Materials advancements for the safety and patency of implantable cardiovascular devices.

Implantable cardiovascular devices have revolutionized the management of cardiovascular diseases, significantly enhancing patients' quality of life. With the increasing demand of cardiac implantable electronic devices, the imperative for novel device development is evident. This review article first elaborates the mechanisms underlying foreign body response and infection, elucidating the complex interplay between implanted constructs and host tissues. The discussion then focuses on current advancements in materials science and engineering aimed at mitigating these challenges. Material innovations, such as drug-eluting materials, surface modifications, and biomimetic materials, are explored as strategies to modulate these responses and to prevent fibrotic or thrombotic complications and infection. Finally, future directions in materials development for implantable cardiovascular devices are introduced. By addressing safety and patency concerns through innovative material strategies, this article aims to guide the research and development of advanced materials for both current and future cardiovascular implantable devices, ultimately improving patient outcomes and advancing cardiovascular disease treatment.
