Epicardial defibrilation lead with side helix fixation and placement thereof

A medical device system comprising:

• a delivery device having a proximal end and a distal end with an interior therebetween, the distal end having a distal tip and an opening to an interior of the delivery device, the opening extending longitudinally proximal from the distal end of the device, the opening defined by longitudinally extending side edges and a distal edge at the distal end of the delivery device;
• an implantable medical electrical epicardial lead that comprises:
• (a) an insulative lead body that includes a proximal end and a distal end;
• (b) at least one conductor disposed in the lead body;
• and
• (c) a side helical fixation member, disposed a distance from the distal end, the side helical fixation member comprising a set of windings configured to wrap around the lead body circumference, the side helical fixation member including a distal tip comprising a sharpened elongated free end and comprising a final one of the windings defining an angle of 15 degrees or less with regard to a line perpendicular to the centerline.
