  • Publication number: 20240399054
    Abstract: An implantable medical device configured to selectively permit access to a medicament reservoir or fluid pathway by way of at least one contactless key, including an implantable medical device having a medicament reservoir fluidly coupled to an access port via a first conduit and a second conduit via an access valve, and at least one contactless key configured to impart a magnetic field upon a portion of the implantable medical pump to manipulate the access valve among a first position fluidly coupling the medicament reservoir to the access port via the first conduit, and a second position fluidly coupling the medicament reservoir to the access port via the second conduit, and a third position isolating the medicament reservoir from the access port.

  • Patent number: 12083316
    Abstract: An implantable medical device configured to selectively permit access to a medicament reservoir or fluid pathway by way of at least one contactless key, including an implantable medical device having a medicament reservoir fluidly coupled to an access port via a first conduit and a second conduct via an access valve, and at least one contactless key configured to impart a magnetic field upon a portion of the implantable medical pump to manipulate the access valve between a first position fluidly coupling the medicament reservoir to the access port via the first conduit, and a second position fluidly coupling the medicament reservoir to the access port via the second conduit, and a third position isolating the medicament reservoir from the access port.

  • 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.
