More Information
Summary: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.
