Abstract
A drainage system including a balloon catheter comprising a tubular shaft having proximal and distal ends, an inflatable sleeve surrounding the shaft adjacent the distal end thereof and upon inflation retaining the catheter in position by formation of an enlarged balloon surrounding the shaft, a first opening adjacent the distal end of the shaft through which body fluids may pass into a drainage channel which extends from the first opening through the length of the shaft, and a second opening spaced from the first opening through which the fluids may pass from the channel. A longitudinally extending portion of the channel is formed from a porous material which is pervious to air and impervious to body fluids and which is not-wettable by body fluids, and the inflatable sleeve comprises an elastomeric material other than the porous material.
