Abstract

Devices and methods are configured to allow transcarotid or subclavian access via the common carotid artery to the native aortic valve, and implantation of a prosthetic aortic valve into the heart. The devices and methods also provide means for embolic protection during such an endovascular aortic valve implantation procedure.

Claims (32)

1 . A system for transcatheter aortic valve treatment, the system comprising:

an access sheath configured to be disposed in a carotid artery, the access sheath having a lumen formed therein;

a shunt having a first end region disposed within the carotid artery at a position downstream of the access sheath, the shunt being configured to provide blood from a secondary blood vessel to the carotid artery; and

a valve delivery system configured to pass through the lumen of the access sheath.

2 . The system of claim 1 , wherein the access sheath includes a second lumen.

3 . The system of claim 1 , wherein the access sheath includes a filter.

4 . The system of claim 1 , wherein the shunt comprises a second end region disposed within the secondary blood vessel.

5 . The system of claim 4 , wherein the secondary blood vessel includes a femoral artery.

6 . The system of claim 4 , wherein the secondary blood vessel includes a subclavian artery.

7 . The system of claim 4 , wherein the secondary blood vessel includes a contralateral carotid artery.

8 . The system of claim 1 , wherein the shunt is free of a filter.

9 . The system of claim 1 , wherein the access sheath includes an occlusion element.

10 . A system for transcatheter aortic valve treatment, the system comprising:

an access sheath configured to be disposed in a carotid artery, the access sheath having a first lumen and a second lumen formed therein;

wherein the first lumen is configured to have a prosthetic valve delivery system disposed therein;

a first proximal connector coupled to the access sheath, the first proximal connector being in fluid communication with the first lumen;

a second proximal connector coupled to the access sheath, the second proximal connector being in fluid communication with the second lumen; and

a shunt coupled to the second proximal connector, the shunt being configured to provide blood from a secondary blood vessel to the carotid artery.

11 . The system of claim 10 , wherein the first lumen extends from a proximal end of the access sheath to a distal end of the access sheath.

12 . The system of claim 10 , wherein the second lumen extends from a proximal end of the access sheath to a distal port disposed proximally of a distal end of the access sheath.

13 . The system of claim 10 , wherein the access sheath includes a filter.

14 . The system of claim 10 , wherein the access sheath includes an occlusion element.

15 . The system of claim 10 , wherein the shunt comprises an end region disposed within the secondary blood vessel.

16 . The system of claim 15 , wherein the secondary blood vessel includes a femoral artery.

17 . The system of claim 15 , wherein the secondary blood vessel includes a subclavian artery.

18 . The system of claim 15 , wherein the secondary blood vessel includes a contralateral carotid artery.

19 . A system for transcatheter aortic valve treatment, the system comprising:

an access sheath configured to be disposed in a carotid artery, the access sheath having a delivery lumen formed therein that is configured to have a prosthetic valve delivery system disposed therein and a perfusion lumen formed therein;

wherein the access sheath has a proximal end;

a manifold coupled to the proximal end of the access sheath, the manifold including a first connector in fluid communication with the delivery lumen and a second connector in fluid communication with the perfusion lumen; and

a shunt coupled to the second connector, the shunt being configured to provide blood from a secondary blood vessel to the carotid artery.

20 . The system of claim 19 , wherein the delivery lumen extends from the proximal end of the access sheath to a distal end of the access sheath and wherein the perfusion lumen extends from the proximal end of the access sheath to a distal port disposed proximally of the distal end of the access sheath.
