Abstract

Venous endoluminal devices, in particular for the treatment of defects of the veins, are provided with a substantially tubular body which defines an inner lumen and support modules oriented longitudinally and joined, in a distal direction, by distal bridges and in a proximal direction, by proximal bridges. Each support module includes a distal section, extending in a distal direction beyond the distal bridges, wherein the distal section is at least partially projecting in a radial direction, internally in relation to the inner lumen of the body. Methods of treatment using such devices are also provided.

Claims

1-17. -17. (canceled)

18. An endoluminal venous device comprising a substantially tubular body which defines an inner lumen and support modules joined by transversal bridges, wherein the support modules have a proximal radial width (Wp) less than a distal radial width (Wd) and have a convex shape,

and wherein the support modules extend along the entire length of the tubular body and are internally empty, without bridges or other internal elements, so as to permit a partial collapse of venous walls towards the inner lumen of the tubular body and to maintain the physiological compliance of the vein.

19. The device of claim 18, wherein the tubular body has a truncated-cone shape.

20. The device of claim 18, wherein the tubular body defines an inner lumen and the support modules are oriented longitudinally and joined, in a distal direction, by distal bridges and in a proximal direction, by proximal bridges, wherein each support module comprises a distal section, extending in a distal direction beyond the distal bridges and wherein the distal section is at least partially projecting in a radial direction, internally in relation to the inner lumen of the body.

21. The device of claim 18, wherein the tubular body defines an inner lumen and the support modules are oriented longitudinally and joined, in a distal direction, by distal bridges and in a proximal direction, by proximal bridges, wherein each support module comprises a proximal section, extending in a proximal direction beyond the proximal bridges, and wherein the proximal section is at least partially projecting in a radial direction, externally in relation to the inner lumen of the body.

22. The device of claim 20, wherein the tubular body comprises:

a truncated conical central portion, with a greater diameter in a distal direction and

a truncated conical distal end, having the same conicity as the central portion,

and wherein the distal bridges are positioned in the area where the distal portion and the central portion join.

23. The device of claim 22, wherein the tubular body further comprises a truncated conical proximal end having an opposite conicity to the central portion, and wherein the proximal bridges are positioned in the area where the proximal portion and the central portion join.

24. The device of claim 20, wherein each support module comprises a proximal section, extending in a proximal direction beyond the proximal bridges, wherein the proximal section is at least partially projecting in a radial direction, externally in relation to the inner lumen of the body.

25. The device of claim 21, wherein each support module comprises a distal section, extending in a distal direction beyond the distal bridges, wherein the distal section is at least partially projecting in a radial direction, internally in relation to the inner lumen of the body.

26. The device of claim 20, wherein the tubular body has a truncated conical shape at both ends and has a substantially hour-glass shape.

27. The device of claim 20, wherein the transversal bridges have a substantially V-shape or gull wing shape.

28. The device of claim 18, wherein the bridges comprise distal bridges and proximal bridges and wherein the distal bridges are longer than the proximal bridges.

29. The device of claim 18, wherein the support modules are joined by transversal bridges so as to form a plurality of connection cells, wherein the support modules are larger than the connection cells.

30. The device of claim 18, wherein the support modules extend beyond the connection cells in a distal direction and/or in a proximal direction.

31. The device of claim 29, wherein the connection cells have a proximal radial width (Wp) less than the distal radial width (Wd).

32. The device of claim 18, comprising four support modules angularly equidistant from each other in a radial direction.

33. The device of claim 18, wherein the tubular body comprises self-expanding material.

34. The device of claim 33, wherein the self-expanding material comprises nitinol.
