Antenna Care
Antennas are used to transfer radiofrequency (RF) energy from the Mark IV transmitter through the skin to the implanted receivers and electrodes. The system will not work unless the antennas are affixed to the patient's skin, directly over the implanted receivers. Proper care and gentle handling will make them last longer, but they will eventually wear out.

It is recommended that patients always have a spare pair of antennas available. |
Antennas can be held in place using hypoallergenic adhesive tape. A suggested method for taping is shown to the right. It is recommended that tape location be changed frequently to avoid skin irritation.
A thin layer of polypropylene or similar material may help alleviate skin irritation due to perspiration when placed directly beneath the antenna. Amplitude settings may need to be adjusted accordingly to maintain adequate ventilation.
Alternatively, elastic netting that conforms to body shape, abdominal binders, elastic bandages, or gas permeable dressings such as Tegaderm® can be used.
Antennas that are discolored, damaged, or perform intermittently should be discarded as they cannot be repaired. The following suggestions should help maximize the useful life of an antenna:
• Antenna wires should be run in a straight line or gently looped between the receiver and the transmitter. Do not bend or kink the wire.
• The point of greatest stress is where the antenna wire meets the metal connector. Keep this area free from bending or pulling.
• Wash antennas periodically with warm soap and water, but do not soak. Rinse and allow to dry thoroughly before use.
• Do not allow the metal connector to become wet.
• Adhesive buildup from tape or other dressings can be removed with a cloth dampened in rubbing alcohol.
• Accumulation of dirt or other debris in the antenna connector or antenna socket on the Mark IV may affect operation of the system.
Service Plans
For patients whose Mark IV transmitters are out of warranty, optional service agreements are available to defray the costs of repairs and necessary supplies. Patients should expect to receive information regarding these plans in advance of warranty expiration date of their transmitter. Anyone interested in these plans should contact the ABD technical services department for additional information.
Insurance Policies
Due to the costs involved in replacing an external transmitter, ABD highly recommends that the patient's external transmitter be covered against loss under an insurance policy. This can be done either as a separate policy or as a rider to an existing homeowner's or renter's policy. Please contact the ABD accounting department if you require an invoice or other documentation for this purpose.
