Abstract
A system is transluminally advanced into a subject. A first portion of the system is positioned adjacent a cardiovascular tissue of the subject, the system including wires disposed at the first portion. The first portion is stabilized at the cardiovascular tissue by positioning a distal portion of the system against a cardiovascular wall of the subject. While the distal portion of the system remains against the cardiovascular wall, the wires are induced to bow laterally such that the wires press against the cardiovascular tissue. While the wires remain pressed against the cardiovascular tissue, the shape of the wires is radiographically imaged. While (i) the first portion remains stabilized, and (ii) the wires remain pressed against the cardiovascular tissue, at least a portion of the system is transluminally implanted at the cardiovascular tissue, facilitated by the imaging. Other embodiments are also described.
