The invention relates generally to methods and systems for irrigating particulates during heart pump implantation, and more specifically relates to irrigating and removing particulates that may be released when coring a patient's heart tissue. A method of irrigating particulates during blood pump implantation includes inserting a removable tissue irrigating device into a patient's heart. The removable tissue irrigating device includes a delivery tube and an irrigation conduit extending through the delivery tube. The irrigation conduit is extended out of an opening in the delivery tube to a deployed position from a stored position. 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. Fluid is dispersed from the irrigation conduit into the patient's heart to remove particulates released during and/or after a coring procedure.

Methods and systems for irrigating particulates during heart pump implantation

Disclosed herein is an inflow cannula for an implantable blood pump assembly. The inflow cannula includes a tubular body that extends from a proximal end to a distal end. The tubular body includes a proximal portion adapted for connection to a pump housing, and a distal portion adapted for positioning within an opening formed in a heart. The inflow cannula further includes an expandable sleeve coupled to an exterior surface of the distal portion. The sleeve has a first portion coupled to the distal portion of the tubular body, and a second portion extending from the distal end of the tubular body. The second portion is deployable from a first, stored configuration to a second, deployed configuration in which the second portion expands radially to engage and conform to an endocardial surface of the heart.

The invention relates generally to methods and systems for irrigating or capturing particulates during heart pump implantation, and more specifically relates to irrigating, capturing, and removing particulates that may be released when coring a patient's heart tissue. In one aspect, a method for capturing particulates during heart pump implantation is provided that includes inserting a removable particulate capture device into a patient's heart prior to a coring procedure upon the patient's heart. The removable particulate capture device includes an expandable basket movable between collapsed and expanded configurations. The method further includes expanding the expandable basket to the expanded configuration from the collapsed configuration when the removable particulate capture device is positioned within the patient's heart to capture the particulates released during the coring procedure. The method includes removing the expandable basket with the captured particulates from the patient's heart through a cored opening.
