Problems solved by technology

Conventional interventional sheaths and sheath dilators are not flexible enough to position safely at the site
[0012] Also, if the working area is close to the access site, radiation exposure can be a problem for the operator's hands for procedures utilizing the transcarotid access site

Embodiment Construction

[0032] Methods, systems and devices for accessing and treating blood vessels via a transcarotid access point in the carotid region are disclosed.

[0033] figure 1 A first embodiment of a transcarotid initial access system 100 of a device for establishing initial access to a carotid artery to enable introduction of a guidewire into the carotid artery is shown. Initial access to the carotid artery occurs at an access site located in the patient's neck, such as in the patient's carotid artery region. Transcarotid Initial Access The device of system 100 is particularly suited for direct access to the carotid artery through the wall of the common carotid artery.

[0034] Such as figure 1 As shown, initial transcarotid access system 100 includes access needle 120 , access guide wire 140 and micropuncture cannula 160 . Access needle 120, access guide wire 140, and micropuncture cannula 160 are all adapted to be introduced into the carotid artery via carotid puncture, as further...

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.
