A heart valve prosthesis sizer handle is a reusable surgical tool used during cardiac procedures to assist in measuring the patient’s valve opening (annulus). Surgeons attach an interchangeable sizer to the handle to evaluate the correct size for an annuloplasty ring or replacement valve before implantation, ensuring proper fit and function.
These devices are typically made of metal or plastic and may feature straight, curved, rigid, or flexible designs. Regulation varies by jurisdiction, but they are generally classified as surgical instruments and subject to medical device standards for safety and performance in cardiac surgery.
