Abstract

A cannula assembly for rotational fractional resection (RFR), comprising at least one cannula configured for rotational operation and enclosed in a depth guide configured to control an insertion depth of the at least one cannula. The depth guide includes a vacuum chamber configured to maintain vacuum to evacuate resected tissue generated by the RFR. A method determines histological factors at a target site, and determines fractional resection parameters based on the histological factors. The parameters include dimensionality of a fractional field, orientation of the fractional field, resection depth, and a vector of directed closure. The cannula assembly is configured to fractionally resect tissue according to the parameters, including applying a cannula array of the cannula assembly to the target site, and rotating at least one cannula of the cannula array to circumferentially incise and remove a plurality of skin plugs in the fractional field.
