Patent number: 11759613Abstract: 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.Type: GrantFiled: November 9, 2020Date of Patent: September 19, 2023Assignee: Silk Road Medical, Inc.Inventors: Stewart M. Kume, Michi E. Garrison, Michael P. Wallace, Herbert Mendoza, Marlon Moreno
