1. An intravascular device for delivering a device to a target location within a patient'"'"'s anatomy, the intravascular device comprising:
- a monolithic elongated body having a proximal end and a distal end, at least part of the elongated body being made of a body material and having a length therebetween;
a major lumen defined by the elongated body and extending from the proximal end to the distal end;
a plurality of minor lumen defined by the elongated body and extending from the proximal end through at least a portion of the length of the elongated body, the minor lumen being fixed relative to the major lumen in transverse cross-section, a wall ratio of a thickness of a lumen wall between the major lumen and one of the plurality of minor lumens relative to a radius of the elongated body being within a range of 0.100 and 0.150; and
a reinforcement layer connected to the elongated body and forming an outer surface of the intravascular device when the intravascular device is used to deliver the device to the target location within the patient'"'"'s anatomy, the reinforcement layer including a reinforcement material having a greater elastic modulus than the body material.

Abstract
An intravascular device includes a shaft having a body defining a major lumen and a plurality of minor lumen. The minor lumens are spaced about the major lumen. The major lumen and the plurality of minor lumen extend from a proximal end of the body to a distal end of the body. One or more wires may extend through the major lumen and/or minor lumen.
