PERCUTANEOUS BYPASS BY TUNNELING THROUGH VESSEL WALL

摘要

A parent vessel (16) lies adjacent heart tissue, and a restriction (24) in the parent vessel (16) is bypassed. A first region of the parent vessel (16) on a first side of the restriction (24) is accessed and an aperture is formed therein. A lumen (40) is formed through the heart tissue, and the lumen (40) communicates with the parent vessel (16) through the first aperture. A second aperture is formed in a second region of the parent vessel (16) on a second side of the restriction (24). The lumen (40) through the heart tissue communicates with the parent vessel (16) through the first and second apertures, thus bypassing the restriction (24).
