In most heart device implants, an incision is made just below the collarbone. Then, leads are inserted and attached to the heart tested to make sure they are working properly. The leads are then connected to the device and everything is placed under the skin prior to closing up the incision and finishing the procedure.

Leadless pacemaker implants start with the insertion of a straw-like catheter system into a vein, typically near the upper thigh area of the leg. The catheter system moves the leadless pacemaker into the right ventricle of the heart where the device is placed against the heart wall and secured with flexible tines. The leadless pacemaker is tested to ensure it is working properly. The catheter system is then removed.
