A method of advancing a guidewire having an imaging device disposed thereon within a cavity of a body includes placing a guidewire into a cavity of a body, said guidewire having an image sensor disposed about a guide member on a distal end of the guidewire and a plurality of power lines operatively coupled to the guide member and the image sensor. At least two power lines of the plurality of power lines are disposed on opposing sides of the guide member and extend from the distal end of the guidewire to a proximal end of the guidewire. As the guidewire is advanced through the body cavity, the distal end of the guidewire is positioned by pulling one of the at least two power lines while maintaining the position of the other of the at least two power lines.
