Abstract:
1. A process of manufacturing and packaging a catheter comprising: manufacturing a catheter body comprised of a catheter layer, a reinforcement layer and a resin layer, the catheter layer being made of a composition that includes both ETFE and PTFE in a mass ratio of 99:1 to 45:55, the catheter body being tubular in form and possessing a wall thickness of 0.02 mm to 0.5 mm, the catheter body possessing a proximal end; forming the reinforcement layer so the reinforcement layer is positioned in overlying relation to the catheter layer; forming the resin layer outside the reinforcement layer so that the reinforcement layer is positioned between the catheter layer and the resin layer, the resin layer being comprised of a resin composition different from the composition forming the catheter layer; mounting a hub to the proximal end of the catheter body to form a catheter; sealing the catheter with a packaging material which exhibits barrier properties to bacteria; and electron-beam sterilizing the catheter sealed with the packaging material through use of electron-beam irradiation.
