Abstract
An implantable medical pump system configured to selectively permit access to a medicament reservoir by way of at least one contactless key, including an implantable medical pump having an medicament reservoir fluidly couple to an access port via a conduit including 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 closed position isolating the medicament reservoir from the access port, and an open position fluidly coupling the medicament reservoir to the access port.
