Medical device for stone management

A medical device for stone management, comprising:

• a multi-lumen catheter comprising a proximal end, a distal end, and an inner lumen and an outer lumen at least partially surrounding the first lumen;
• a handle assembly interconnected with the proximal end of the catheter, the handle assembly comprising a body defining an interior cavity, a first section and a second section;
• an interior passageway disposed within the interior cavity;
• the interior passageway in fluid communication with the outer lumen of the catheter and having a first end and a second end;
• a valve assembly positioned within the interior passageway, the valve assembly moveable between a first position and a second position;
• an actuator assembly engaged with the valve assembly;
• and
• a vacuum port positioned on the second section of the handle assembly and in fluid communication with the interior passageway;
• wherein the second section of the handle assembly forms an angle with respect to the first section of the handle assembly,
• wherein the actuator allows for incremental movement of the valve assembly between the first position to the second position, and
• wherein the second end of the interior passageway is adjacent to the vacuum port.
