Abstract: A neurovascular catheter can have an elongate flexible tubular body. The tubular body can have a proximal end, an inclined distal end, and a side wall that defines a central lumen. The neurovascular catheter can further have a distal leading tip on a first side of the inclined distal end. The neurovascular catheter can further have a preset curve in a distal zone of the tubular body such that wherein the distal leading tip lies on a concave side of the curve.

Abstract: A neurovascular catheter has enhanced tensile strength to resist distal tip detachment during proximal retraction past an obstruction. The catheter includes an elongated flexible tubular body, having a proximal end, a distal end and a side wall defining a central lumen. A radiopaque marker is provided adjacent to the distal end. The tensile support extends axially inside the side wall and is attached to the radiopaque marker, to tether the marker to the catheter body. In one implementation, the tensile support may at least partially wrap around the marker. The marker may have a tubular sidewall with a feature to increase compressibility, such as at least one compression gap in a proximal portion of the side wall.
