SYSTEM DESCRIPTION

The VAPR System is designed to provide soft tissue ablation (vaporization), contouring, cutting
and hemostasis of blood vessels during arthroscopic surgical procedures.

The components of the DePuy Mitek VAPR System (FIGURE 1) are individually described in
Section 4 of this manual:

• VAPR Generator

• VAPR Handpiece and Cable

• VAPR Electrodes

• VAPR, VAPR 3 Footswitch

• Power Cord (not provided)

Use only the DePuy Mitek Handpiece and Electrodes with this System.
