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

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.

Methods and systems for irrigating and capturing particulates during heart pump implantation

A method and apparatus for measuring and controlling the size of drops of viscous material dispensed from a dispensing system. A dispensing apparatus in accordance with embodiments of the present invention includes a housing, a dispenser that dispenses a quantity of the viscous material, a measuring apparatus having a bottom plate to receive the viscous material, a top plate that is positioned over the bottom plate after the viscous material has been dispensed, and a compressing apparatus that compresses the material between the top and bottom plates. The dispensing apparatus further includes a viewing system that views the compressed material to determine the quantity of material dispensed by the dispenser. In one embodiment, the dispensing apparatus includes a controller that controls the quantity of viscous material dispensed based on the quantity of material determined by the viewing system.

Method and apparatus for measuring the size of drops of a viscous material dispensed from a dispensing system

A dispensing system for dispensing a quantity of material includes an inlet port to receive the material, an outlet port from which the material is dispensed from the dispensing system, a housing having an inner chamber with an adjustable volume, a first valve operable in one of an open mode of operation and a closed mode of operation. The first valve is disposed between the inlet port and the inner chamber in such a manner that when the first valve is operating in the open mode, material may flow from the inlet port into the inner chamber, and when the first valve is operating in the closed mode, material is prevented from flowing from the inlet port into the inner chamber. The dispensing system also includes a second valve operable in one of an open mode of operation and a closed mode of operation. The second valve is disposed between the outlet port and the inner chamber in such a manner that when the second valve is operating in the open mode, material may flow from the inner chamber to the outlet port, and when the second valve is operating in the closed position, material is prevented from flowing from the inner chamber to the outlet port.
