  • Method for manufacturing a controlled-release device
    Patent number: 5958317
    Abstract: A method of manufacturing a controlled-release device is described. The method comprises taking a hollow tubular element which is permeable to the active substance to be released and injecting it with at least two plugs of hardenable material. These plugs form partitions which block the hollow tubular element and are spaced apart to form at least one discrete hollow chamber. The hardenable material is then hardened and an active substance is introduced into at least one of the discrete hollow chambers.
