A lead having a distal end electrode assembly adapted for implantation on
or about the heart or within a vein and for connection to a system for
monitoring or stimulating cardiac activity. The electrode assembly
includes conductive fixation features, such as conductive tines or
flexible members, in combination with non-conductive fixation features.
The conductive fixation features also include tines coated with a
conductive material. The fixation features further include conductive
tines which are retractable. A defibrillation coil is optionally disposed
at the distal end of the lead in combination with the conductive tines.
