In the face down, side-lying, or sitting position (depending on the preference of the performing physician), a test injection of baclofen is initially administered to the spinal region of patients experiencing spasticity. If the patient benefits from this procedure, in the next session, a pump with the capability to automatically deliver baclofen to the spinal area in the desired amount for an extended period is permanently implanted into the patient's body.

During the placement of the permanent pump, the patient lies face down. The first step of the procedure involves inserting a catheter into the spinal area. Subsequently, a pump is placed in a suitable area on the side of the body, and the catheter's end is connected to the pump. The pump and catheter are entirely placed inside the body, beneath the skin, with no external contact. As the medication in the pump depletes (approximately every month), new medication is injected into the pump from the outside using a needle.

This procedure is performed under surgical conditions, monitoring all vital functions, with the patient under sedation and using an imaging scope for visualization.
