1. A myocardial lead attachment system for securing a distal end of a lead within a myocardium of a patient'"'"'s heart, the system comprising:
- a lead body;
an anchor mechanism for engaging the heart, said anchor mechanism coupled to the lead body and formed of a bioabsorbable or biodegradable polymer; and
a surface feature formed on a portion of the lead body for promoting formation of scar tissue around said portion of the lead body.
