1. A kidney stone removal system, comprising:
(a) a kidney stone removal catheter configured for insertion into a kidney for treatment of kidney stone, the kidney stone removal catheter comprising an irrigation lumen and a vacuum tube lumen, wherein the irrigation lumen communicates with a plurality of irrigation ports and the vacuum lumen is configured and sized for suction of a kidney stone or fragments of a kidney stone; and
(b) a laser guide configured to be removably inserted into the vacuum lumen, wherein the laser guide comprises
(i) a tubular body having distal and proximal opposing open ends and a lumen extending between the opens ends, wherein the lumen is configured to receive a laser device for fragmenting a kidney stone, and
(ii) wings extending from a distal end segment of the tubular body for guiding the distal end segment of the tubular body in the vacuum lumen and creating flow gaps between the tubular body and an inner sidewall of the vacuum lumen such that the flow gaps are sized to allow suction of the kidney stone or fragments of the stone created by the laser device.
