Abstract:
1. A medical device for altering tissue structure within a passageway in a body, comprising: an elongate member defining a first axis, the elongate member having proximal and distal ends; an active member located proximate the distal end of the elongate member, the active member including an elongated energy transfer element, a lateral portion of the elongated energy transfer element being adapted to contact or come in close proximity to a tissue wall of the passageway when a length of the elongated energy transfer element is at least substantially aligned with a length of the passageway; and a junction having a first side coupled to the distal end of the elongate member and a second side coupled to a proximal end of the active member, the second side being opposite the first side, and the junction providing angular adjustment of the active member relative to the elongate member about the junction, wherein the junction is configured to angularly adjust the active member relative to the elongate member about the junction during movement of the active member through a passageway having a longitudinal axis that is not aligned with the first axis, and wherein the junction is configured to angularly adjust the active member without user manipulation of the device.
