Surgical inserts are medical devices used to treat a variety of conditions. The two most common types of surgical inserts are stents and IMPLANTS. Stents are small, tube-shaped devices that are inserted into a blood vessel or other body cavity to keep it open and allow for better blood flow. IMPLANTS are larger devices that are surgically placed inside the body to replace or support a damaged or missing organ or tissue. Both stents and IMPLANTS are used to treat a variety of conditions, including heart disease, cancer, and joint pain.
