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 hernodynarnic 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.

Claims

1. (canceled)

2. (anceled)

3. A method for providing hemodynamic support to a patient, said method comprising:

providing a hemodynamic support catheter having a proximal end, a distal end, an inlet lumen and an outlet lumen;

introducing the hemodynamic support catheter into a vein of the patient;

advancing the hemodynamic support catheter in an antegrade direction through the vein toward a tight atrium of the patient;

transseptally delivering the hemodynamic support catheter into an aorta of the patient;

removing blood from the patient via the inlet lumen and delivering the blood to a hemodynamic support pump; and

returning the blood from the hemodynamic support pump to the aorta via the outlet lumen.

4. The method of claim 3, further comprising alleviating workload on a heart of the patient.

5. The method of claim 3, wherein the blood exits the outlet lumen from an outlet port, and wherein the blood enters the inlet lumen from an inlet port, and wherein the outlet port is distal of the inlet port.

6. The method of claim 3, wherein the outlet port comprises a plurality of outlet ports disposed adjacent the distal end of the hemodynamic support catheter, and wherein the inlet port comprises a plurality of inlet ports proximal of the plurality of outlet ports,

7. The method of claim 3, wherein the vein comprises an internal jugular vein or a subclavian vein.

8. The method of claim 3, wherein transseptally delivering the hemodynamic support catheter into the aorta comprises advancing the hemodynamic support catheter from the right atrium of the patient transseptally into a left atrium of the patient, crossing a mitral valve of the patient and passing the hemodynamic support catheter through a left ventricular outflow tract of the patient into the aorta.

9. The method of claim 3, wherein the hemodynamic support catheter consists of a single catheter having the inlet lumen and the outlet lumen.

11. The method of claim 3, wherein the hemodynamic support catheter comprises a plurality of axially oriented elongate elements adjacent the distal end thereof, the method further comprising radially expanding the plurality of elongate elements thereby forming a barrier around the distal end of the hemodynamic support catheter.

10. The method of 3, wherein the hemodynamic support catheter comprises an inlet catheter and an outlet catheter, wherein the inlet lumen is disposed in the inlet catheter and the outlet lumen is disposed in the outlet catheter, and wherein the outlet catheter is slidably disposed in the inlet catheter.

12. A hemodynamic support system, said system comprising:

a hemodynamic support pump configured to alleviate workload from a heart of a patient;

an inlet catheter having a proximal end, a distal end, and an inlet port adjacent the distal end of the inlet catheter, the inlet catheter configured to be delivered in an antegrade direction through a vein toward the heart and the inlet catheter fluidly coupled to the hemodynamic support pump; and

an outlet catheter having a proximal end, a distal end, and an outlet port adjacent the distal end of the outlet catheter, the outlet catheter configured to be delivered in an antegrade direction through the vein into an aorta of the patient, and the outlet catheter fluidly coupled to the hemodynatnic support pump,

wherein the outlet catheter is slidably disposed in the inlet catheter such that the outlet port is distal of the inlet port, and

wherein the inlet catheter is configured to remove blood from the patient and deliver the blood to the hemodynamic support pump, and

wherein the hemodynamic support pump is configured to pump the blood back to the patient via the outlet catheter, thereby alleviating the workload from the heart.

13. The system of claim 12, wherein the outlet port comprises a plurality of outlet ports disposed adjacent the distal end of the outlet catheter, and wherein the inlet port comprises a plurality of inlet ports on the inlet catheter, the plurality of inlet ports proximal of the plurality of outlet ports.

14. The system of claim 12, wherein the inlet catheter comprises a plurality of axially oriented elongate elements adjacent the distal end thereof forming a barrier around the inlet port to prevent obstruction thereof

15. The system of claim 12, wherein the inlet catheter comprises a flared region adjacent the distal end thereof

16. The system of 12, wherein the proximal end of the inlet catheter comprises a Y-shaped region having a first port and a second port, and wherein the first port is configured to receive the outlet catheter, and wherein the second port is fluidly coupled with the hemodynamic support pump.
