. The exposed surface(s) of the drug core may contact a tear or tear film fluid and release the therapeutic agent at therapeutic levels over a sustained period when the implant is implanted for use. The implant may include a retention element to retain the drug core and sheath body near the punctum, optionally comprising a shape memory alloy that can resiliently expand. An occlusive element may be attached to the retention element to at least partially occlude tear flow through the canalicular lumen. |
