1. A medical device comprising:
an elongate tubular body with an outer diameter of no more than 0.0835 inches (2.1209 mm), an inner diameter of no less than 0.0715 inches (1.8161 mm), a proximal end, a distal end, and a total length therebetween; and a sole reinforcement tubular structure embedded in polymer between the outer diameter and the inner diameter of the elongate tubular body from the proximal end of the elongate tubular body to proximal to the distal end of the elongate tubular body, the sole reinforcement tubular structure made solely of a first plurality of elongate wire ribbons and a second plurality of elongate wire members braided together in a braid configuration; wherein
each of the first plurality of elongate wire members arranged in a counter-clockwise helix about a central longitudinal axis of the elongate tubular body and having a first constant transverse cross-sectional shape, which first cross-sectional shape has a maximum thickness and a maximum width, the maximum width being at least three times as great as the maximum thickness and no more than four and a half times as great as the maximum thickness; andeach of the second plurality of elongate wire members arranged in a clockwise helix about the central longitudinal axis of the elongate tubular body and having a second constant transverse cross-sectional shape, which second cross-sectional shape has a maximum thickness and a maximum width, the maximum width being at least two times a great as the maximum thickness and no more than three times as great as the maximum thickness. |
