End effector assemblies and methods of manufacturing end effector assemblies for treating and/or cutting tissue

A surgical instrument comprising:

• a handle assembly;
• a shaft extending distally from the handle assembly;
• and
• an end effector supported at a distal end of the shaft and including first and second jaw members movable by the handle assembly between an open configuration in which the first and second jaw members are spaced apart from one another and a closed configuration in which the first and second jaw members are configured to grasp tissue therebetween, the first jaw member including:
• an insulative member;
• and
• a substrate formed as a single, integral component having first and second portions interconnected by a connector portion, the connector portion including first and second side portions interconnected by an arc-shaped portion, the connector portion configured to be removed before use of the jaw member such that the first and second portions are electrically insulated from one another.
