Methods and devices for transcarotid access
First Claim
1. An arterial access sheath for introducing an interventional device into an artery, comprising:
- an elongated body sized and shaped to be transcervically introduced into a common carotid artery at an access location in the neck;
an internal lumen in the elongated body having a proximal opening in a proximal region of the elongated body and a distal opening in a distal region of the elongated body, the internal lumen providing a passageway for introducing an interventional device into the common carotid artery when the elongated body is positioned in the common carotid artery;
wherein the elongated body has a proximal section and a distal most section that is more flexible than the proximal section, and wherein a ratio of an entire length of the distal most section to an overall length of the sheath body is one tenth to one half the overall length of the sheath body, and wherein the overall length of the elongated body is 20 cm to 30 cm.

Abstract
Disclosed is an arterial access sheath for introducing an interventional device into an artery. The arterial access sheath includes an elongated body sized and shaped to be transcervically introduced into a common carotid artery at an access location in the neck and an internal lumen in the elongated body having a proximal opening in a proximal region of the elongated body and a distal opening in a distal region of the elongated body. The internal lumen provides a passageway for introducing an interventional device into the common carotid artery when the elongated body is positioned in the common carotid artery. The elongated body has a proximal section and a distalmost section that is more flexible than the proximal section. A ratio of an entire length of the distalmost section to an overall length of the sheath body is one tenth to one half the overall length of the sheath body.
