  • ENHANCED FLEXIBILITY NEUROVASCULAR CATHETER
    Publication number: 20230226318
    Abstract: An enhanced flexibility catheter is provided, such as for distal neurovascular access or aspiration. The catheter includes an elongate flexible body, having a proximal end, a distal end, and a side wall defining a central lumen. The side wall is formed from a plurality of adjacent tubular segments. At least one segment has a first end face inclined at a non normal angle to a longitudinal axis of the catheter. An adjacent segment has a second end face inclined at a complementary angle to form an inclined junction at the transition between the two segments. The transition serves to provide superior bending characteristics along the length of the catheter shaft.
