Rheumatoid arthritis causes pain, swelling, and stiffness that can make daily life difficult. Many treatments require frequent doctor visits, which can be time-consuming and inconvenient for patients. This project focuses on creating an implantable drug delivery system to give patients more control over their treatment. The system includes an implant that a doctor places during an initial visit, which slowly releases cortisone over several months. When the medication runs out, patients can use a simple handheld applicator to refill the implant at home. The applicator is designed to be easy to use, with features like guided alignment (using light, sound, or vibration) and safety buttons to prevent accidents. By reducing the need for doctor visits and making treatment easier, this system aims to improve the quality of life for arthritis patients while ensuring safety and reliability.
