Abstract:
The invention provides a drug delivery device for one or more drugs. The device has a drug core which is surrounded by an internal and external sheath. The external sheath has a first cap that is permeable to at least one drug in the core. The first cap may comprise polyvinyl alcohol (PVA), and the PVA may be heat cured. In certain aspects, there are one or more additional caps on the ends of the sheaths formed from one or more polymers. In certain aspects, one or more portions of the drug delivery device are substantially impermeable to one or more drugs in the drug core. In certain aspects, the drug elutes through the first cap into a biological environment. The invention further provides methods for manufacturing the drug delivery device.
Abstract:
Disclosed herein is an injector device including an inserter element, a head element, an implant and a set of detachable protector elements for secured device handling. The device comprises a stop that controls the penetration depth of the device during injection. The device may comprise a removable catch that prevents the implant from exiting the device due to the advancement of its inserter element. The device may comprise a disengageable block that prevents the implant from exiting the device from its head element. The device may be configured for intraocular drug delivery.
