Super Plastic: A new hope for heart patients

New Delhi
In what may turn out to be a major breakthrough for millions of congestive heart failure patients, a medical device made of' Super Plastic' invented by NASA engineers for space applications has been used in India for the first time to deal with the chronic condition.

The device, which is said to be the thinnest lead (a special wire) in the world that helps deliver energy from the pacemakers or cardiac resynchronisation therapy (CRT) devices to heart muscles to maintain its normal functioning, has been successfully implanted in two heart patients in a city-based hospital recently.

Christened as Attain Ability, it has been developed by US-based medical technology giant Medtronic Inc using the insulation material invented by NASA chemical engineer Dr Robert G Bryant at the agency's Langley Research Centre.

The' Super Plastic', a special multi-purpose, highly flexible and recyclable thermoplastic material, is used for high-speed aero research programmes as it can bear extreme hot and cold temperatures. The material is suitable for medical use, including implantable devices.

" This is the first time that a NASA spin-off technology is being used in an implantable device of this kind," Dr Balbir Singh, Sr consultant Electrophysiotherapy and Interventional Cardiology, Indraprastha Apollo Hospital, said.

" Thin leads can be very helpful for those patients who need multiple leads to be implanted. Such thin leads can be inserted through puncture much lesser in diameter, thus increasing the efficiency of the surgery," Dr Harshwardhan, Head Cardiology in the Ram Manohar Lohia Hospital, said.

The new device has undergone clinical trials with 96.4 per cent success rate and has recently been approved by the US Food and Drug Administration (FDA), its manufacturer claimed.

Singh, who has recently implanted the state-of-the-art device in two of his patients, said the technology is proving helpful for patients around the world, especially in therapies on difficult-to-reach parts of the human heart. Congestive heart failure is the inability to pump blood to the body's other organs with normal efficiency, a condition that affects over 10 million Indians.

Doctors said the most difficult part of implanting CRT devices is the part where a lead has to be piloted through the delicate and complex curves of the heart's anatomy.

" This is where the NASA-developed material comes to the rescue. It has superior electrical isolation qualities that enables to have the thinnest lead body in the world. This makes the lead much easier to position, which is clearly better for the patient on the operating table, and for their longer-term health,"added Dr Singh.
