- a first tube having a lumen extending therethrough;
an elongate flexible housing having a lumen extending therethrough, the housing being received within the first tube but not extending proximally beyond the proximal end of the first tube;
a second tube having a lumen therethrough and positioned within the lumen of the first tube at the proximal end and extending beyond the proximal end of the first tube, but not beyond the distal end of the first tube;
at least one illuminating fiber extending through and proximally beyond the lumen of the housing and the lumen of the first tube and into the lumen of the second tube; and
wherein the housing is not fixably attached to the first tube and is free to rotate within the first tube and the distal end of the second tube and the proximal end of the first tube are fixably attached.

Abstract
An illuminating wire medical device may include an elongate flexible housing and an illuminating fiber and a core wire extending through at least part of the housing, the core wire providing desired pushability and torquability. The illuminating device may further include a connector assembly cooperating with the illuminating fiber to accommodate changes in length, to absorb forces applied during use of the device and to channel errant light away from the illuminating fibers of the device.
