Abstract
A perfusion catheter for insertion into a body conduit, especially an artery. The catheter comprises a shaft (5) having at least one lumen (7) for delivery of a fluid inflation media and an array (1) formed of a plurality of radially disposed inflatable balloons (3) disposed in a cylindrical array around the shaft (5), each of the balloons (3) sharing a common wall (3a) with adjacent balloons (3). The balloons (3) are inflated by an array of channels (11) and separated from each other by a web (19). There is at least one opening (17) between two adjacent channels (11) to allow the flow of fluids into the array (1).
