ABSTRACT:
An atriotomy access adaptor for use in open-heart surgery consists of a polymeric foam base adapted to fit into an incision in the atrium. Venous uptake cannulas are inserted through incisions made in the foam adaptor base and are held in place by two loops fastened to the foam body which are adapted to allow the downward positioning of the cannulas into the atrium, but which resist withdrawal of the cannulas. Also attached to the foam base is a tab containing an elastomeric band attached to one end. When the adaptor base is inserted into the atrium the rubber band is wound around and over the atrial tissues at the point of incision insuring a snug fit of the adaptor base around the cannulas and securing the atrium around the adaptor base. The end of the elastomeric band is then anchored to the tab.
