Abstract
A reinforced catheter having a multi-layered structure suitable for medical uses comprising an inner liner, a braided reinforced layer adjacent to the inner liner, a first resin adjacent to the braided layer, and a harder second resin overlaying the first resin; wherein, the first resin and second resin taper inversely to one another along the length of the catheter, thereby forming a co-tapered soft tip that reduces body trauma.
