Abstract

A fastening device is for anchoring a surgical or diagnostic medical aid in the tissue of a human or animal hollow organ. The fastening device includes an anchor head, which is configured to penetrate the tissue; a driving device for driving the anchor head into the tissue; and a trigger device to trigger the driving of the anchor head into the tissue.

Claims

1. Fastening device for anchoring at least one of a surgical and diagnostic medical aid in tissue of at least one of a human and animal hollow organ, the device comprising:

an anchor head, configured to penetrate the tissue;

a driving device for driving the anchor head into the tissue; and

a trigger device for releasing the driving of the anchor head into the tissue.

2. Fastening device according to claim 1, wherein the trigger device is integrated in the driving device.

3. Fastening device according to claim 1, wherein the driving device includes a spring element as a driver.

4. Fastening device according to claim 1, wherein the driving device includes a gas pressure element as a driver.

5. Fastening device according to claim 1, wherein the driving device includes a runner to hold the anchor head.

6. Fastening device according to claim 1, wherein the anchor head includes a shank-like segment.

7. Fastening device according to claim 1, wherein at least one anchoring element is configured on the anchor head.

8. Fastening device according to claim 7, wherein the at least one anchoring element has the form of a barb.

9. Fastening device according to claim 7, wherein the at least one anchoring element is configured as an expansion device with at least one arbor.

10. Fastening device according to claim 9, wherein the at least one arbor of the expansion device is openable by an opening device.

11. Fastening device according to claim 9, wherein the at least one arbor of the expansion device is configured as a self-expanding arbor when subject to a tensile force.

12. Fastening device according to claim 2, wherein the driving device includes a spring element as a driver.

13. Fastening device according to claim 2, wherein the driving device includes a gas pressure element as a driver.

14. Fastening device according to claim 2, wherein the driving device includes a runner to hold the anchor head.

15. Fastening device according to claim 2, wherein the anchor head includes a shank-like segment.

16. Fastening device according to claim 5, wherein the anchor head includes a shank-like segment.

17. Fastening device according to claim 2, wherein at least one anchoring element is configured on the anchor head.

18. Fastening device according to claim 17, wherein the at least one anchoring element has the form of a barb.

19. Fastening device according to claim 8, wherein the at least one anchoring element is configured as an expansion device with at least one arbor.

20. Fastening device according to claim 10, wherein the at least one arbor of the expansion device is configured as a self-expanding arbor when subject to a tensile force.

28. A medical aid including the fastening device of claim 1.

29. A probe including the fastening device of claim 1.

21. A device for anchoring a probe in tissue of at least one of a human and animal organ, the device comprising:

means for penetrating the tissue;

means for driving the anchor head into the tissue; and

means for releasing the driving of the anchor head into the tissue.

22. The device according to claim 21, wherein the means for driving and the means for releasing are integrated.

23. The device according to claim 21, wherein the means for penetrating includes an anchor head.

24. The device according to claim 23, wherein the anchor head includes a shank-like segment.

25. The device according to claim 23, wherein at least one anchoring element is configured on the anchor head.

26. The device according to claim 21, wherein the medical aid is at least one of a surgical and diagnostic medical aid.

27. The device according to claim 21, wherein the fastening device is for anchoring a probe in tissue of at least one of a human and animal hollow organ.

30. A probe including the device of claim 21.
