Cardiovascular medical devices are essential tools in the management of heart disease, designed to monitor, support, or restore the heart's natural rhythm and blood flow. These devices range from simple implants to complex electronic systems that can respond automatically to changes in cardiac activity.

Pacemakers and implantable cardioverter-defibrillators (ICDs) are used to treat electrical issues, delivering pulses to keep the heart beating at a regular rate or providing a shock to stop a dangerous arrhythmia. For structural issues, stents are used to keep arteries open after they have been narrowed by plaque.
