US 2015/0173734 A1 · APPARATUS AND METHOD FOR CONNECTING A CONDUIT TO A HOLLOW ORGAN

Abstract

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.

A method for using an applicator to form a hole in a wall of a hollow organ and insert a connector conduit into the hole, said applicator comprising a hole forming element having a cutting element on a distal end thereof and being coupled to the connector conduit with a distal end of said connector conduit being adjacent said cutting element, a retractor element having an expansion element, and sequencing means for coordinating the relative movement of said retractor element with respect to said hole forming element, said method comprising:

a) inserting a distal end of the retractor element through a slit formed in the wall of the organ while the retractor element is locked in a fully extended position relative to the hole forming element and the expansion element is in an unexpanded state
b) expanding the expansion element to a fully expanded state and moving the expansion element toward the hole forming element;
c) forming the whole with the cutting element and inserting the connector conduit into the hole by manipulating the hole forming element while the expansion element presses the tissue toward the cutting element;
d) decreasing the size of the expansion element to a partially expanded state and moving the expansion element to be at least partially disposed in the hole forming element;
and
e) decoupling the applicator from the connector conduit to remove the applicator while the connector conduit remains in the hole.
