Abstract

Devices, systems, and methods are provided for breaking a kidney stone(s) into smaller particles, fragments, and/or stone dust; and removing the same from a patient. The medical device may include a tube having a distal end, a proximal end, a port located proximal of the distal end, and a length of the tube extending between the proximal end and the distal end. A first portion of the tube may be proximal of the port and have a first cross-sectional area, while a second portion of the tube may be distal of the port and have a second cross-sectional area smaller than the first cross-sectional area. A first lumen may extend from the proximal end to the distal end of the tube. A second lumen may in communication with the port to fluidly connect the proximal end of the tube with the port.

First claim

What is claimed is:

1 . A medical device, comprising:
a tube having a distal end, a proximal end, a port located proximal of the distal end, and a length of the tube extending between the proximal end and the distal end, wherein a first portion of the tube is proximal of the port and has a first cross-sectional area and a second portion of the tube is distal of the port and has a second cross-sectional area smaller than the first cross-sectional area; a first lumen extending from the proximal end to the distal end of the tube; and a second lumen in communication with the port and fluidly connecting the proximal end of the tube with the port.

2 . The medical device of claim 1 , wherein the port is distal to the proximal end by a distance of approximately half to approximately three-quarters the length of the tube.

3 . The medical device of claim 1 , further comprising:
a laser fiber disposed within the first lumen.

4 . The medical device of claim 1 , further comprising:
a fluid supply assembly connected to the first lumen.

5 . The medical device of claim 1 , wherein the first lumen is configured to simultaneously connect to a fluid supply apparatus and a laser control.

6 . The medical device of claim 5 , wherein a laser extends from the laser control into the first lumen and to the distal end.

7 . The medical device of claim 1 , further comprising:
a vacuum source connected to the second lumen.

8 . The medical device of claim 1 , wherein the port is angled relative to a longitudinal axis of the second lumen.

9 . The medical device of claim 1 , further comprising:
an illumination device extending through the tube.

10 . The medical device of claim 1 , further comprising:
an imaging device extending through the tube.

11 . The medical device of claim 1 , wherein the first cross-sectional area is approximately 3 mm to approximately 5 mm.

12 . The medical device of claim 1 , wherein the second cross-sectional area is approximately 2 mm to approximately 5 mm.

13 . The medical device of claim 1 , wherein the port is substantially crescent-shaped.

14 . The medical device of claim 1 , wherein the port is located approximately 5 cm to approximately 15 cm from the distal end.

15 . The medical device of claim 1 , wherein the second lumen terminates at the port.

16 . A method of operating a medical device, comprising:
positioning a distal end of a medical device at a target area, the medical device including a first lumen and a second lumen, wherein the second lumen is in fluid communication with a port and the port is proximal of the distal end of the medical device; supplying fluid through the first lumen; and applying suction through the second lumen.

17 . The method of claim 16 , wherein the port is at least 10 cm from the distal end of the medical device.

18 . The method of claim 16 , wherein the target area is within a patient's kidney and the port is positioned within the patient's ureter.

19 . A medical device, comprising:
a tube having a distal end, a proximal end, and a port located at least approximately 10 cm from the distal end; a first lumen in communication with the distal end and fluidly connecting the distal end with a fluid supply assembly; and a second lumen in communication with the port and fluidly connecting a vacuum source with the port.

20 . The medical device of claim 19 , wherein the port is at least partially distal-facing.
