The present invention is a medical device for anchoring itself and other medical devices while channeling blood flow through the center of a vessel proximal to the device's target area to minimize debris and the pressure necessary to move blood proximal to the device of the present invention. It also provides superior recoil reduction capabilities. Disclosed is a bulging torus or doughnut-shaped balloon medical device that may be inflated and deflated by increasing and decreasing pressure within the balloon, having two passages therethrough, dimensioned for blood flow and a delivery device. A method using the device is also disclosed.
