Systems for visualizing interior tissue regions including an actuator to move imaging element

摘要: An imaging element characterizes tissue morphology by analyzing perfusion patterns of a contrast media in visualized the element, to identify infarcted tissue. In preferred implementation, catheter tube introduced into heart region carries as well support structure spaced from which contacts endocardial The is moved visualizes A selected electrical event sensed surrounding myocardial tissue, regulates movement element. stabilizes moving it providing resistance dislodgment or disorientation despite presence dynamic forces.
