Abstract

See full text

A staple cartridge is disclosed that includes a first impedance sensing electrode and a second impedance sensing electrode. The first impedance sensing electrode is addressable to apply first energy to tissue positioned in a first zone. The second impedance sensing electrode is addressable to apply a second energy to tissue positioned in a second zone. A control circuit is configured to determine a thickness of the tissue positioned in the first zone based on the first energy and a thickness of the tissue positioned in the second zone based on the second energy. Advancement of a knife through an elongate slot of the staple cartridge is based on the determined thickness of the tissue in the first zone and the determined thickness of the tissue in the second zone.
