(A) Components of the CETE device, including skin anchoring pleats, a tension controller containing a tension line to be placed under a consistent strain or force, and bridge tubing. (B) When the DermaClose tension controller knob is turned clockwise, the constant force spring coils up until a clutch mechanism engages that prevents the pulling force from exceeding 11.7 N (1.2 kg). The constant force spring maintains its force to the spool of tension controller line as the wound edges are gradually approximated.
