## Abstract

The present disclosure is directed to a medical device. Systems and methods are provided for utilizing a laser to break 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 method of operating a medical device, the method comprising:
positioning a distal end of a member of the medical device distal to a distal end of a tube of the medical device;
applying suction through a lumen of the member to couple an object to the distal end of the member; and
moving the distal end of the member to move the object coupled to the distal end of the member proximally toward the distal end of the tube.

### Claim 2 (depends on 1)

The method of claim 1, further comprising:
disposing a laser fiber within the tube; and
initiating a laser to deliver energy through the laser fiber.

### Claim 3 (depends on 2)

The method of claim 2, wherein initiating the laser includes delivering laser energy toward the object.

### Claim 4 (depends on 3)

The method of claim 3, further comprising applying suction through one or more of the lumen of the member or a lumen of the tube.

### Claim 5 (depends on 1)

The method of claim 1, wherein, prior to positioning the distal end of the member distal to the distal end of the tube of the medical device, the method further comprises:
positioning the distal end of the member proximal to the distal end of the tube of the medical device; and
supplying dye through the lumen of the member to the distal end of the member.

### Claim 6 (depends on 1)

The method of claim 1, wherein the tube and the member are adjacent to each other within a sleeve, such that a portion of a circumferential exterior of the tube abuts a portion of a circumferential exterior of the member.

### Claim 7 (depends on 1)

The method of claim 1, wherein the lumen of the member is D-shaped with a flat side and a rounded side extending from opposing sides of the flat side.

### Claim 8 (depends on 6)

The method of claim 6, wherein the tube includes a first flat engaging surface and a partially circular portion extending from opposite sides of the first flat engaging surface, and wherein the member includes a second flat engaging surface configured to abut the first flat engaging surface.

### Claim 9 (depends on 1)

The method of claim 1, wherein the object is a kidney stone.

### Claim 10

A method of operating a medical system, the method comprising:
positioning a distal end the medical system at a target area, wherein the medical system includes a member, a tube, and a sleeve, wherein the member and the tube are movably positioned within the sleeve;
applying suction through a lumen of the member to couple an object to the distal end of the member;
moving the distal end of the member proximally to move the object coupled to the distal end of the member;
disposing a laser fiber within a lumen of the tube; and
initiating the laser fiber to at least partially break up the object.

### Claim 11 (depends on 10)

The method of claim 10, wherein the member and the tube are positioned adjacent 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.

### Claim 12 (depends on 10)

The method of claim 10, further comprising, before applying the suction through the lumen of the member, extending the member distally of a distal end of the tube.

### Claim 13 (depends on 12)

The method of claim 12, further comprising applying additional suction through the lumen of the member to remove one or more portions of the object from the target area.

### Claim 14 (depends on 10)

The method of claim 10, wherein the lumen of the member is D-shaped with a flat side and a rounded side extending from opposing sides of the flat side.

### Claim 15 (depends on 14)

The method of claim 14, wherein the tube includes a first flat engaging surface and a partially circular portion extending from opposite sides of the first flat engaging surface, and wherein the member includes a second flat engaging surface configured to abut the first flat engaging surface.

### Claim 16 (depends on 10)

The method of claim 10, wherein the object is a kidney stone.

### Claim 17

A method of operating a medical system, the method comprising:
positioning a distal end the medical system at a target area, wherein the medical system includes a member, a tube, and a sleeve, wherein the member and the tube are movably positioned within the sleeve;
extending the member distally of a distal end of the tube;
applying suction through a lumen of the member to couple an object to the distal end of the member; and
moving the distal end of the member proximally to move the object coupled to the distal end of the member.

### Claim 18 (depends on 17)

The method of claim 17, further comprising:
disposing a laser fiber within a lumen of the tube; and
initiating the laser fiber to at least partially break up the object.

### Claim 19 (depends on 17)

The method of claim 17, wherein the tube includes a first flat engaging surface and a partially circular portion extending from opposite sides of the first flat engaging surface, and wherein the member includes a second flat engaging surface configured to abut the first flat engaging surface.

### Claim 20 (depends on 17)

The method of claim 17, wherein, prior to positioning the distal end of the member of the medical system at the target area, the method further comprises:
positioning the distal end of the member proximal to the target area; and
supplying dye through the lumen of the member to the distal end of the member.
