Abstract

See full text

System and method for bi-directional fluid injection includes a retrograde introducer, a retrograde cannula having an inlet opening, intermediate opening and outlet opening, an antegrade introducer and an antegrade cannula. The retrograde introducer is configured to engage with the retrograde cannula and to insert the retrograde cannula into a fluid channel. The antegrade introducer is configured to engage with the antegrade cannula and to insert the antegrade cannula into the fluid channel from within the retrograde cannula through the intermediate opening. After insertion of both cannulas, both introducers are removed. In operation, fluid flows into the retrograde cannula inlet and a portion thereof is diverted to the antegrade cannula which flows the portion in a first direction in the channel, the remainder of the fluid flows out the retrograde cannula outlet in an opposite direction in the channel. The system is removed from the channel using the introducers in reverse order.
