  • Patent number: 5137669
    Abstract: A bioerodible pellet capable of administering an even and continuous dose of a peptide over a period of up to a year, when subcutaneously implanted, is provided. The bioerodible implant is a partially-fused pellet, which pellet has a peptide drug homogeneously-bound in a matrix of a melted and recrystallized, nonpolymer carrier. Preferably, the nonpolymer carrier is a steroid and in particular is cholesterol or a cholesterol derivative. In one embodiment, the peptide drug is growth hormone-releasing hormone. A method for making the bioerodible pellet also is provided.
    Type: Grant

  • Patent number: 4994028
    Abstract: A device for subcutaneous implantation of a plurality of solid, elongated medicinal pellets. The device includes a needle-like, hollow cannula within a barrel. The hub has a manually engageable knob thereon so that the hub and cannula may be easily moved with respect to the barrel with the thumb of one hand during the implantation process. An obturator extends from the rear of the barrel into the proximal end of the cannula. The obturator is composed of two or more sections which allow it to telescope during operation.

  • Patent number: 4877774
    Abstract: Crystalline complexes of steroid hormones with gamma-cyclodextrin are prepared by mixing the components together. Tablets can be formed from the complexes, which can be administered by contact with the mucosa to provide effective transfer of the hormones into the systemic circulation, gradually eliminating the hormones therefrom.

  • Patent number: 4661103
    Abstract: An improved magazine type implant injector having a slotted barrel element slidably mounting an integral magazine element and cannula. The barrel element mounts an obturator which projects into the magazine element to serially advance elongated implants to the cannula, each implant advancing a previously engaged implant through the distal end of the cannula for implantation.
