Antegrade hemodynamic support
First Claim
Patent Images
1. A method of providing hemodynamic support to a patient'"'"'s heart for alleviating workload therefrom, said method comprising:
- providing a hemodynamic support system, wherein the hemodynamic support system comprises a catheter, the catheter comprising at least two lumens and having an inlet port and outlet port, wherein the inlet port is proximal of the outlet port;
introducing the catheter into a vein of the patient;
advancing the catheter in an antegrade direction into a vena cava;
advancing the catheter in the antegrade direction into a right atrium;
passing the catheter transseptally from the right atrium into a left atrium;
advancing the catheter across a mitral valve;
advancing the catheter in the antegrade direction through a left ventricular outflow tract into an ascending aorta;
removing blood from the patient via the inlet port and through a first of the at least two lumens and delivering the blood to another portion of the hemodynamic support system;
returning the blood to the patient by delivering the blood through a second of the at least two lumens, wherein the blood is returned from the outlet port to the ascending aorta, the outlet port adjacent a distal portion of the catheter; and
alleviating the workload on the patient'"'"'s heart and supporting the patient'"'"'s normal body functions.

Abstract
The procedure to place antegrade hemodynamic support (AHS) combine currently available procedures and devices in a unique fashion to solve a significant problem for patients who need large bore hemodynamic support. The AHS procedure involves delivering an AHS device or a catheter connected to an AHS device to a patient'"'"'s aorta in an antegrade fashion, alleviating the workload on the patient'"'"'s heart and supporting the patient hemodynamically to maintain normal functions of the body organs.

4. A method of delivering hemodynamic support to a patient'"'"'s heart for alleviating workload therefrom, said method comprising:
-
providing a hemodynamic support system, wherein the hemodynamic support system comprises an outer catheter and an inner catheter, wherein the outer catheter comprises a first port, a second port, and a third port, wherein the inner catheter comprises an outlet port disposed on a distal portion thereof; introducing the outer catheter into a vein of the patient and advancing the outer catheter towards the heart; introducing the inner catheter into the first port; advancing the inner catheter through the outer catheter in an antegrade direction and out the third port, wherein the third port is disposed on a distal portion of the outer catheter; disposing the outlet port in an ascending aorta; removing blood from the patient via the third port or a plurality of apertures disposed on the distal portion of the outer catheter, wherein the third port or the plurality of apertures is proximal of the outlet port; moving the blood through the second port and delivering the blood to another portion of the hemodynamic support system; returning the blood to the patient by delivering the blood through the outlet port; and alleviating the workload on the patient'"'"'s heart and supporting the patient'"'"'s normal body functions. - View Dependent Claims (5, 6, 7, 8, 9, 10)

11. A method of providing hemodynamic support to a patient'"'"'s heart for alleviating workload therefrom, said method comprising:
-
providing a hemodynamic support system, wherein the hemodynamic support system comprises two separate catheters, an inlet catheter and an outlet catheter, the inlet catheter comprises an inlet port disposed on a distal portion thereof, the outlet catheter comprises an outlet port disposed on a distal portion thereof; introducing the outlet catheter into a vein of the patient; advancing the outlet catheter in an antegrade direction into an ascending aorta, wherein the outlet port is disposed in the ascending aorta; introducing the inlet catheter into a vein of the patient; advancing the inlet catheter proximal to the outlet port; removing blood from the patient through the inlet catheter via the inlet port and delivering the blood to another portion of the hemodynamic support system; returning the blood to the patient by delivering the blood to the ascending aorta through the outlet catheter via the outlet port; and alleviating the workload on the patient'"'"'s heart and supporting the patient'"'"'s normal body functions. - View Dependent Claims (12, 13, 14, 15, 16, 17)

18. A method of providing hemodynamic support to a patient'"'"'s heart for alleviating workload therefrom, said method comprising:
-
providing a hemodynamic support system, wherein the hemodynamic support system comprises a catheter system, a second catheter, a snare, and a guide wire; introducing the snare into an internal jugular vein or a subclavian vein of the patient; advancing the snare into an inferior vena cava; introducing the second catheter into a common femoral vein of the patient; advancing the second catheter through the snare; advancing the second catheter in an antegrade direction into a right atrium; passing the second catheter transseptally from the right atrium into the left atrium; advancing the second catheter across a mitral valve; advancing the second catheter in the antegrade direction through a left ventricular outflow tract into an ascending aorta; introducing the guide wire into the second catheter from the common femoral vein; advancing the guide wire through the second catheter to the ascending aorta; removing the second catheter from the patient while the guide wire remains in the patient; snaring the guide wire with the snare; externalizing the proximal portion of the guide wire from the internal jugular vein or the subclavian vein; introducing the catheter system into the internal jugular vein or the subclavian vein; and advancing the catheter system into the heart, wherein a distal portion of the catheter system is positioned in the ascending aorta. - View Dependent Claims (19, 20)
