Cardiovascular Medical Device
Cardiovascular medical devices encompass a wide range of technologies designed to support or replace damaged cardiac structures and regulate the heart’s electrical activity. This field has seen a revolutionary shift from traditional open-heart surgery toward endovascular interventions, which utilize catheters to deploy stents, valves, and pacing leads with precision.
Devices such as implantable cardioverter defibrillators (ICDs) and pacemakers have become increasingly sophisticated, incorporating algorithms that can distinguish between life-threatening arrhythmias and normal sinus tachycardia. This ensures that therapeutic electrical discharges are only delivered when absolutely necessary, thereby preserving battery life and reducing patient discomfort during long-term device management.
The development of Transcatheter Aortic Valve Replacement (TAVR) technology represents a pinnacle of cardiovascular engineering. These valves are constructed from biological tissues, such as bovine or porcine pericardium, mounted on a nitinol frame that can be compressed into a small delivery sheath. Once positioned within the diseased native valve, the frame expands,…
