Abstract

A retrieval device is provided for retrieving stones, calculi, and other objects from a body. The device allows for a retrieval basket to be articulated and extended simultaneously. The device also allows for the basket to be articulated and retracted simultaneously.

Claims

1. A medical device, the device comprising:

a body;

an articulator movably connected to the body;

at least a first and a second wire having distal ends;

the first and second wire in communication with the articulator;

a tool disposed at the distal end of the first and second wire, wherein the articulator is capable of moving the tool outside the longitudinal plane; and

wherein the tool is capable of being extended and retracted in a longitudinal plane simultaneously with movement outside the longitudinal plane.

2. The device according to claim 1 wherein the tool is a basket, a grasping device, or a sampling device.

3. The device according to claim 1 wherein the articulator further comprises two finger grooves or two finger-holes.

4. The device according to claim 1 wherein the articulator is movably connected to the body via a pivot pin.

5. The device according to claim 1 wherein the articulator further comprises at least a first and a second pivot pin, wherein at least one wire is in communication with the first pivot pin or the second pivot pin.

6. The device according to claim 1 wherein the articulator further comprises at least a first and a second pivot pin, wherein the first wire and the second wire are in communication with the first pivot pin and the second pivot pin.

7. The device according to claim 1 wherein the articulator further comprises a first pivot pin, a second pivot pint, and a third pivot pin;

wherein the first wire is connected to the first pivot pin and the second pivot pin, and the second wire is connected to the third pivot pin.

8. The device according to claim 1 further comprising a wire connection point;

wherein the distal ends of the first wire and the second wire are connected via a soldered point, a loop, or a connection disk.

9. The device according to claim 1 wherein the body further comprises an axis where along the articulator can move in a proximal and a distal direction.

10. The device according to claim 1 wherein the first and second wires further comprise wire fibers and the wire fibers are in a net-configuration.

11. A medical device, the device comprising:

a body;

a slide assembly slideably attached to the body;

an articulator rotateably attached to the body, wherein the articulator is in communication with the slide assembly;

a first wire and a second wire having distal ends, wherein the first wire and the second wire are attached to the articulator;

a tool disposed at the distal ends of the first and second wires, wherein the articulator is configured to move the tool outside a longitudinal plane; and

wherein the slide assembly is configured to extend and retract the first and second wires.

12. The device according to claim 11, wherein the articulator further comprises:

an articulator drum that is rotateably connected to the slide assembly; and

a first wire pivot and a second wire pivot, wherein the first wire pivot and the second wire pivot are threadily attached to the articulator drum and the first wire pivot is fixedly attached to the first wire, and the second wire pivot is fixedly attached to the second wire.

13. The device according to claim 12, wherein the articulator further comprises a lever, wheel, or gear set that is configured to rotate the articulator drum.

14. The device according to claim 11, wherein the slide assembly further comprises a slide that is configured to extend and retract the first wire and the second wire.

15. The device according to claim 11, wherein the slide assembly and the articulator can be engaged simultaneously.

16. The device according to claim 11, wherein the tool is a basket, a grasping device, or a sampling device.

17. A retrieval device, the device comprising:

a tool formed by at least one wire; and

means for extending or retracting the tool and simultaneously articulating the tool in a plane outside a longitudinal plane.

18. The device according to claim 17, wherein the means for extending the tool comprises a slide assembly.

19. The device according to claim 17, wherein the tool is a basket, a grasping device, or a sampling device.

20. The device according to claim 17, wherein the means for articulating the tool comprises an articulator having at least two pivot pins wherein the at least one wire of the tool is attached to at least one of the two pivot pins.

21. The device according to claim 17, wherein the at least one wire further comprises a first and a second wire;

wherein the tool is a basket, a grasping device, or a sampling device;

wherein the tool is formed by the first and second-wire; and

wherein the means for articulating the tool comprises a first wire pivot and a second wire pivot, wherein the first wire pivot and the second wire pivot are threadily attached to an articulator drum, the first wire pivot is fixedly attached to the first wire, and the second wire pivot is fixedly attached to the second wire.

22. A method for retrieving an object, the method comprising:

inserting a device for removing an object into a patient;

extending a tool of the device out to the object;

articulating the tool to encapsulate the object; and

retracting the tool to retrieve the object, wherein the extending and the articulating are capable of being performed simultaneously or the articulating and the retracting are capable of being performed simultaneously.

23. The method of according to claim 22, wherein the tool is a basket, a grasping device, or a sampling device.
