SCTIMST Unveils 'Chitra Core' Indigenous Low-Metal Coronary Stent

Sree Chitra Tirunal Institute for Medical Sciences and Technology (SCTIMST), Trivandrum, an autonomous institute under the Department of Science and Technology, has developed an indigenous coronary stent named 'Chitra Core'. The medical device features a patented structural design that uses 30 to 40 per cent less metal than conventional cardiac stents available in the global market, marking a significant advancement in domestic cardiovascular medical technology.

Coronary artery stents are tiny expandable mesh tubes inserted into clogged arteries to restore normal blood flow. Conventional metal stents often pose risks of long-term complications, including in-stent restenosis (re-narrowing of the artery due to tissue overgrowth) and stent thrombosis (formation of dangerous blood clots). SCTIMST engineered the Chitra Core stent to minimize these clinical complications by optimizing strut thickness and improving vessel wall compliance.

Cardiovascular diseases remain the leading cause of mortality in India, driving high demand for affordable angioplasty hardware. By reducing reliance on imported cardiac devices, Chitra Core aligns with the National Medical Devices Policy 2023, which aims to boost self-reliance in high-end medical equipment. Rigorous pre-clinical trials demonstrated superior re-endothelialization rates and structural stability compared to imported cobalt-chromium and platinum-chromium drug-eluting stents.

For civil services aspirants, this development is crucial for GS Paper III (Indigenization of Technology and Public Health). Prelims MCQs frequently cover autonomous research institutes like SCTIMST and biomedical innovations, while Mains questions evaluate India's health technology ecosystem and strategies to reduce out-of-pocket healthcare expenses.
