    Biodesign Statement <\/mark><\/strong><\/p>\n\n\n\n

    A device for cardiothoracic surgeons to use to retract the leaflets of the mitral valve to increase visualization of and access to the sub<\/strong><\/em>–<\/strong><\/em>valvular structures during mitral valve repair surgery.<\/strong><\/em><\/p>\n\n\n\n

    Introduction<\/mark><\/strong><\/p>\n\n\n\n

    The Mitral Valve Papillary Ring<\/span> is a one-of-a-kind mitral valve retraction device that aids in visualization of and access to the sub-valvular structures during mitral valve repair surgery. The device allows for hands-free exposure of the surgical site without the added risk of valve leaflet damage that is present with current methods of exposure. We are committed to providing cardiothoracic surgeons with the best methods for exposure to ensure an efficient surgical process.<\/p>\n\n\n\n

    Problem<\/mark><\/strong><\/p>\n\n\n\n

    The most critical aspect of a successful procedure during mitral valve repair surgery is adequate surgical site visualization. Proper visualization allows surgeons to recreate the patient’s native anatomy and improve hemodynamic function for better surgical outcomes. The primary method of obtaining visualization is suturing of the mitral valve leaflets. The secondary solution is the use of a sterile ruler. A few competitive devices on the market are also designed for mitral valve retraction and provide an advantage over traditional methods by reducing surgical time. However, the devices are significantly more expensive than rulers or sutures. The images below show each of the current methods of visualization and their primary shortcomings. <\/p>\n\n\n\n
