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.
