Abstract
A catheter that has a catheter tube everting inside-out during the process of catheterization. The catheter tube has a plurality of longitudinal protrusions extending from the first end of the catheter tube through at least a portion of the catheter tube, and forming an angle of 0 degrees to 45 degrees with respect to the longitudinal axis of the catheter tube and facing radially inwards, and provides for dilating a circumference of the catheter tube upon everting the catheter tube inside-out from the first end of the catheter tube.
Claims12
A catheter tube (10) comprising
- a first open end (11) and a second open end (12),
- four to twelve longitudinal protrusions (14), the four to twelve longitudinal protrusions (14) extending from the first end (11) of the catheter tube (10) through the full length of the catheter tube (10), and forming an angle of 0 degrees to 45 degrees with respect to the longitudinal axis of the catheter tube (10) and facing radially inwards, wherein the four to twelve longitudinal protrusions are configured to provide an axial reinforcement of the catheter tube, and
- one or more dilatable protrusions (34) for dilating a circumference of the catheter tube (10) upon everting the catheter tube (10) inside-out from the first end (11) of the catheter tube (10).
