1. A system for use in a removal procedure of a biological object from a urinary tract, the system comprising:
a catheter body comprising a proximal end and a distal end configured to be inserted into the urinary tract, the catheter body comprising one or more openings at least partially facing an axial direction of the catheter body, wherein the one or more openings are configured to receive at least a portion of the biological object;
an evacuation lumen positioned at least partially within the catheter body, wherein the evacuation lumen is in fluid communication with the one or more openings and wherein the evacuation lumen is configured to receive an ablation device; and
a supply lumen positioned entirely within the catheter body and configured to transport a liquid from a liquid source to the distal end of the catheter body, the supply lumen configured to eject the liquid as a liquid jet outside the supply lumen and create a vacuum at the one or more openings via a Venturi effect,
wherein the vacuum created via the Venturi effect is configured to attract the biological object toward the one or more openings and the system is configured to remove a plurality of fragments of the biological object from the urinary tract through the evacuation lumen toward the proximal end of the catheter body with a regulated fluid flow.
