  • Publication number: 20210316038
    Abstract: In various embodiments, the present invention is directed to a drug-loaded amino acid based poly(ester urea) pouch or pocket sized to receive implanted devices that produces localized drug delivery. In some embodiments, the present invention is directed to an antibiotic-loaded L-Valine poly(ester urea) pouch or pocket that provides localized antibiotic delivery for CIEDs or other implanted devices. In one or more embodiments, the amount and rate of antibiotic release are dependent upon the thickness and loading concentration of the film. This dependence of release on thickness and loading concentration gives a handle to fabricate PEU-A pouches or pockets with any desired release profile that can locally deliver the therapeutically relevant amount of antibiotic.

  • Publication number: 20200289178
    Abstract: Self-aligning plating systems and methods are disclosed. The self-aligning plating system may include an interbody spacer, a medical device plate, and an insertion member. The interbody spacer may be inserted between a top vertebra and a bottom vertebra of a patient's spinal column. A medical device plate may slide along an insertion member in operable connectivity with the interbody spacer so that the medical device plate comes into contact with and can be secured to the patient's anatomy.

  • Publication number: 20170172706
    Abstract: A post for a dental crown is disclosed having improved structural features—including increased post strength and reduced likelihood of root fracture. In one embodiment, the post includes a quadrangle (4-way) split shank for increased compliance and root stress reduction while providing very high mechanical grip strength and pull-out resistance. In another embodiment, a shortened threaded section and a thread-free shank tip minimize the possibility of root fracture while still providing high grip strength and pull-out resistance. Embodiments also include a radiused transition from a primary thread to a secondary thread portion of the shank for stress reduction; and axial grooves, cross-axis through holes and other shape features of the post head for increased crown retention strength.
