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.
