Abstract

Claims (35)

1 . An intravascular device formed from a stock material, the intravascular device comprising:

an elongated member extending between a proximal end and a distal end along a longitudinal axis, and having a plurality of fenestrations that define a plurality of axially extending beams and circumferentially extending rings in a one-beam cut pattern, wherein between each pair of adjacent circumferentially extending rings is disposed a single axially extending beam without other axially extending beams;

wherein at least one beam of the one-beam cut pattern includes an interior surface, an exterior surface, and a pair of lateral surfaces, wherein the lateral surfaces are substantially planar;

wherein an angle formed between the interior surface and one or both of the lateral surfaces is between about 75 degrees and about 120 degrees;

wherein an angle formed between the exterior surface and one or both lateral surfaces is greater than about 45 degrees; and

wherein the at least one beam of the one-beam cut pattern has a shape resulting from cutting the stock material to a depth of 30% to 70% of the stock material diameter from a first angle, and cutting the stock material to a depth of 30% to 70% of the stock material diameter from a second angle, wherein the first angle and the second angle are 60 degrees to 120 degrees apart.

2 . The device of claim 1 , wherein the angle formed between the interior surface and one or both of the lateral surfaces is between about 80 degrees and about 120 degrees.

3 . The device of claim 1 , wherein the elongated member is a tube structure.

4 . The device of claim 3 , further comprising a core disposed within the tube structure.

5 . The device of claim 3 , further comprising an inner tube disposed within the tube structure.

6 . The device of claim 3 , further comprising one or more coils disposed within the tube structure.

7 . The device of claim 1 , wherein the elongated member comprises a polymer.

8 . The device of claim 1 , wherein the rings and beams are encapsulated in a polymer.

9 . The device of claim 1 , wherein the elongated member comprises a nickel-titanium alloy.

10 . The device of claim 1 , wherein the elongated member comprises stainless steel.

11 . The device of claim 1 , wherein the elongated member is formed from two or more different materials.

12 . The device of claim 1 , wherein the at least one beam has a substantially uniform thickness across its circumferential length.

13 . The device of claim 1 , wherein the angle formed between the exterior surface and one or both lateral surfaces is about 50 degrees to about 90 degrees.

14 . The device of claim 1 , wherein the intravascular device is a guidewire.

15 . The device of claim 1 , wherein the intravascular device is a microcatheter.

16 . An intravascular device formed from a stock material, the intravascular device comprising:

an elongated member extending between a proximal end and a distal end along a longitudinal axis, and having a plurality of fenestrations that define a plurality of axially extending beams and circumferentially extending rings in a one-beam cut pattern, wherein between each pair of adjacent circumferentially extending rings is disposed a single axially extending beam without other axially extending beams;

wherein at least one beam of the one-beam cut pattern includes an interior surface, an exterior surface, and a pair of lateral surfaces;

wherein an angle formed between the interior surface and one or both of the lateral surfaces is between about 75 degrees and about 130 degrees, and

wherein an angle formed between the exterior surface and one or both lateral surfaces is greater than about 45 degrees, and

wherein the at least one beam of the one-beam cut pattern has a shape resulting from cutting the stock material to a depth of 30% to 70% of the stock material diameter from a first angle, and cutting the stock material to a depth of 30% to 70% of the stock material diameter from a second angle, wherein the first angle and the second angle are 60 degrees to 120 degrees apart.

17 . An intravascular device formed from a stock material, the intravascular device comprising:

an elongated member extending between a proximal end and a distal end along a longitudinal axis, and having a plurality of fenestrations that define a plurality of axially extending beams and circumferentially extending rings in a one-beam cut pattern, wherein between each pair of adjacent circumferentially extending rings is disposed a single axially extending beam without other axially extending beams;

a core disposed within the tube structure; and

one or more coils disposed within the tube structure;

wherein at least one beam of the one-beam cut pattern includes an interior surface, an exterior surface, and a pair of lateral surfaces, wherein the lateral surfaces are substantially planar;

wherein an angle formed between the interior surface and one or both of the lateral surfaces is about 80 degrees to about 120 degrees;

wherein an angle formed between the exterior surface and one or both lateral surfaces is about 50 degrees to about 90 degrees; and

wherein the at least one beam of the one-beam cut pattern has a shape resulting from cutting the stock material to a depth of 30% to 70% of the stock material diameter from a first angle, and cutting the stock material to a depth of 30% to 70% of the stock material diameter from a second angle, wherein the first angle and the second angle are 60 degrees to 120 degrees apart.

18 . The device of claim 1 , wherein the lateral surfaces of the at least one beam are substantially perpendicular to interior surface.
