Abstract
A perfusion balloon catheter which permits blood flow through the balloon even when the balloon is inflated. The balloon catheter comprises a thin-walled, collapsible and inflatable tube that has a proximal, generally straight portion, and a distal, helically coiled portion that is generally cylindrically shaped and defines an open lumen therethrough. The successive turns of the coil are secured to one another to maintain the balloon's configuration when inflated. The furled balloon catheter can be inserted to the desired location and then inflated. Because the helically coiled portion defines a relatively large open lumen, blood flow through the balloon can continue even as the inflated balloon remains in place, facilitating extended inflation periods.
