Segmented arch fulcrum support catheter and method of use

Abstract

The present disclosure teaches a medical device and method of use, employing a tube which is composed of segments and bends capable being configured into unique shape that allows said device to use the lesser (inferior) curve of aortic Arch and other vessel structures as as fulcrums of support for a guide catheter, for subsequent prevention of recoil and displacement thereof, while delivering additional catheters or devices into the distal branches of the great vessels. A method for using same.
