A heart device that helps in construction of grafts for bypass surgery simple and cost-effective has been granted Intellectual Patent Rights for novel design.

The device called the mammary artery surgical platform (MASP) has been designed and developed by Dr Lokeswara Rao Sajja of Star Hospitals and Mr Naga Srinivasa Sravan Kumar Manchikanti of 8C Healthcare Pvt. Ltd.

At present, bypass graft surgery is done using a (left) internal mammary artery and leg vein grafts. The standard technique is called coronary bypass surgery.

However, recent studies have shown that use of both right and left internal mammary arteries (artery of the chest wall) in bypass increases the longevity of heart patients.

Technical difficulties in constructing the ‘Y’ graft and other associated problems after use of both mammary arteries have limited the use to 4-5 per cent globally.

To overcome this difficulty, the novel device called MASP was designed by Dr Lokeswara Rao, a cardiothoracic surgeon and Mr Sravan Kumar. It helps surgeons to construct both ‘Y’ and ‘T’ grafts faster using both mammary arteries.

The potential to use the device is immense, as Indians are more prone to developing coronary artery disease at a young age compared to westerners. The use of both mammary arteries offers long-term survival of heart patients, Dr Lokeswara Rao, said in a release.

Dr Rao said the design IPR granted by the Indian Patent Office confers rights for 10 years. It gives exclusivity to use, make sell and market the design. The Andhra Pradesh Technology Development & Promotion Centre facilitated the design registration.
