Abstract (en)
[origin: WO2016118948A1] An indwelling device for insertion in a biological tubular structure comprising an elongated device having a body and opposing ends. The body has a bending stiffness transverse to a longitudinal axis that is greater than a stiffness of the biological tubular structure. An atraumatic tip member, having a proximal end and a distal end, extends from the end of the elongated device. The proximal end has a first bending stiffness transverse to a longitudinal axis and the distal end has a second bending stiffness transverse to the longitudinal axis, wherein the second stiffness being less than the first stiffness.
