Catheters are provided which have a high capacity of axial (pushability) and rotational (torquability) movement with relative maximum flexibility and which, at the same time have the ability to adapt to at least partial variations of diameter under the thrust of other catheters or dilators travelling though the lumen or so as to flatten itself at least partially to travel through the lumen of other catheters, such as for example feed catheters. |
