Abstract:
A catheter assembly comprising:an elongate flexible tubular shaft having a proximal end and a distal end, with a radial wall defining a lumen extending longitudinally between the proximal end and the distal end; a polymeric tubular sleeve placed onto the tubular shaft so as to cover at least a proximal portion of the outer surface of the radial wall of the tubular shaft, said polymeric tubular sleeve having a proximal end extending proximally beyond the proximal end of the tubular shaft and a distal end, with a radial wall defining a lumen extending longitudinally between the proximal end and the distal end, said sleeve being open at the distal and proximal ends, the sleeve being fused to the tubular shaft; and a hub of a polymeric material molded over and fused to the polymeric sleeve at the proximal end of the tubular shaft, said hub defining a lumen therein, the hub lumen having an inner wall, said hub being disposed around the tubular shaft and covering at least part of the polymeric sleeve such that the distal end of the polymeric sleeve extends distally of the hub.
