Abstract
A perfusion catheter for insertion into a body conduit, especially an artery. The catheter comprises a shaft (5) having at least two lumens for delivery of fluid inflation medias 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 (1) 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). An internal chamber (31) is formed inside the array (1) by the movement of a wall (30) over the axis of the catheter whereby to enable a substantial increase of inflation forces against the body conduit in which the catheter is disposed.
