  • Patent number: 11969353
    Abstract: The present disclosure relates to prosthesis systems having trays and liners having an asymmetrical locking mechanism to bias the strength of the liner to resist loading forces and associated methods. The tray has a lateral groove disposed in an inner surface of a lateral circumferential portion of the tray and a medial groove disposed in an inner surface of a medial circumferential portion of the tray. The liner has an upper segment and a lower segment. The liner has a locking portion for lockingly engaging the tray that includes the lower segment. The locking portion has a lateral toe positioned generally diametrically opposite a plurality of resiliently deformable medial fingers defined therein. The liner and the tray are engageable in a lateral-to-medial direction so that the plurality of medial fingers can resiliently deform to engage the medial groove subsequent to engagement of the lateral toe within the lateral groove.

  • Patent number: 8719043
    Abstract: A method is disclosed to verify and identify pharmaceutical products through their product signatures in order to combat counterfeiting and reduce dispensing errors, using methods such as near infrared spectroscopy. Furthermore, in order actively evade pharmaceutical product counterfeiting, a method is disclosed where an amount of one or more of the inactive ingredients is varied over time; the variation provides a different product signature, but falling within a level deemed permissible by a regulatory body.

  • Patent number: 6319683
    Abstract: A method and composition for quenching formaldehyde fixation of cell and tissue specimens. The composition includes a formaldehyde-reactive agent. The formaldehyde-reactive agent reacts with the formaldehyde to quench the fixation of the cell or tissue specimen. The method involves contacting a formaldehyde fixative solution with the composition.

  • Patent number: 5766623
    Abstract: Active agents comprising coated pellets which self seal if they are damaged are described. More specifically, an active agent, or bead coated with an active agent, is coated with a rate-release controlling polymer and a hydrophilic gel-forming material which forms a gel upon hydration. If the bead is compressed into a solid compact which damages the polymer coating, the hydrophilic substance gels upon exposure to an aqueous environment. The gel provides sufficient sealing of the damaged area in the polymer so that a useful control of drug release is retained in spite of the damage to the polymer. The pellets of the invention exhibit improved flow and compactability. The compacts can be formulated to disintegrate in the gastrointestinal tract, and also may result in either controlled release or immediate release of the active agent.
