1. A wireguide, comprising:
a connector having a connector first end, a connector second end, and a circumferential wall defining a connector outer surface and a connector lumen extending between the connector first end and the connector second end, the connector defining a connector outer diameter;
a first segment having a first segment first end, a first segment second end, a first segment body extending between the first segment first end and the first segment second end, a first segment end portion extending from the first segment second end to a location on the first segment body between the first segment first end and the first segment second end, and a first segment coating disposed on the first segment end portion, the first segment body having a first segment body outer surface and defining a first segment body outer diameter equal to the connector outer diameter, the first segment end portion defining a first segment end portion outer diameter that is less than the first segment body outer diameter and disposed in the connector lumen such that the connector outer surface is flush with the first segment body outer surface;
a second segment having a second segment first end, a second segment second end, a second segment body extending between the second segment first end and the second segment second end, a second segment end portion extending from the second segment first end to a location on the second segment body between the second segment first end and the second segment second end, and a second segment coating disposed on the second segment end portion, the second segment body having a second segment body outer surface and defining a second segment body outer diameter equal to the connector outer diameter, the second segment end portion defining a second segment end portion outer diameter that is less than the second segment body outer diameter and disposed in the connector lumen such that the connector outer surface is flush with the second segment body outer surface; and
a wireguide coating disposed over the first segment, the second segment, and the connector.
