Aquarius Pilot Study to Evaluate the New Axonics Trial System

May 11, 2026 updated by: Axonics, Inc.

Prospective, Multicenter, Single Arm Feasibility and Safety Study of the Axonics External Trial System (ETS-02)

Evaluation of the new Axonics External Trial System (ETS-02) in patients with overactive bladder (OAB) and/or fecal incontinence (FI).

Study Overview

Detailed Description

The trial system is used to determine if patients are responsive to sacral neuromodulation (SNM) prior to receiving the Axonics implantable neurostimulator (INS) which is approved for the treatment of OAB and FI. This study is evaluating the feasibility and safety of the new Axonics External Trial System (ETS-02) in patients with overactive bladder (OAB) and/or fecal incontinence (FI).

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Patients diagnosed with OAB and/or FI who are candidates for Axonics SNM (PNE) procedure
External trial system used evaluated whether patients with OAB or FI will be responsive to sacral neuromodulation.
A temporary electrode wire is passed through the S3 foramen with or without fluoroscopic guidance. The wire is then connected to an external pulse generator (EPG) and is worn for a trial period ranging from 3-7 days.
Other Names:
  • Basic or Advanced Trial
