  • Publication number: 20220133992
    Abstract: A drug delivery port including a port housing having an inner sidewall defining a fill port cavity and a fill port washer in direct contact with a perimeter edge of the inner sidewall of the port housing such that an intersection between the washer and the perimeter edge define a plurality of filter channels having a cross-sectional flow area of about 0.001 mm2 to about 0.5 mm2 that lie within the fluid pathway of the delivery port. The delivery port also includes a port cover coupled and a pierceable septum compressed between the fill port washer and the port cover configured to allow a needle to pierce through the septum to deliver an injectable fluid to the fill port cavity.

  • Publication number: 20170181866
    Abstract: A segmented disc nucleus replacement prosthesis and system for its implantation wherein the segments are made of a compliant, homogeneous material throughout. The prosthesis comprises a plurality of modular segments that mate together in a rail-and-slot arrangement. The rails and slots are configured to interlock and hold together under load despite being formed of compliant materials. In one embodiment, insertion tools and stabilizers are utilized for manipulation of the modular segments, the insertion tools and stabilizers being designed to accommodate for handling the compliant modular segments.
