Abstract

An apparatus for stabilizing an anatomical structure includes a combination of repeating rigid elements within a single flexible element. While applicable to routine open surgical techniques and to a variety of anatomical structures, the system is especially applicable to minimally invasive endoscopic/robotic mitral valve repair. An annuloplasty system according to the invention is immediately intuitive, logical and simple to use.

Claims

1. Apparatus for stabilizing an anatomical structure, the apparatus comprising:

a plurality of discrete suture support platforms, the plurality of discrete suture support platforms being constructed and arranged for disposition at the anatomical structure to stabilize the anatomical structure; and

covering material constructed and arranged to cover the plurality of discrete suture support platforms, the covering material being formed into a plurality of pockets, at least one discrete suture support platform being contained within each pocket;

wherein each suture support platform is constructed and arranged to receive and support suture extending from the platform through the covering material to secure the platform with respect to the anatomical structure at a precise location.

2. The apparatus of claim 1, wherein the covering material comprises a segmented tube, each segment of the tube corresponding to one of said pockets.

3. The apparatus of claim 1, wherein the covering material is constructed and arranged to maintain the discrete suture support platforms in a desired overall shape but to allow relative movement between adjacent suture support platforms to accommodate the particular shape of the anatomical structure.

4. The apparatus of claim 1, wherein the plurality of discrete suture support platforms and covering material are arranged in a line such that the apparatus has opposite ends that are free of direct connection to each other.

5. The apparatus of claim 4, wherein the discrete suture support platforms each define at least one aperture therethrough, the at least one aperture of each suture support platform being constructed to receive and support suture for attaching each platform with respect to the anatomical structure at a precise location;

further wherein the apertures of the platforms are constructed and arranged to create a plication region in the anatomical structure beneath each platform so as to reduce the length of the anatomical structure by a precise amount along the line.

6. The apparatus of claim 4, wherein the covering material is constructed to be cut between platforms such that the line is of a desired length before being secured with respect to the anatomical structure.

7. The apparatus of claim 1, wherein the discrete suture support platforms each define at least one aperture therethrough, the at least one aperture of each suture support platform being constructed to receive and support suture for attaching each platform with respect to the anatomical structure at a precise location, such that the anatomical structure is stabilized.

8. The apparatus of claim 1, wherein said suture is first suture;

further wherein the covering material is attached to each discrete suture support platform by second suture.

9. The apparatus of claim 8, wherein said second suture passes through at least one aperture of the suture platform.

10. The apparatus of claim 9, wherein said second suture is tied in a knot, the knot being disposed directly adjacent the at least one aperture to indicate location of the at least one aperture.

11. The apparatus of claim 8, wherein said second suture is disposed and arranged to guide the placement of said first suture through the covering material.

12. The apparatus of claim 8, further comprising third suture constructed and arranged between the suture support platforms to form the pockets;

wherein the third suture is of a contrasting color relative to said covering material.

13. The apparatus of claim 1, the apparatus being in combination with said suture.

14. The apparatus of claim 1, wherein said pockets are all generally identical;

further wherein said platforms are all generally identical.

15. The apparatus of claim 1, wherein each pocket is a completely closed pocket.

16. The apparatus of claim 1, wherein each suture support platform comprises two apertures therethrough;

further wherein the covering material supports a visual indication of the location of the apertures.

17. The apparatus of claim 1, wherein the visual indication comprises suture.

19. The apparatus of claim 18, wherein an outer surface of the tube defines at least one narrowed portion between each suture platform.

20. The apparatus of claim 18, wherein the tube is constructed to be readily cut to define a desired length of the tube, such that one of the free opposite ends is separated from the remainder of the tube.

21. The apparatus of claim 18, constructed and arranged to be introduced through a small-diameter endoscope.

22. The apparatus of claim 21, wherein the apparatus can be introduced through a small-diameter endoscope without being narrowed, disassembled or otherwise altered.

23. The apparatus of claim 18, further comprising bonding agent to secure each suture platform with respect to the tube.

24. The apparatus of claim 18, wherein the tube defines at least one external guide feature arranged to accurately guide and direct suture placement with respect to each suture platform.

25. The apparatus of claim 24, wherein the at least one external guide feature comprises suture.

26. The apparatus of claim 25, wherein said suture holds each platform in place inside the tube.

27. The apparatus of claim 24, wherein the at least one external guide feature comprises a color contrast.

28. The apparatus of claim 24, wherein the at least one external guide feature indicates location of an aperture within each platform.

29. The apparatus of claim 18, wherein one of the suture platforms is a middle suture platform of the apparatus;

further wherein the tube at the middle suture platform is of a contrasting color to the remainder of the tube.

30. The apparatus of claim 18, further comprising sizing features disposed along the tube, wherein the sizing features are constructed and arranged to indicate the length of the anatomical structure based on the number of sizing features needed to extend along an entire desired portion of the anatomical structure.

31. The apparatus of claim 30, wherein the sizing features comprise suture.

32. The apparatus of claim 18, wherein the tube comprises polyester.

33. The apparatus of claim 18, wherein each discrete suture platform is constructed and arranged to receive and support suture passing through the tube and into the anatomical structure such that the tube is secured with respect to and stabilizes the anatomical structure.

34. The apparatus of claim 33, wherein the tube defines a waist between each suture platform;

the apparatus being constructed and arranged to receive and support suture passing through at least one waist of the tube and into the anatomical structure such that the tube is additionally secured with respect to and additionally stabilizes the anatomical structure.

35. The apparatus of claim 34, wherein said suture passing through the at least one waist of the tube is arranged to plicate the anatomical structure without plicating the tube.

36. The apparatus of claim 18, constructed and arranged for use in an annuloplasty procedure.

38. The combination of claim 37, wherein the endoscope is constructed and arranged for use during a robotic endoscopic procedure.

18. Apparatus for stabilizing an anatomical structure, the apparatus being introduced to the anatomical structure during a surgical procedure, the apparatus comprising:

a tube having free opposite ends; and

a plurality of discrete suture platforms disposed within and secured with respect to the tube before the surgical procedure begins, each discrete suture platform being constructed and arranged to support suture.

37. In combination:

apparatus for stabilizing an anatomical structure, the apparatus being introduced to the anatomical structure during a surgical procedure, the apparatus comprising;

a tube having free opposite ends; and

a plurality of discrete suture platforms disposed within and secured with respect to the tube before the surgical procedure begins, each discrete suture platform being constructed and arranged to support suture; and

an endoscope for receiving and introducing said apparatus during the surgical procedure.
