Slightly bigger than a matchstick, lighter than a two-rupee coin and wireless. Patients may get this pacemaker by the middle of this year. It will have the same efficiency as that of a conventional device, but is priced substantially higher than the existing ones.
But the world's smallest pacemaker will use an improved technology that will benefit cardiac patients in the long run and is bound to edge out the existing pacemakers that have a clumsy wiring, feel experts.
Recommended for people whose hearts are beating too slowly or irregularly , a pacemaker stimulates the heart muscle with precisely-timed discharges of electricity that cause the heart to beat in a manner similar to the natural heart rhythm.
The Micra Transcatheter Pacing System (TPS) -which could hit the market in June -is a miniaturized, self-contained device that is one-tenth the size of conventional pacemakers, yet delivers the most advanced pacing technology available to patients. "Besides being small, the implant has no wires and is one-tenth the size of a conventional pacemaker. The wires or `leads' in existing devices often turn cumbersome since they can't be taken out with the pacemaker and forms a clump near the heart. But with TPS, successive implants will become easier," said Atul Mathur, director of interventional Cardiology , Fortis Escorts Heart Institute, New Delhi.
The new device will be the size of a vitamin capsule and can be implanted through a minimally invasive procedure. It will be delivered straight to the heart through a catheter via the femoral vein. This cuts out the need for incision and the pocket near the heart where a conventional pacemaker is lodged.
"Since there is no incision, the chances of complications arising from it are also eliminated. More importantly , patients can undergo full-body MRI scans with the implant, which are not permitted in case of the conventional devices," Mathur said.
But the cost may be a deterring factor. While existing pacemakers cost up to Rs 1.5 lakh, the TPS could be priced at Rs 2.5 lakh. But the price could come down over the next two years, felt experts.
"The size is an advantage, apart from the fact that since the technology will be advanced, it will pack in more features. In terms of efficiency, the existing pacemakers are good enough. But with time, smaller implants should have all the features of a multi-chambered pacemaker," said Debashish Saha, consult at AMRI Hospital, Salt Lake.
