摘要：
An apparatus and method for connecting a first conduit to the heart without cardiopulmonary bypass. The first conduit may be attached to a second conduit having a prosthetic device interposed. The second conduit may then be connected to the aorta. The prosthetic device may be a prosthetic valve (or pump). The apparatus includes an implantable connector with first conduit component, a coring component, a retractor expansion component slidably coupled to the coring component, and a pushing component. The retractor expansion component seats against and separates the inside wall of the left ventricle so that the coring component cuts cleanly through the myocardium, forming a tissue plug. By remaining seated against the inside wall, the retractor expansion component follows the tissue plug into the coring component. The surgeon applies force and rotary motion to the pushing component sufficient to cut the tissue plug and implant the prosthetic component.
