📄 About This Patent
Patent No. 517820 protects the SMILE Mesh — a novel mesh prosthesis design invented by Dr. Ashwin Porwal for use in open umbilical and inguinal hernia repair surgeries.
Conventional hernia mesh designs carry risks of post-operative chronic pain, mesh shrinkage, migration, and recurrence. The SMILE Mesh addresses these limitations through a proprietary design that optimises the balance between flexibility, tensile strength, and tissue integration.
The patent covers the structural geometry, material specification, and edge-finishing process of the mesh — each element contributing to reduced surgical trauma, improved tissue adherence, and superior long-term hernia recurrence outcomes compared to standard commercially available meshes.
✓ Key Innovation Points
✔ Novel mesh geometry designed specifically for Indian patient anatomy
✔ Reduces chronic post-operative groin pain compared to standard flat mesh
✔ Validated in randomized clinical trial vs. Lichtenstein repair (2016)
✔ Applicable for both umbilical and inguinal hernia repairs
