8. Arrange sterile drapes to allow visualization of the pelvic floor. This will help verify an appropriate motor
response to stimulation.
9. Ensure that the motor response of the toes and/or soles of the feet can also be observed.
Needle placement and test stimulation
Needle placement adjacent to the sacral nerve is assisted by anatomical landmarks and/or fluoroscopy. The placement
can be confirmed using test stimulation.
Note: For instructions on using the CP, refer to the Axonics Clinician Programmer Manual.
1. Using bony landmarks and/or fluoroscopy to guide placement, insert a foramen needle into the sacral foramen.
Keep an approximate 60-degree insertion angle relative to the skin. The nerve lies along the superior-medial
aspect of the foramen. (Figure 3)
Notes: The foramen needle has depth markings to aid in needle placement. The depth markings are 1 cm apart.
Caution:
The number of needle insertions into the foramen and the implant depth should be limited. Stop the needle
insertion at the point where the desired stimulation response usually occurs. This is usually at about 2.5 to 4.0
cm (1.0 to 1.5 in) in depth. The needle tip should be at the anterior surface of the sacral foramen for initial
stimulation. A low opening threshold of less than 2 mA indicates close proximity to the nerve. This threshold
should be the goal for initial needle placement.
2. Attach the clip end of the needle test stimulation cable to the non-insulated section of the foramen needle (just
below hub and above the triple dash mark on the foramen needle) (Figure 4).
