Overview of the Prostiva Therapy System
The Model 8934 Return Electrode (Figure 1-5) is placed on the
patient's lower back and connects to the Model 8930 RF
Generator. This connection completes the radio frequency
ablation circuit with the Model 8929 Hand Piece.

Refer to the Prostiva RF Therapy Kit Model 8929 Instructions for
Use for a detailed description of the return electrode applying,
connecting, and removing.
The return electrode has a self-adhesive surface that secures it to
the patient's skin. The return electrode provides a relatively large
electrode area. This helps to reduce the density of the
return-current flow from the hand piece to the patient's skin.
The return electrode also has a split-electrode design, which is
required for the radio frequency generator's "neutral-electrode
monitoring" (NEM) circuit. The NEM circuit monitors the
impedance between the electrode halves. This provides a
measure of how secure the electrode is attached to the patient's
skin. The return electrode's design and monitoring help to reduce
the risk of possible patient injury.
Warning: Do not use any return electrodes other than the
Medronic Model 8934. Use of other return electrodes may
result in less than optimum system operation, or possible
severe patient injury.
The Model 8934 Return Electrode is supplied in the kit that
includes the Model 8929 Hand Piece and the Model 6101 Tubing
System.
The return electrode is provided as a non-sterile medical device.
It is single-use only, and it should be disposed of in accordance
with local environmental requirements.
