Abstract

Claims (31)

1 . An intravascular device comprising:

a balloon; and

a plurality of strips, each strip of the plurality of strips comprising an inferior facing surface adhered to the balloon, a first sloped side wall, and a second sloped side wall, each strip of the plurality of strips including a plurality of wedge dissectors spaced apart along a surface of each strip, each strip extending along an outer surface of the balloon,

wherein the wedge dissectors comprise a base surface, and an unhoned radially outward facing surface;

wherein the balloon is configured to partially expand and create a plurality of lobes between the plurality of strips, wherein a first lobe of the plurality of lobes comprises a first bulbous shape that contacts the first sloped side wall of a first strip of the plurality of strips and contacts the second sloped side wall of a second strip of the plurality of strips, wherein a second lobe of the plurality of lobes comprises a second bulbous shape that contacts the first sloped side wall of the second strip of the plurality of strips and the second sloped side wall of a third strip of the plurality of strips, and

wherein the first lobe and the second lobe apply a force to the sloped side walls of the first strip to rotate the first strip from a generally tangential orientation to a generally perpendicular orientation.

2 . The intravascular device of claim 1 , wherein the first lobe and the second lobe apply a force to the sloped side walls of the first strip to rotate the first strip from the generally perpendicular orientation to the generally tangential orientation.

3 . The intravascular device of claim 1 , wherein the intravascular device is bi-directional to allow the plurality of strips to rotate clockwise or counterclockwise.

4 . The intravascular device of claim 1 , wherein the plurality of strips point counterclockwise in the generally tangential orientation before inflation.

5 . The intravascular device of claim 1 , wherein the plurality of strips point counterclockwise in the generally tangential orientation after inflation.

6 . The intravascular device of claim 1 , wherein the plurality of strips are at least partially covered by a pleat of the balloon in the generally tangential orientation.

7 . The intravascular device of claim 1 , wherein each strip of the plurality of strips is at least partially covered by a pleat of the balloon when the balloon is deflated.

8 . The intravascular device of claim 1 , wherein the sloped side walls in combination with the expansion of the first lobe and the second lobe are configured to allow for more effective control of the generally perpendicular orientation of the wedge dissectors.

9 . The intravascular device of claim 1 , wherein the unhoned radially outward facing surface is configured to contact a vessel wall while creating little to no separation of plaque from the vessel wall.

10 . The intravascular device of claim 1 , wherein the plurality of lobes are configured to exert a force on the vessel wall causing the vessel wall to pull away from the wedge dissectors.

11 . The intravascular device of claim 1 , wherein the plurality of lobes are configured to exert a force on the vessel wall that allows the unhoned radially outward facing surface to create serrations in the vessel wall.

12 . The intravascular device of claim 1 , wherein the plurality of lobes are configured to exert a force on the vessel wall that allows the unhoned radially outward facing surface to create linear dissected lines.

13 . The intravascular device of claim 1 , wherein the sloped side walls of the plurality of strips in combination with the expansion of the plurality of lobes are configured to produce a plurality of longitudinally oriented lines to a medial layer that provide lumen gain independent of an arterial dimension.

14 . The intravascular device of claim 1 , wherein the sloped side walls in combination with the expansion of the lobes are configured to change the pressure distribution at a vessel wall allowing the wedge dissectors to further penetrate the vessel wall.

15 . The intravascular device of claim 1 , wherein the balloon is configured to deliver energy.

16 . The intravascular device of claim 1 , wherein the strips increase trackability and pushability by translating forces longitudinally along the balloon.

17 . An intravascular device comprising:

a balloon; and

a plurality of strips, each strip of the plurality of strips including a plurality of wedge dissectors spaced apart along a surface of each strip, each strip extending along an outer surface of the balloon,

wherein the wedge dissectors comprise a base surface, an unhoned radially outward facing surface, and sloped side walls extending from the base surface to the unhoned radially outward facing surface;

wherein the balloon is configured to expand and create lobes between the plurality of strips, wherein the lobes contact nearly the entire circumference of a vessel wall when the plurality of strips are oriented perpendicularly, wherein the lobes are filled before the wedge dissectors penetrate the vessel wall, and

wherein the sloped side walls in combination with the expansion of the lobes are configured to produce a plurality of longitudinally oriented lines to a medial layer that increase volumetric blood flow.

18 . The intravascular device of claim 17 , wherein the sloped side walls in combination with the expansion of the lobes are configured to produce a plurality of longitudinally oriented lines to the medial layer that improves stenosis.

19 . The intravascular device of claim 17 , wherein the sloped side walls in combination with the expansion of the lobes are configured to cause positive vessel remodeling.

20 . The intravascular device of claim 17 , wherein the sloped side walls in combination with the expansion of the lobes are configured to maintain the generally perpendicular orientation of the wedge dissectors as the wedge dissector induce nodes of separation in an intima.

21 . The intravascular device of claim 17 , wherein the balloon is configured to deliver energy.
