Abstract
Official abstract text for this publication.
A coring knife can be used to make a circular incision. The coring knife includes an abutment that is inserted into an initial slit through the heart wall. The abutment can be inserted into the slit while oriented in a direction that minimizes its insertion profile. After insertion, the abutment is reoriented by turning a key so that its abutment surface faces toward a circular cutting edge of the coring knife on the other side of the heart wall. The circular incision through the heart wall is made by pressing the circular cutting edge of the coring knife against the abutment.
