NEUROSTIMULATION PROGRAMMERS WITH IMPROVED RF ANTENNA RADIATION PATTERNS

摘要

To provide for an improvement in the communication between an external handheld programmer and an implantable pulse generator (IPG) implanted within a patient or an external pulse generator attached to the patient, an antenna of the programmer is positioned relative to the ground plane of the programmer such that when a person handholds the programmer in its predetermined intended orientation a radiation pattern produced by the antenna has substantially maximum RF radiation generally directed toward the patient, regardless whether the person that handholds the programmer is the patient or another person located near the patient.
