Abstract

Various aspects of the present disclosure are directed toward apparatuses, methods and systems for improving or assisting cardiac function of a patient. The apparatuses, methods and systems may include a support structure configured to extend across leaflets of an aortic valve of the patient. In addition, the support structure may be configured to removably couple a pump.

Claims

1. A medical device for improving or assisting cardiac function of a patient, the medical device comprising:

a support structure configured to extend across leaflets of a valve of the patient, the support structure having a delivery configuration and a deployed configuration; and

one or more locating features arranged within an interior of the support structure and configured to removably couple a pump to the support structure in the deployed configuration.

2. The medical device of claim 1, further including a pump is configured to drive blood flow through the support structure and supply blood flow to an aorta and couple to the one or more locating features of the support structure.

3. The medical device of claim 2, wherein the support structure is configured to removably couple the pump after the support structure is deployed from the delivery configuration to the deployed configuration and the pump includes one or more engagement elements configured to lock within the one or more locating features of the support structure.

4. The medical device of claim 3, wherein the pump and the support structure form a seal therebetween to stop blood flow between the pump housing and the support structure.

5. The medical device of claim 3, wherein the support structure is configured to suspend the pump within the support structure to allow blood flow about the pump.

6. The medical device of claim 2, wherein the support structure is configured to pin the leaflets to heart tissue in an open position to minimize interference with the pump.

7. The medical device of claim 2, further including a controller configured to power the pump and a drive line coupled to the pump and the controller and configured to deliver power to the pump.

8. The medical device of claim 7, wherein the drive line is configured to route through one of the left or right subclavian arteries.

9. The medical device of claim 1, wherein the support structure includes at least one of a stent and a graft configured to collapse to the delivery configuration and engage and interface with the leaflets of the valve upon expansion of the support structure to the deployed configuration.

10. A modular system for assisting cardiac function of a patient, the system comprising:

a support structure configured to deploy at a target treatment region within the patient, the support structure including one or more locating features arranged within an interior of the support structure;

a pump including one or more engagement elements configured to removably couple to the locating features of the support structure after deployment of the support structure at the target treatment region; and

a power source configured to power the pump to drive blood flow through the support structure.

11. The system of claim 10, wherein the power source includes a controller configured to power the pump and a drive line removably coupled to the pump and the controller configured to deliver the power to the pump.

12. The system of claim 11, wherein the drive line is configured to route through one of the left or right subclavian arteries and couple to the pump after deployment of the pump within the support structure.

13. The system of claim 10, wherein the power source includes an extracorporeal control system configured to control operation of the pump and to wirelessly power the pump.

14. The system of claim 13, wherein the extracorporeal control system includes a transcutaneous energy transmission system configured to wireless transmit energy to the pump.

15. The system of claim 14, wherein the pump includes an antenna configured to receive the transcutaneous energy transfer.

16. A method of improving or assisting cardiac function of a patient, the method comprising:

deploying a pump system across leaflets of a valve of the patient, the pump system including a support structure having one or more locating features arranged within an interior of the support structure and a pump including one more engagement features configured to removably couple to the one or more locating features of the support structure; and

operating the pump to drive blood flow through the support structure.

17. The method of claim 16, wherein the operating the pump includes driving blood across the pump and into an aorta.

18. The method of claim 17, wherein operating the pump includes drawing blood from a left ventricle and across the pump into the aorta.

19. A method of delivering a medical device for assisting cardiac function of a patient to a target location, the method comprising:

deploying a support structure at a target treatment region within the patient, the support structure including one or more locating features arranged within an interior of the support structure;

arranging a pump within the support structure, the pump including one or more engagement elements; and

coupling the pump to the support structure by engaging the locating features of the support structure and the engagement elements of the pump.

20. The method of claim 19, further comprising coupling a power source to the pump.

21. The method of claim 20, wherein the power source includes a controller configured to power the pump and coupling the power source to the pump includes coupling a drive line to the pump and the controller configured to deliver the power to the pump.

22. The method of claim 21, wherein coupling the drive line to the pump includes routing the driveline through one of the left or right subclavian arteries and couple to the pump after coupling the pump to the support structure.

23. The method of claim 20, wherein the coupling a power source to the pump includes wirelessly coupling an extracorporeal control system to the pump to control operation of the pump and to wirelessly power the pump

24. The method of claim 19, wherein deploying the pump system includes arranging the support system through one of a femoral access, a subclavian access, or transcaval access.
