Abstract
An improved vascular incisor and method for allowing a user to safely create an incision in a body lumen. The present invention provides an apparatus which can create an incision in a front wall of the ascending aorta while preventing the blade from creating an incision in surrounding body structures, such as the back wall of the ascending aorta. The incisor includes a surgical element such as a blade which is activated by an actuator. As the actuator is depressed, the blade is moved from a protected, retracted position to an exposed, deployed position. The exposed blade is pushed into a front wall of the ascending aorta to create an incision. As the actuator is depressed further, the blade is automatically moved to the retracted position to prevent the blade from incising the back wall of the aorta.
