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.
Claims45
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;
- and
- an outer sleeve;
- 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 around the catheter body in a first direction;
- and
- a braided brace interlaced with the first filar array, the braided brace extends around the catheter body in a second direction opposed to the first direction, wherein the braided brace anchors and supports the first filar array, and the braided brace includes a coil.
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, and an outer sleeve;
- 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 around the catheter body in a first direction;
- 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;
- and
- wherein at least one of the first or second filar arrays includes at least one guide recess helically extending with the first or second filars;
- and
- a coil is received in the at least one guide recess and extends helically around the catheter body with the first or second filars.
A catheter assembly comprising:
- a catheter body extending from a catheter proximal portion to a catheter distal portion, the catheter body includes:

- and
- an outer sleeve;
- 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 around the catheter body in a first direction;
- 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;
- and
- wherein the braid assembly includes at least one guide recess extending along one of the first or second filar arrays, and a coil is received within the at least one guide recess.
