Study & Design

Arm && Interventions

Group	Intervention	Description
Convexity/Vitala	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).

Primary Outcome Measures

Name	Time	Method
Assessment of 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.	29 Days	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.
Assessment of the Efficacy in the Restoration of Continence (absence of fecal leakage around the device) for 29 days of Vitala™ daily wear according to the following parameters.	29 Days	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

Name	Time	Method
Assessment of the Efficacy of Vitala™ device will also be evaluated for the following efficacy parameters.	29 Days	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.
