Area of Science:

  • Urology
  • Medical Devices
  • Surgical Innovation

Background:

  • A novel electro-mechanical artificial urinary sphincter, ARTUS, has been developed.
  • ARTUS utilizes a unique sequential pressure mechanism to potentially mitigate urethral damage.

Purpose of the Study:

  • To assess the feasibility of implanting the ARTUS device in human cadavers.
  • To evaluate the surgical technique and basic operational parameters of the ARTUS device.

Main Methods:

  • ARTUS device implantation was performed in six human cadavers (3 male, 3 female).
  • Data collected included operation time, cuff size, wire length, and any complications.
  • Surgical technique was compared to the established AMS 800 device.

Main Results:

Related Experiment Videos

  • The ARTUS device implantation was found to be straightforward, utilizing a technique similar to the AMS 800.
  • Mean operation time was 20 minutes, with average cuff sizes of 4.5 cm (male) and 6 cm (female).
  • A larger subcutaneous pouch was required for ARTUS compared to AMS 800, and the study was preclinical.

Conclusions:

  • The ARTUS artificial urinary sphincter can be implanted with relative ease.
  • Surgical and technical approaches are comparable to the AMS 800, facilitating adaptation by experienced surgeons.
  • The study confirms the potential for ARTUS as a viable alternative in artificial urinary sphincter implantation.
