  • Patent number: 8524259
    Abstract: Systems and methods for delivering release materials, for example drugs and other bioactive materials. Crystalline polymeric systems, referred to as CYC carriers, are associated with the release materials, through chemical bonding or through physical association. The crystallinity of the CYC carriers results from the presence of crystallizable side chains, for example long chain n-alkyl moieties, which results in relatively low and sharp melting temperatures. One class of CYC carriers, referred to as CYSC polymers, have a majority of the crystallizable side chains pendant from the polymer backbone. Another class of CYC carriers referred to as ECC polymers, have a majority of the crystallizable side chains attached to terminal units of the polymer backbone. The ECC polymers can for example be obtained by modification of PLGA polymers. The CYC carriers in another class of non-polymeric.

  • Patent number: 8499966
    Abstract: A method of administering small, bioadhesive drug tablets includes moving an end portion of a delivery member. A surface of the delivery member can be positioned to prevent movement of the drug tablet from a tablet cartridge channel to a delivery passage of a delivery device when the end portion of the delivery member is in a first stopped position. The end portion of the delivery member can be moved to a second position within the delivery passage such that the tablet cartridge channel is in communication with the delivery passage. The drug tablet can be conveyed into the delivery passage via the tablet cartridge channel. The end portion of the delivery member can be moved to a third position within the delivery passage to convey the drug tablet through an exit opening of the delivery device.
