Abstract: A cutting edge of a punch includes side segments and a central segment disposed between the side segments. When the punch head slides into a hollow blade, the central segment of the cutting edge meets the punch head before the side segments meet the punch head. The central segment starts cutting first, which can help avoid a dog-bone shaped hole when the punch is used on a blood vessel, such as the aorta.

Abstract: A coring knife can be used to make a circular incision. The coring knife can include an abutment that can be inserted into heart tissue. The circular incision is made by pressing the circular cutting edge of the coring knife against the abutment.

Abstract: A coupling system includes an applicator tool and an attachment ring mounted on the applicator tool. Clips are contained within the applicator tool and are deployed through the attachment ring in order to anchor the attachment ring to biological tissue. When deployed, tips of the clips follow a curved trajectory through an annular cuff of the attachment ring and through the underlying tissue. The tips loop back out of the tissue and to a location where they are later trapped or clamped by the attachment ring. While the tips are trapped or clamped, the applicator tool cinches the clips by pulling rear segments of the clips. Thereafter, the applicator tool disconnects from the attachment ring which remains anchored to the tissue and serves as a coupling for a cannula. The cannula can have movable lock members that secure it to the attachment ring.
