LEAD CONFIGURED FOR HISIAN, PARA-HISIAN, RV SEPTUM AND RV OUTFLOW TRACT PACING

摘要

Disclosed herein is an implantable medical lead for implantation within a right ventricle of a heart and powered by an implantable pulse generator. The lead includes a lead body having a proximal end configured to couple to the generator, a distal end, an electrode at the distal end, and a distal portion extending proximally from the distal end. When the distal portion is in a non-deflected state, the distal portion biases to assume a configuration including first, second and third generally straight segments and first and second bends. The first segment is proximal of the distal end, the second segment is proximal of the first segment, the third segment is proximal of the second segment, the first bend is between the first and second segments, and the second bend is between the second and third segments. When the distal portion is implanted in the right ventricle, the configuration is at least partially the cause of the electrode being at least one of: positioned against the right ventricle septum; positioned in the outflow tract of the right ventricle; positioned for Hisian pacing; and positioned for para-Hisian pacing.
