Fluid management system with integrated laser fiber cooling

A medical system, comprising:

• an endoscope comprising:
• an elongate shaft configured to access a treatment site within a patient;
• and
• a handle coupled to a proximal end of the elongate shaft;
• a laser device including an elongate tubular member configured for insertion through a working lumen of the elongate shaft of the endoscope, the elongate tubular member including a cooling channel and a laser fiber extending distally within the cooling channel;
• and
• a fluid management system comprising:
• an inflow pump configured to pump fluid from a first fluid supply source through the elongate shaft to the treatment site;
• a cooling pump configured to pump fluid from a second fluid supply source through the cooling channel;
• and
• a controller configured to control the inflow pump and the cooling pump;
• wherein the laser device includes a laser controller in electronic communication with the controller of the fluid management system.
