APT EP has developed a proprietary catheter shaft specific to APT EP Map-iT catheters that provides optimal torque, pushability and curve retention. The APT EP Map-iT catheter design and materials selection melds the inner and outer layers together, locking the wire braid between them and creating a composite structure that delivers flexibility, torquability and pushability performance that lasts throughout the entire procedure.

Electrode-Shaft Interface Technology
The APT EP Map-iT catheter electrode shaft interface is smooth by design. Raising the shaft material flush against the electrode edges makes a very smooth electrode-to- shaft transition. This results in no joints or glue on the shaft allowing the electrodes to make direct contact with the tissue to provide signals for the physician.
In the image above the arrows show the bumps created by the glue used to cover the sharp edges of the electrodes. Those bumps may prevent the electrodes from coming in contact with the myocardium resulting in reduced signal quality.
Deflection Handle Technology
APT EP catheters feature an excellent handle technology resulting in an easy and smooth push-pull deflection, for a less tiring procedure - potentially eliminating “numb thumb” syndrome.
