摘要：Methods and apparatuses for positioning medical devices onto (or close to) adesired portion of the interior wall of an internal channel, such as for scan imaging, forphotodynamic therapy and/or for optical temperature measurement. In oneembodiment, a catheter assembly has a distal portion that can be changed from aconfiguration suitable for traversing the internal channel to another configurationsuitable for scan at least a spiral section of the interior wall of an internal channel, such asan artery. In one example, the distal portion spirals into gentle contact with (or close to)a spiral section of the artery wall for Optical Coherence Tomography (OCT) scanning. Thespiral radius may be changed through the use of a guidewire, a tendon, a spiral balloon, atube, or other ways.
