A system and method of implanting pacing lead in a patient's heart. The system may include a catheter configured to by inserted through the coronary sinus ostium such that the distal end region of the catheter is positioned past the anterolateral vein and proximate at least one septal perforating vein. The catheter is configured to inject contrast proximate the septal perforating vein to identify an implant region for a pacing lead. Further, a controller is configured to deliver pacing therapy to the implant region.

Septal perforating vein pacing

A medical device lead includes an insulated lead body including at least one electrode, a helically coiled conductor electrically coupled to the at least one electrode, and one or more polymer coils formed coaxially with the helically coiled conductor. The helically coiled conductor includes a plurality of turns having a conductive coil pitch and including one or more conductive filars each having a conductive filar diameter. The one or more polymer coils provide at least about 25 &#x3bc;N&#xb7;m of torque transmitting capacity along a length of the medical device lead.
