Claims. (01. 128-349) 1 The present invention relates to surgical appliances, and has particular reference to a novel construction for a catheter.
The principal object of the invention is to provide a catheter construction of the inflatable 5 channel. The cloth inserted strips are of standballoon type which has no distal tip or projection. ard type, manufactured by dipping cloth into Another object of the invention is to provide latex or rubber solution to encase the cloth with a balloon catheter construction having an axial rubber.
