Transvascular medical lead

摘要

A medical electrical lead and methods of implanting medical electrical leads in lumens. Leads in accordance with the invention employ preformed biases to stabilize the lead within a lumen or lumen and to provide feedback to lead implanters. In some embodiments, a preformed bend in the lead may assist an implanter with orienting the lead within a lumen.
