Abstract
A hands-free mitral papillary muscle exposure device provides a clear view of the papillary muscles, including the pathology of the leaflets and chordae tendineae of a mitral valve apparatus, and comprises a retractor device comprises two arm members pivotally connected to one another which can be manually spread and adjusted about a pivot point to a desired arrangement relative to the mitral valve apparatus to prevent injury to surrounding muscle and tissue during an operative procedure. Each arm member includes a respective downwardly extending longitudinal projection to hold one of the anterior and posterior leaflets adjacent to said arm member when the retractor device is positioned relative to the mitral valve apparatus. The longitudinal projection on the anterior side of the retractor device is longer than the corresponding longitudinal projection on the posterior side to accommodate the longer size of the anterior leaflet in comparison with the posterior leaflet.
