Telemetry apparatus for communications with an active device implanted in a patient's thoracic region
First Claim
1. Apparatus for telemetry communication with an active device implanted in a thoracic area of a patient, the active device including one of a pacemaker, a resynchronization, a defibrillation, a cardioversion device, and a diagnostic device, said apparatus being external to the implanted active device and comprising:
- a cloth in the form of a vest covering at least one part of the patient'"'"'s anatomy and having a frontal outer surface;
a wave collector transmitting and receiving signals to and from said implanted device through an inductive channel;
a first wire connecting said wave collector to an electronic circuit package for transmission, reception and processing of the signals;
a peaking coil associated with the wave collector, the peaking coil being embedded within the cloth and sensing noise components;
a second wire connecting said peaking coil to the electrical circuit for transmission of the noise components;
a support structure receivably supporting the wave collector; and
adjustable means for fixing said support structure at a chosen location on the frontal outer surface of said cloth, said support structure when fixed at said chosen location placing the wave collector within a magnetic coupling region between said wave collector and said implanted device,wherein, after an initial placement of said support structure on the frontal outer surface of said cloth, at said chosen location, the wave collector is placed repeatedly withinthe magnetic coupling region every time the patient wears the cloth, and wherein the electrical circuit subtracts the noise components from the signals.

Abstract
Apparatus for telemetry equipment for communication with an active device implanted in the thoracic area of a patient This equipment includes a wave collector (16) essentially sensitive to a magnetic field so as to allow an exchange of signals through magnetic coupling (i.e., an inductive channel) with the implanted device (14). The wave collector is connected to an electronic circuit package (24) for transmission/reception and signal processing of acquired data and programming. The apparatus further comprises a cloth (10) in the form of a vest to be worn by and able to cover at least one part of the patient'"'"'s anatomy, a support structure (18) for receiving and supporting the wave collector, and adjustable members able to fix the support structure at a chosen location of the cloth, for example, by means of hooking tapes (20) disposed on the support (18) and cooperating surface material on the cloth. Thus, after initial positioning of the wave collector in front of the area where the device is implanted, placement and maintaining of the wave collector will be fixed to that location each time the patient puts the cloth on.
