Engineered Pericardium and Derivatives for Uses in Medicine, Pharmaceuticals, Food and Cosmetics
S. Guhathakurta and V. Balasubramanian
Patent Not Granted
Indian Patent Application Number
138 / CHE / 2014
Reason Patent Was Not Granted
Patent Not Granted. Citing a publication from the lab could be used to derive the product.
What This Innovation Does
A tissue engineered indigenous pericardial patch has the property of regeneration and integration in the body and ease of handling by the surgeons.
Real-World Impact and Context
Presently India imports 100% of biological origin surgical patches which have limited versatility and are inadequate in meeting the demands. A tissue engineered indigenous pericardial patch has the property of regeneration and integration in the body and ease of handling by the surgeons. The innovation will provide cardiac patches for cardiac surgeries at very low cost as compared to current imported patches making the treatment available to those who cannot afford it.
