Patent attributes
An extension set may include a tube, which may include a distal end, a proximal end, and an outer surface. The extension set may include a distal connector coupled to the distal end of the tube and/or a proximal connector coupled to the proximal end of the tube. The extension set may include a patency instrument disposed within the tube. The extension set may include a translation handle coupled to the outer surface of the tube. The translation handle may be configured to move along the outer surface of the tube between a proximal position and a distal position to translate the distal end of the patency instrument between a retracted position and an advanced position. In response to the distal end of the patency instrument being in the advanced position, the distal end of the patency instrument may extend beyond the distal end of the tube.
