Abstract

A translumenal access device including a cannula defining a first lumen. The cannula may be sized for insertion into a working channel of a flexible endoscope. The device includes a rotatable rotary needle positioned within the cannula. The rotary needle may define a lumen that houses a stylet. The distal end of the rotary needle may define a distal circular opening with a cutting edge. The rotary needle may be used to slice through tissue during a surgical procedure.

Claims

1. A translumenal access device, comprising:

a flexible cannula defining a first lumen, the cannula sized for insertion into a working channel of a endoscope; and

a flexible rotatable rotary needle positioned within the cannula, the tubular needle defining a second lumen, the rotary needle comprising a distal end and a proximal end, the distal end of the rotary needle defining a distal opening comprising a cutting edge.

2. The device of claim 1, comprising a flexible stylet slidably disposed within the rotary needle, wherein the flexible stylet is selectably movable between a first position and second position.

3. The device of claim 2, wherein the flexible stylet is biased with a biasing member.

4. The device of claim 1, wherein the cutting edge is located on the periphery of the distal circular opening.

5. The device of claim 1, wherein the rotary needle position with respect to the cannula is selectable.

6. The device of claim 5, further comprising a handle assembly, wherein the rotary needle position is selected with controls on the handle assembly.

7. The device of claim 6, wherein the handle assembly comprises a wheel coupled to the rotary needle.

8. The device of claim 7, wherein the handle assembly comprises a movable distal portion.

9. The device of claim 8, wherein movement of the moveable distal portion moves the cannula with respect to the rotary needle.

10. A translumenal access device, comprising:

a handle assembly comprising a rotatable portion;

a cannula defining a first lumen, the cannula sized for insertion into a working channel of an endoscope, the cannula coupled to the rotatable portion;

a rotatable rotary needle positioned within the cannula, the tubular needle defining a second lumen, the rotary needle comprising a distal end and a proximal end, wherein the outer diameter of the rotary needle is less than about 0.050 inches; and

a stylet selectively positionable within the rotary needle, wherein the distal end of the rotary needle defines a distal circular opening.

11. The device of claim 10, wherein rotation of the rotatable portion in a first direction advances the distal end of the rotary needle from the cannula and rotation of the rotatable portion in a second direction retracts the distal end of the rotary needle into the cannula.

12. The device of claim 10, wherein the distal circular opening comprises a cutting edge.

13. The device of claim 10, comprising a wheel located in the handle assembly for rotating the rotary needle.

14. The device of claim 13, wherein the stylet is biased with a biasing member.

15. A method comprising:

inserting an endoscope into a lumen of a patient;

inserting a surgical instrument into the lumen of the patient through a working channel of the endoscope;

placing a cannula near a portion of tissue to be penetrated;

advancing a rotary needle distally from the cannula;

rotating the rotary needle and penetrating the tissue with a distal portion of the rotary needle;

inserting the surgical instrument through the penetration in the tissue.

16. The method of claim 15, comprising

inserting an inflatable member into the penetration inflating the inflatable member;

placing a distal end of the endoscope at a proximal end of the inflatable member;

forcing the inflatable member and the distal end of the endoscope through the penetration;

deflating the inflatable member; and

removing the surgical instrument from the working channel of the endoscope.

17. The method of claim 15, wherein the surgical instrument comprises a handle assembly, wherein the rotary needle is advanced distally from the cannula by rotating a portion of the handle assembly.

18. The method of claim 17, wherein the handle assembly comprises a wheel, wherein rotation of the wheel rotates the rotary needle.

19. The method of claim 15, wherein a circular cutting edge is located on the periphery of the distal portion of the rotary needle.

20. The method of claim 15, comprising placing a distal end of the cannula against the portion of tissue to be penetrated.
