1. A method of irrigating particulates during blood pump implantation, the method comprising:
inserting a removable tissue irrigating device into a patient's heart, wherein the removable tissue irrigating device comprises a delivery tube and an irrigation conduit extending through the delivery tube;
extending the irrigation conduit out of an opening in the delivery tube to a deployed position from a stored position, wherein the irrigation conduit is substantially disposed within the delivery tube when in the stored position and has a distal portion protruding out of the delivery tube when in the deployed position;
dispersing fluid from the irrigation conduit into the patient's heart to remove particulates released during and/or after a coring procedure; and
removing the removable tissue irrigating device from the patient's heart.
