Abstract
A disclosed apparatus or method can include or use a non-transluminally implantantable blood pump housing, which can be sized and shaped to be implanted at an aortic valve of a human subject, the pump housing can include: a pump housing cross-sectional profile size that is larger than is passable via a blood vessel of the human subject; and a power connection, configured for being electrically connected to an intravascular lead that is sized and shaped to extend from the pump housing through a subclavian artery of the human subject.
Claims17
An aortic valve or ascending aorta apparatus, comprising:
- a transapically implantable blood pump housing that is sized and shaped to be implanted and operate at an aortic valve or ascending aorta of a human subject, the pump housing including:
- a blood pump including an impeller;
- a pump housing cross-sectional profile size that is larger than 16 millimeters so as to be larger than passable via a blood vessel of the human subject other than the aorta;
- and
- a power connection including a power connector accessible from an outflow side of the blood pump housing, the power connection being electrically connected to an intravascular lead that is sized and shaped to extend from the pump housing, when the pump is positioned at the aortic valve, through a subclavian artery of the human subject.
An aortic valve or ascending aorta apparatus, comprising:
- a transapically implantable blood pump housing that is sized and shaped to be implanted and operate at an aortic valve or ascending aorta of a human subject, the pump housing including:
- a blood pump including an impeller;
- a pump housing cross-sectional profile size that is larger than 16 millimeters so as to be larger than passable via a blood vessel of the human subject other than the aorta;
- and
- a power connection including a power connector accessible from an outflow side of the blood pump housing, the power connection being electrically connected to an intravascular lead that is sized and shaped to extend from the pump housing, when the pump is positioned at the aortic valve, through a subclavian artery of the human subject;
- and
- a guidewire configured to be connected to the intravascular lead in the left ventricle of the human subject or external to the heart or external to the human subject.
An aortic valve or ascending aorta blood pump apparatus, comprising:
- a transapically implantable blood pump housing, sized and shaped to be implanted at an aortic valve or ascending aorta of a human subject, the pump housing including:
- a pump housing cross-sectional profile size that is larger than is passable via a blood vessel of the human subject other than the aorta, wherein the blood pump cross sectional profile is larger than 16 millimeters and includes an axial impeller that is longitudinally arranged between a blood inlet and a blood outlet, whereby the axial impeller is sized, shaped, and otherwise configured to be capable of pumping at least 1.5 liters, preferably at least 3 liters of blood per minute;
- an intravascular lead that is sized and shaped to extend from the pump housing through the subclavian artery of the human subject;
- and
- a power connection configured for being electrically connected to the intravascular lead that is sized and shaped to extend from the pump housing through a subclavian artery of the human subject;
- a user-expandable anchor that is affixed or coupled to the blood pump housing, whereby the anchor sized and shaped to be located at and expanded to be anchored to an aortic valve of the human subject to secure the blood pump housing at the aortic valve of the human subject to pump at least 1.5 liters per minute;
- and
- a guidewire configured to be connected to the intravascular lead in the left ventricle of the human subject or external to the heart or external to the human subject.
