Primary Outcome Measures:
  • Safety [ Time Frame: 29 Days ] [ Designated as safety issue: No ]
    Assess safety during 12 hours of Vitala™ device wear with convex products by measuring the frequency of adverse events relating to the stoma (including gastrointestinal, stomal and surrounding skin events), and stomal vascularity.

  • Efficacy: [ Time Frame: 29 Days ] [ Designated as safety issue: No ]

    Restoration of Continence (absence of fecal leakage around the device) for 29 days of Vitala™ daily wear according to the following parameters:

    • Proportion of subjects with leakage over time.
    • Overall weighted leakage rate.
    • Proportion of subjects without leakage.
    • Self-rating of ability to restore continence.


Secondary Outcome Measures:
  • Efficacy [ Time Frame: 29 Days ] [ Designated as safety issue: No ]

    Vitala™ device will also be evaluated for the following efficacy parameters:

    • Security of the device.
    • Flange to flange security.
    • Device wear time.
    • Subject comfort.
    • Control of odor.
    • Control of noise due to flatus release from the stoma.
    • Ease of use of the device during application and removal.
    • Subject acceptance of the device.

Experimental: Convexity/Vitala
For all enrolled Subjects, STAGE 1 (Days 1 - 14 equals Convex Product Wear Period followed by, for those who successfully complete Stage I, weekly increases in wear time of the Vitala™ device beginning with 4 hours of daily wear per week (Days 15 to 21), followed by 8 hours of daily wear time per week (Day 22 to 28), followed by 12 hours of daily wear time (Days 29 to 43).
Device: Vitala

  • Is willing to remove and replace the skin barrier wafer after three days, more often if desired, during Stage 2.
  • Has a stoma that protrudes no more than 2 cm at rest (lying down on back).
  • Has demonstrated success in wearing a traditional pouching system. (Investigator judgment)
  • Is willing to participate in the trial for a total of 43 days.
  • Is willing to meet with the investigator for a total of 5 scheduled visits plus additional visits as deemed necessary by the investigator.
  • Has the ability to do complete self-care.

Exclusion Criteria:

  • Has known skin sensitivity to any component of the products being tested.
  • Has a skin rating of "2" or greater according to the Skin Rating Scale.
  • Has peristomal ulcerations, peristomal pressure necrosis, parastomal hernia, Caput Medusa or mucocutaneous separation.
  • Is receiving radiation in the area of the pouching system.
  • Is receiving chemotherapy other than a stable regimen of maintenance chemotherapy.
  • Requires a pouch belt while wearing Vitala™.
  • Requires a moldable skin barrier.
  • Has participated in a clinical study within the past 30 days.
