1. Invented VAO, (VETTATH ANASTAMOTIC OBTURATOR) which is a device used for performing the proximal anastamosis of the vein graft to the aorta, without using the side clamp. This avoids the escape of calcium and debris to the brain, there by preventing stroke and neurocognitive defects during beating heart surgery.
   
   This product is in the process of being patented. This is an anastomosis enabling device, where in, the surgeon is able to perform the usual anastomosis with sutures. This is a novel, cost effective and a locally made device, which is a better alternative to the expensive Anastomotic devices available in the international market today.

2. AORTO CORONARY SHUNT - Developed and Fabricated our own indigenous Aorto - Coronary Shunt in 1999 at Dhaka, Bangladesh , which is used to perform beating heart surgery in patients with tight left main disease. This was presented at the Fourth Annual Scientific Meeting of The International Society for Minimally Invasive Cardiac Surgery held in June 27 - 30, 2001 in Munich, Germany.
3. A Prototype of the first Indian Stabiliser for Beating Heart Surgery has been fabricated and  is in its final stage of completion. 
4. Fabricated our own Blower mister device which is used in OPCABs  routinely.
5. Fabricated our indigenous cost effective Blood Cardioplegia system for Open-Heart Surgery.
6. Fabricated our modified intracoronary shunt for long arteriotomy and mammary patch  from aortocoronary shunts.
7. Fashioned and Standardised our own Technique of Long Mammary Patch Angioplasty without Endarterectomy for Diffusely Diseased Coronary Arteries.
