Abstract

A catheter assembly includes a catheter body extending from a catheter proximal portion to a catheter distal portion. The catheter body includes an inner liner and an outer sleeve. A braid assembly is within the catheter body and between the inner liner and the outer sleeve. The braid assembly includes a first filar array including one or more first filars helically extending around the catheter body in a first direction. The braid assembly further includes a second filar array including one or more second filars helically extending around the catheter body in a second direction opposed to the first direction.

Claims (39)

1. A catheter assembly comprising:

a catheter body extending from a catheter proximal portion to a catheter distal portion, the catheter body includes:

an inner liner having a catheter body inner diameter, the inner liner extending around a catheter lumen;

an outer sleeve having a catheter body outer diameter; and

a braid assembly within the catheter body and between the inner liner and the outer sleeve, the braid assembly includes:

a first filar array including one or more first filars helically extending along the catheter body in a first direction, wherein the one or more first filars include a first rectangular profile of 0.003 inches in width by 0.0007 inches in thickness; and

a second filar array including:

a first set of second filars helically extending along the catheter body in a second direction, wherein the first set of second filars include the first rectangular profile; and

a second set of second filars helically extending along the catheter body in the second direction, wherein the second set of second filars include a second rectangular profile of 0.008 inches in width by 0.002 inches in thickness;

wherein the outer sleeve penetrates the braid assembly and contacts the inner liner; and

wherein the catheter body includes a wall thickness between the catheter body inner and outer diameters of around 0.0040 inches.

2. The catheter assembly of claim 1 , wherein the inner liner includes an inner liner thickness of 0.00075 inches, and the outer sleeve includes an outer sleeve thickness of 0.0005 inches.

3. The catheter assembly of claim 1 , wherein the braid assembly is layered over the inner liner, and the outer sleeve is layered over the braid assembly.

4. The catheter assembly of claim 1 , wherein the one or more first filars of the first filer array includes eight first filars;

the first set of second filars of the second filar array include four second filars; and

the second set of second filars of the second filar array include four second filars.

5. The catheter assembly of claim 1 , wherein the first filar array includes a first kink-resistance; and

the second filar array includes a second kink resistance greater than the first kink resistance.

6. The catheter assembly of claim 1 , wherein the second set of second filars of the second filar array include a braided brace with a second kink resistance greater than a first kink resistance of the first set of second filars of the second filar array.

7. The catheter assembly of claim 6 , wherein the braided brace with the second kink resistance is greater than a third kink resistance of the first filar array.

8. The catheter assembly of claim 6 , wherein the braided brace includes four of the second filars with the second rectangular profile.

9. A catheter assembly comprising:

a catheter body extending from a catheter proximal portion to a catheter distal portion, the catheter body includes:

an inner liner having a catheter body inner diameter, the inner liner extending around a catheter lumen;

an outer sleeve having a catheter body outer diameter; and

a braid assembly within the catheter body and between the inner liner and the outer sleeve, the braid assembly includes:

a first filar array including at least eight first filars helically extending along the catheter body in a first direction, wherein the first filars include a first rectangular profile of 0.003 inches in width by 0.0007 inches in thickness; and

a second filar array including:

a set of four filars helically extending along the catheter body in the second direction, wherein the set of four filars include the first rectangular profile; and

a braided brace helically extending along the catheter body in the second direction, wherein the braided brace includes filars having a second rectangular profile of 0.008 inches in width by 0.002 inches in thickness;

wherein the outer sleeve penetrates the braid assembly and contacts the inner liner; and

wherein the catheter body includes a wall thickness between the catheter body inner and outer diameters of around 0.0040 inches.

10. The catheter assembly of claim 9 , wherein the inner liner includes an inner liner thickness of 0.00075 inches, and the outer sleeve includes an outer sleeve thickness of 0.0005 inches.

11. The catheter assembly of claim 9 , wherein the braid assembly is layered over the inner liner, and the outer sleeve is layered over the braid assembly.

12. The catheter assembly of claim 9 , wherein the first filar array includes a first kink-resistance; and

the second filar array includes a second kink resistance greater than the first kink resistance.

13. The catheter assembly of claim 9 , wherein the braided brace includes a second kink resistance greater than a first kink resistance of the set of four filars of the second filar array.

14. The catheter assembly of claim 13 , wherein the second kink resistance of the braided brace is greater than a third kink resistance of the first filar array.

15. The catheter assembly of claim 9 , wherein the filars of the braided brace includes four filars having the second rectangular profile.
