Conduit device and system for implanting a conduit device in a tissue wall
First Claim
1. A method for establishing fluid communication between a first surface and a second surface of a tissue wall, the method comprising:
- engaging the tissue wall with a conduit device such that a substantially fluid-tight seal is established between the conduit device and the tissue wall, the conduit device comprising an outer tube formed of a substantially rigid material; and
after engaging the tissue wall with the conduit device, advancing a coring device through the outer tube of the conduit device and through the tissue wall to core an aperture in the tissue wall extending from the first surface to the second surface of the tissue wall while maintaining the substantially fluid-tight seal between the conduit device and the tissue wall.

Abstract
Various embodiments of the present invention provide a conduit device including an attaching device configured for defining a helical pathway through a tissue wall and complementary ring in cooperation for securing the device within an aperture defined in the tissue wall. Some embodiments of the present invention further provide a system for implanting a conduit device in a tissue wall. More specifically, some embodiments provide a system including a coring device for defining an aperture in a tissue by removing and retaining a tissue core and securely implanting a conduit device therein so as to provide fluid communication between a first and second surface of the tissue wall via the conduit device.
