Abstract
Apparatus and methods for determining positioning of a energy delivery element include deploying a energy delivery element at a treatment site proximal to a vessel wall; using a multi-region pressure sensing apparatus to sense pressures applied in a plurality of directions about the energy delivery element; and determining an orientation of the energy delivery element based on the pressures measured in the plurality of directions about the energy delivery element.
