The invention generally relates to a rotational imaging apparatus and methods of use thereof. In certain aspects, the apparatus includes a hollow elongate body. The hollow body includes a proximal and a distal end, and the proximal end includes a connector. A rotatable drive member is disposed within the body, and a rotatable electrical signal transmission member is disposed within the drive cable. The drive member and the electrical signal transmission member are coupled to an imaging device within the body and a portion of the electrical signal transmission member is attached to the drive member distal to the connector.
