Abstract
A method of placing a cardiac drainage cannula into a patient's heart is provided. The method may comprise the steps of (a) inserting the cannula percutaneously into an internal jugular vein, (b) advancing the cannula through the internal jugular vein and into the right atrium of the heart, and (c) advancing the cannula through the atrial septum into the left atrium of the heart. A method of draining blood from the left atrium or left ventricle of a patient's heart using a cardiac drainage cannula is provided. A cardiac drainage cannula and a mechanical circulatory support system are also provided.
Claims27
A cardiac drainage cannula for draining blood from a heart, the cardiac drainage cannula comprising:
- an elongate body including a proximal end portion, a distal end portion, and at least one lumen extending along a length and through the elongate body from the distal end portion to the proximal end portion, the cannula comprising at least one inlet at the distal end portion of the elongate body and at least one proximal outlet at the proximal end portion of the elongate body, the at least one inlet being in fluid communication with the at least one outlet via the at least one lumen, wherein the at least one lumen of the elongate body includes:
- a right atrial pressure line extending from a proximal outlet of the right atrial pressure line at the proximal end portion of the elongate body to a right atrial inlet of the right atrial pressure line located at the distal end portion of the elongate body at a fixed position along the length of the elongate body,
- a left atrial pressure line extending from a proximal outlet of the left atrial pressure line at the proximal end portion of the elongate body to a left atrial inlet of the left atrial pressure line located at the distal end portion of the elongate body at a fixed position along the length of the elongate body,
- and
- a left ventricular pressure line extending from a proximal outlet of the left ventricular pressure line at the proximal end portion of the elongate body to a left ventricular inlet of the left ventricular pressure line located at the distal tip of the elongate body at a fixed position along the length of the elongate body.
