Abstract

Provided herein are devices, systems, and methods for treating a kidney stone. In particular, provided herein are suction devices, laser systems, and related methods for use in treating a kidney stone.

Claims (11)

1. A device, comprising:

suction tubing having or configured to have a bend of greater than 90 degrees in a distal portion of the suction tubing; and

a suction cone comprising an opening at a proximal end, wherein said proximal opening has a diameter of 0.5 to 1.5 mm and comprises a rounded proximal region adjacent said proximal opening, wherein said proximal region has a smaller outer diameter than said suction cone, and wherein said opening is operably linked to the suction tubing and a suction cone body comprising a distal opening, wherein said distal opening has a larger diameter than said proximal opening, and wherein said distal opening has a diameter of 4-12 mm,

wherein said suction cone comprises a wire wrapped around said suction cone that controls deployment of said wire between a collapsed configuration and an expanded configuration, and

wherein said suction tube is deployable between a collapsed configuration and an expanded configuration and further comprises one or more wires configured for deploying the suction tubing into the expanded configuration, and wherein when said device is in said expanded configuration, said suction tubing is oriented in a curved configuration.

2. The device of claim 1 , wherein said suction cone is constructed of a flexible material selected from the group consisting of a polymer, nickel titanium, and a wire mesh.

3. The device of claim 1 , wherein said suction tubing extends from said proximal opening of said suction cone and makes a turn greater than 90 degrees when said suction cone is in a deployed configuration.

4. A system, comprising:

the device of claim 1 ; and

a suction pump.

5. The system of claim 4 , wherein said system further comprises one or more of a ureteroscope and a laser fiber.
