Systems and methods are provided for utilizing a laser to break a kidney stones into smaller fragments and/or dust, and removing particles, stone fragments and/or stone dust from a patient. The medical device may include a delivery device including a tube, and an elongate member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the elongate member is configured to move axially relative to the tube and apply suction through the distal end. ## Claims ### Claim 1 A medical device, comprising: a sleeve; a delivery device including a tube; and a member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the lumen of the member is D-shaped with a flat side and a rounded side extending from opposing ends of the flat side, wherein the tube and the member are at least partially positioned within and longitudinally movable relative to the sleeve, wherein the tube and the member are positioned parallel to each other within the sleeve such that at least a portion of a circumferential exterior of the tube abuts a portion of a circumferential exterior of the member, and wherein the member is configured to move axially relative to the tube and apply suction through the distal end. ### Claim 2 (depends on 1) The medical device of claim 1, wherein the proximal end of the member is forked. ### Claim 3 (depends on 1) The medical device of claim 1, wherein the proximal end of the member is connected to a control system. ### Claim 4 (depends on 3) The medical device of claim 3, wherein the control system controls a vacuum source. ### Claim 5 (depends on 1) The medical device of claim 1, wherein the proximal end of the member is in fluid communication with a vacuum source. ### Claim 6 (depends on 1) The medical device of claim 1, wherein the delivery device is one of ureteroscope, sheath, catheter, or endoscope. ### Claim 7 (depends on 1) The medical device of claim 1, further comprising: a laser fiber connected to the tube. ### Claim 8 (depends on 1) The medical device of claim 1, wherein the tube includes an illumination device and an imaging device. ### Claim 9 (depends on 1) The medical device of claim 1, wherein the tube has a first engaging surface, the member has a second engaging surface, and the first engaging surface is complementary of the second engaging surface. ### Claim 10 (depends on 9) The medical device of claim 9, wherein the member is D-shaped with a D-shaped circumferential exterior, with the second engaging surface being flat, and with a curved surface extending from opposite sides of the second engaging surface, wherein the first engaging surface on the tube is flat, and wherein the tube includes a partially circular portion extending from opposite sides of the first engaging surface. ### Claim 11 (depends on 1) The medical device of claim 1, wherein the member is in fluid communication with a fluid source. ### Claim 12 (depends on 1) The medical device of claim 1, wherein the lumen of the member has an inner diameter in the range of 1 mm to 3.5 mm. ### Claim 13 (depends on 1) The medical device of claim 1, wherein the member is at least partially controlled by a control system and the tube is at least partially controlled by a handle, wherein the member is coupled to a suction source, and wherein the member is longitudinally movable relative to the tube and is configured to extend distally beyond the tube to apply suction to an object at a first position and retract proximally to bring the object to a second position closer to a distal end of the tube. ### Claim 14 A medical device, comprising: a sleeve; a delivery device including a tube having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the tube includes a first flat portion; and a member having a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the member includes a second flat portion, and wherein the lumen of the member includes a D-shaped cross-section with a flat side and a rounded side extending from opposing ends of the flat side, wherein the tube and the member are positioned adjacent to each other at least partially within the sleeve such that the first flat portion of the tube abuts the second flat portion of the member, and wherein the member is movable from at least a first position where the distal end of the member is aligned with the distal end of the tube to a second position where the distal end of the member is distally beyond the distal end of the tube. ### Claim 15 (depends on 14) The medical device of claim 14, wherein the member is D-shaped with a circumferential exterior having a D-shaped cross-section with a curved surface extending from opposite sides of the second flat portion, wherein the tube includes a partially circular portion extending from opposite sides of the first flat portion, and wherein the lumen through the tube is semicircular. ### Claim 16 (depends on 15) The medical device of claim 15, further including a laser element positioned within the lumen of the tube, wherein the laser element is longitudinally moveable within the lumen of the tube to extend distally beyond the distal end of the tube. ### Claim 17 A medical device, comprising: a sleeve; a delivery device including a tube at least partially positioned within the sleeve and having a distal end, a proximal end, and an lumen extending between the proximal end and the distal end; a member at least partially positioned within the sleeve and positioned adjacent to the tube, wherein the member includes a distal end, a proximal end, and a lumen extending between the proximal end and the distal end, wherein the lumen of the member includes a D-shaped cross-section with a flat side and a rounded side extending from opposing ends of the flat side; and a laser element movably positioned within the lumen of the tube, wherein the tube and the member are positioned adjacent to each other within the sleeve, wherein the tube and the member are longitudinally movable relative to the sleeve, and wherein the laser element is extendable distally beyond the distal end of the tube. ### Claim 18 (depends on 17) The medical device of claim 17, wherein the tube includes a first flat portion, wherein the member includes a second flat portion, and wherein the first flat portion of the tube abuts the second flat portion of the member. ### Claim 19 (depends on 18) The medical device of claim 18, wherein the member is movable from at least a first position where the distal end of the member is aligned with the distal end of the tube to a second position where the distal end of the member is distally beyond the distal end of the tube.
