  • Patent number: 7875290
    Abstract: A drug delivery device such as an oral dosage form (ODF) with a toxic or potent core encapsulated by a non-toxic region. The non-toxic region may be a region including multiple layers, coatings, shells, and combinations thereof, which provides protection to and isolation from the toxic or potent core. The drug in the toxic or potent core is incorporated into the dosage form via, for example, three-dimensional printing, as a solution, solubilization or suspension of solid particles in liquid, rather than by the more conventional handling and compressing of dry powder. This minimizes the likelihood of creating airborne particles of the toxic drug during manufacturing, hence controlling and minimizing the exposure of manufacturing personnel to the hazardous substance. Wet dispensing of the toxic or potent drug further provides greater bioavailability of the drug to the patient.

  • Patent number: 7445441
    Abstract: The invention includes a three-dimensional printing (3DP) machine that has at least one ultraviolet (UV) light source directed at powder or slurry being processed by the 3DP machine and/or directed at any of various surfaces or machine components, in a manner suitable to kill or damage microorganisms to a desired extent. The UV light sources may be either stationary or movable, and may be either pulsed or substantially continuous, and may operate in any desired sequence and timing with respect to other operations performed by the machine. The invention may include ultraviolet illumination in such a way as to interact with powder to sterilize or disinfect powder either while the powder is stationary or, alternatively, as powder is being moved from one place to another within the 3DP machine, or both. The invention also includes methods of performing three-dimensional printing using such illumination.

  • Publication number: 20040243481
    Abstract: The rapid design and manufacture of biomedical devices such as implants, oral dosage pills and implantable pharmaceuticals employs electronic data and modeling transmissions via a computer network. Patient information and patient-specific radiological data is captured and transmitted via a computer network to a design and/or manufacturing site. A multi-dimensional digital model is created based on the radiological data and patient information. Communications interchanges between a clinical/diagnostic site and a design/manufacturing site permit modification of the digital model until approved. The approved digital model is converted into machine instructions to construct the biomedical device. Alternatively, the digital model is employed in a best fit selection of a biomedical device from a pre-existing set of biomedical devices or machine-instructions. Transmittal of data over computer networks is further directed to the use of a Website to perform various client-interaction and follow-up tasks.

  • Publication number: 20040091516
    Abstract: The invention includes dispensing a suspension containing solid particles for use in manufacturing a dosage form or other biomedical article by 3DP. The suspension contains solid particles suspended in a liquid. The solid particles may be one or more Active Pharmaceutical Ingredients. The solid particles may be particles of material that are insoluble in the liquid, or they may be particles of a substance that have already dissolved in the liquid up to the saturation level and are present in a concentration beyond what can be dissolved. In addition to solid particles, the liquid may also contain other substances dissolved in it, either substances containing Active Pharmaceutical Ingredients (API) or substances without API. One aspect of the invention includes prevention of agglomeration by adding one or more of several categories of additives to the suspending liquid.
