Abstract

Disclosed herein is a shield for shielding a telemetry wand from electromagnetical interference capable of interfering with telemetry communications between the telemetry wand and an AIMD in a patient. The telemetry wand may include a first side that is configured to be placed against a patient, a second side generally opposite the first side, a lateral side between the first and second sides, a hole extending between the first and second sides, and a cable extending from the lateral side. The shield may include a shell including a wall that defines a volume and an opening in the shell. The volume may be configured to receive therein the telemetry wand such that the second and lateral sides of the telemetry wand face respective portions of the wall and the first side faces the opening in the shell.
