ABSTRACT:
A device and procedure are provided which enable the attachment of a hollow cylindrical atriotomy button to, for example, the atrial appendage. The inventive device, which carries on its end the inner portion of an atriotomy button, is inserted through an incision in the hollow organ. When the device is triggered, the outer portion of the atriotomy button is forced over the inner portion. Sharp points, which are formed on the edge of the inner section, grasp and guide the walls of the incision during the operation of the device so that the walls are effectively clamped between the two button portions. After the button is in place, a cannula can be inserted into the heart through the access button or attached to the outer surface of the outer button portion.
