Hydraulic, adjustable substitute sphincter system for male stress urinary incontinence

Treatment of male stress urinary incontinence still presents a significant challenge, particularly after radical prostatectomy.  The ATOMS System combines a range of features to provide an effective, patient-friendly means of managing all grades of SUI.

Substitutes sphincter function

  • The suburethral substitute sphincter cushion is located in the middle of the mesh fixation tape and is filled via the port-catheter connection after the operation.
  • This cushion ensures a gentle, evenly-distributed pressure on the bulbospongiosus muscle. Pressure on the urethra is kept to a minimum and the risk of urethral erosion is significantly reduced.


  • There is no surgical reintervention required to adjust the system, the treating physician can simply alter the volume of liquid in the cushion via the access port.
  • Patient-specific adjustment to effect a change in continence status is possible at any time, even in the long-term.

Four-point fixation

  • The integrated mesh arms are drawn back around to the middle of the implant to secure the system in place. This eliminates the need for any fasteners or screws, and ensures a symmetrical, 4-point auto fixation.

Hydraulic operation

  • ATOMS is made up entirely of components that function hydraulically, thereby saving patients from the difficulties caused by defects which may occur in mechanical components months or years after the implantation.


  • ATOMS provides effective treatment for mild to severe stress urinary incontinence, even after radiotherapy.
  • Patients can urinate freely without having to activate a mechanical component. This means the system is also suitable for patients suffering from dementia, or whose cognitive skills may be expected to regress over time. Patients with joint pain (e.g. gout) also benefit from not having to operate the system manually.

Proven long-term effectiveness¹

The results of the latest clinical article demonstrates the long-term safety and efficacy of ATOMS in the treatment of incontinence in men, following invasive prostate treatment.

  • Up to 7 years follow up data
  • A multinational retrospective study of 287 men implanted with ATOMS - 1st generation to the 3rd generation of the device included
  • 89% of patients treated had moderate or severe SUI
  • Median follow up of 31 months with a range of 10 to 54 months
  • Overall success rate of 90% and dry rate of 64% after 3 post-op adjustments
  • 0% urethral erosion rate
  • Despite 25% of the cohort having received radiotherapy treatment, the ATOMS delivered overall results of an 81% dry rate and 92% overall success rate*
