A medical catheter inserted into a body cavity for drainage of fluid. The catheter comprises flexible fibers/filaments that form a plurality of channels for movement of fluid. These fibers/filaments are located around a central inflation device contained within a flexible tubular catheter, composed of two parts. The outer sleeve and inner sleeve form a tubular catheter joined by a flexible connector that interlocks the sleeves during insertion. Once inserted the connection between the two sleeves is released, enabling the outer sleeve to move over top of the inner sleeve revealing fibers/filaments for fluid drainage. An inflatable retention balloon contained within the fibers/filaments secures the catheter in the bladder once inflated. This arrangement allows insertion of non-contaminated fibers/filaments into the body cavity. Insertion of these fibers/filaments creates a more complete drainage of fluid, decreased risk of bacterial infection, reduction of blockage, and improved patient comfort.
