Abstract

A blood circulation assist system comprising an inflow cannula having a lumen and an insertion device configured to be received therein and to facilitate insertion of a portion of the inflow cannula into a heart chamber. The insertion device includes a shaft having distal and proximal end portions and a plurality of lumens. A first lumen is configured to receive a guidewire and a second lumen is configured to receive a pressurized fluid. A tip connected to the distal end portion of the shaft is configured for insertion into the heart chamber. The tip has a hollow interior communicating with the first shaft lumen. An inflatable member is coupled to the distal end portion of the shaft and includes a hollow interior in fluid communication with the second shaft lumen. The inflatable member is movable between deflated and inflated configurations for releasably securing the insertion device to the inflow cannula.
