  • Patent number: 8911426
    Abstract: An implantable drug delivery device that uses multiple reservoir elements to contain and release doses of active pharmaceutical ingredients. The device includes a first shell element, which has a first enclosed cavity volume and forms a low-permeability barrier. The first shell element is configured to absorb light irradiation from a laser source, the laser irradiation causing a breach in the first shell element. A first active pharmaceutical ingredient is contained in the first enclosed cavity volume and is released when the first shell element is breached. The device also includes a second shell element, which has a second enclosed cavity volume and also forms a low-permeability barrier. A second active pharmaceutical ingredient is contained in the second enclosed cavity volume. The device also includes an envelope element containing the first and second shell elements.

  • Patent number: 8597680
    Abstract: Methods and systems are provided for making a drug microtablet. The method includes loading a lyophilization capillary channel with a liquid drug solution; lyophilizing the liquid drug solution in the lyophilization capillary channel to produce a lyophilized drug formulation; compressing the lyophilized drug formulation in the lyophilization capillary channel, or in a compression capillary channel, to form a microtablet; and ejecting the microtablet from the lyophilization capillary channel or compression capillary channel. The methods and systems may provide drug microtablets having improved content uniformity and reduced weight variability.
