Abstract

Bioerodible, sustained release preparations are provided for placement into the bladder through the urethra which provide sustained release of drugs. Configurations are provided which are insertable through a catheter, such as a coiled filament, patch or a flowable gel. The device is bioeroded during or after the sustained release of the drug such that there is no blockage of the urinary tract while the device is in place within the bladder.
