Abstract
Systems, instruments, and methods are described in which a scalpet device comprises a housing configured to include a scalpet assembly. The scalpet assembly includes a scalpet array and one or more guide plates. The scalpet array includes a set of scalpets, and in embodiments the set of scalpets include multiple scalpets. The guide plate maintains a configuration of the set of scalpets. The set of scalpets is configured to be deployed from and retracted into the housing, and is configured to generate incised skin pixels at a target site when deployed. The incised skin pixels are harvested.
