IMPROVED PROCESS FOR THE PRODUCTION OF SUSTAINED RELEASE DRUG DELIVERY DEVICES

摘要

Disclosed is an improved sustained release drug delivers device and method of producing such device. The device comprises a drug core in an impermeable cup or impermeable coating layer that is adhered to an uncured suture tab and covered with a permeable polmer coating layer that is similar to the makeup of the suture tab. The permeable polmer coating layer that covers the device, covering the impermeable coating layer and at least a portion of the drug core, is cured (after drying) along witht he uncured suture tab. The "cocuring" or one step curing process forms a very strong bond between the outer coating layer to the suture tab preventing leaks.
