The Future of Cardiovascular Stents: Bioresorbable and Integrated Biosensor Technology

Area of Science:

• Cardiovascular medicine
• Biomedical engineering
• Nanotechnology

Background:

• Cardiovascular disease (CVD) is the leading global cause of mortality, with atherosclerosis underlying two-thirds of these deaths.
• Atherosclerosis, or "furring of the arteries," is an age-dependent process exacerbated by lifestyle factors and genetics, often inadequately managed by current drugs.
• In-stent restenosis, a wound response causing re-narrowing of stented arteries due to smooth muscle cell hyperplasia, remains a significant clinical challenge.

Purpose of the Study:

• To review current stent technologies for treating blocked arteries.
• To explore the potential of novel biosensing devices for overcoming in-stent restenosis.
• To discuss the integration of biosensors into stents and future implantable medical devices within the Internet of Things framework.

Main Methods:

• Review of current literature on stent technology and in-stent restenosis.
• Analysis of advances in nanofabrication for biosensing applications.
• Discussion of emerging trends in implantable medical devices and the Internet of Things.

Main Results:

• Current stent technology faces limitations in preventing in-stent restenosis.
• Advances in nanofabrication enable new sensing methods for potential integration into stents.
• The Internet of Things paradigm is poised to significantly influence future biosensor technology for implantable devices.

Conclusions:

• There is an urgent need for improved clinical interventions to manage atherosclerosis and its complications.
• Integrating biosensors into stents offers a promising future strategy to combat in-stent restenosis.
• The convergence of biosensing, nanofabrication, and the Internet of Things heralds a new era for cardiovascular device technology.
