摘要： The present disclosure relates to medical devices that that include the following: a flexible elongate tube having a proximal end and a distal end configured to be directed toward an opening of a body lumen; a first lumen extending from the distal end of the tube proximally along the tube and having a fluid connection for a fluid source at its proximal end; a second lumen extending from the distal end of the tube proximally along the tube, the second lumen configured to accept a guidewire extending along the second lumen; and a wire filament extending along the elongate tube, a distal end of the filament connected to the distal end of the elongate tube, a proximal portion of the wire extending at least partially along the elongate tube, and a distal portion of the wire extending external to the elongate tube.
