The first leadless pacemaker, less than one-tenth the size of a conventional pacemaker, has been approved for use in Europe. It can be delivered via a catheter into the heart.

There will be elimination of the visible lump and scar at a conventional pacemaker’s implant site. Also there is removal of patient activity restrictions that may prevent the dislodgement or damage to a conventional lead.

Initial results from the first–in–man LEADLESS study showed successful implantation in 32 of 33 patients and performance comparable with traditional pacemakers with leads.
