  • Patent number: 6375978
    Abstract: This invention provides rate controlling membranes for controlled drug delivery devices that are stable over time and exhibit more predictable and consistent membrane functionality. According to another aspect, the membranes have enhanced permeability. According to the invention, the rate controlling membrane of a controlled drug delivery device is subjected to a pre-treatment annealing process wherein it is subjected to an elevated temperature for a predetermined time period and subsequently cooled to ambient conditions before incorporation into a controlled drug delivery device.
