Abstract

Devices are provided herein for translumenal access to a treatment site within a body cavity. In general, the devices include an elongate sleeve configured to provide access to a treatment site wherein various portions of the sleeve are associated with an anti-microbial agent. Additionally, the anti-microbial agent(s) can be disposed within a housing and/or inner lumen of the sleeve such that surgical instruments passing therethrough can be sterilized en route to and/or being withdrawn from the treatment site. Additionally, various methods are also provided herein for maintaining the sterility of a treatment site.

Claims

1. A translumenal trocar device, comprising:

a flexible elongate sleeve having an inner lumen extending between proximal and distal ends thereof and forming a working channel for receiving and guiding instruments to a surgical site; and

an anti-microbial agent located within the inner lumen and effective to sterilize instruments passed through the lumen to maintain a sterile surgical site.

2. The device of claim 1, wherein the elongate sleeve includes a housing having a seal formed therein and adapted to form a seal around instruments passed through the housing and the elongate sleeve.

3. The device of claim 2, wherein the anti-microbial agent comprises a coating located on the seal.

4. The device of claim 2, wherein the anti-microbial agent comprises a solution delivered to the seal.

5. The device of claim 2, wherein the seal is formed from a material containing the anti-microbial agent.

6. The device of claim 1, wherein the anti-microbial agent comprises an anti-microbial coating disposed on at least a portion of the elongate sleeve.

7. The device of claim 1, further comprising a sponge disposed within the inner lumen of the elongate sleeve and containing the anti-microbial agent.

8. The device of claim 7, wherein the anti-microbial agent comprises a solution that is delivered to the sponge.

9. The device of claim 1, wherein the anti-microbial agent comprises an anti-microbial solution adapted to be transferred to an instrument passed through the lumen.

10. The device of claim 9, further comprising a reservoir coupled to the housing and adapted to deliver the anti-microbial solution to the elongate sleeve for transfer onto an instrument passed through the lumen.

11. The device of claim 1, further comprising an obturator removably disposable through the lumen in the elongate sleeve and having a distal end adapted to penetrate through tissue.

12. The device of claim 11, wherein the obturator includes an anti-microbial agent.

13. The device of claim 11, wherein the anti-microbial agent comprises a coating disposed on at least a portion of the obturator.

14. A translumenal trocar device, comprising:

a flexible trocar sleeve having an elongate tube with a housing formed on a proximal end thereof, the trocar sleeve having a lumen extending therethrough;

an obturator disposed through the lumen in the trocar sleeve and having a distal tip that extends distally beyond a distal end of the trocar sleeve such that the distal tip is adapted to guide the obturator and trocar sleeve through tissue; and

an anti-microbial agent associated with at least one of the trocar sleeve and the obturator.

15. The device of claim 14, wherein the anti-microbial agent is located within the trocar sleeve such that it is adapted to sterilize instruments passed through the lumen of the trocar sleeve.

16. The device of claim 14, further comprising a seal disposed within the housing of the flexible trocar sleeve.

17. The device of claim 16, wherein the anti-microbial agent is located on the seal.

18. The device of claim 14, wherein the anti-microbial agent comprises a coating disposed on at least a portion of at least one of the trocar sleeve and the obturator.

19. The device of claim 14, wherein the anti-microbial agent comprises a solution delivered to at least a portion of at least one of the trocar sleeve and the obturator.

20. The device of claim 14, wherein at least a portion of at least one of the trocar sleeve and the obturator is formed from a material containing the anti-microbial agent.

21. A method for maintaining a sterile surgical site, comprising:

positioning a flexible tube through a body lumen; and

inserting an instrument through the flexible tube to position a distal end of the instrument adjacent to a treatment site, the flexible tube including an anti-microbial agent that sterilizes the instrument as it is passed through the flexible tube.

22. The method of claim 21, wherein positioning the flexible tube comprises positioning a distal end of the tube adjacent to tissue to be penetrated while a proximal end of the tube remains outside of the patient'"'"'s body.

23. The method of claim 22, further comprising penetrating the distal end of the instrument through the tissue located adjacent to the distal end of the tube to position the distal end of the instrument within a body cavity.

24. The method of claim 23, further comprising removing the instrument from the body cavity and the flexible tube, the anti-microbial agent sterilizing the instrument as it is removed, and introducing a second instrument through the flexible tube, the anti-microbial agent sterilizing the second instrument as it passed through the flexible tube.

25. The method of claim 21, wherein the anti-microbial agent is disposed on a seal contained within a housing formed on a proximal end of the flexible tube, and wherein the seal forms a seal with instruments passed therethrough such that the anti-microbial agent sterilizes the instruments.

26. The method of claim 21, wherein the anti-microbial agent comprises a solution and the method further comprises delivering the solution to the flexible tube.
