Overview

To determine time to set failure when the Convatec Inset II with Lantern technology (Convatec Lantern) infusion set with multi-slitted catheter is worn for up to 10 days

This is a pilot study to obtain preliminary data to determine the time to set failure when the Lantern infusion set is worn for up to 10 days. The study is not intended for registration purposes or to support a 510(k) submission. The study will be conducted at one site: Stanford University. This study will enroll 24 subjects (as per FDA approval) to establish the maximum length of Lantern infusion set wear when 80% of sets are still functional (excluding accidental "pull-outs"). Each participant will place the set and wear it for 10 days or until set failure and data will be collected on the cause of set failure. If a set is accidentally pulled out, it can be replaced by the subject. Failures are based on: 1. Presence of serum ketones with hyperglycemia 2. Unexplained hyperglycemia 3. Signs of infection at the infusion site 4. Pump occlusion alarm 5. Adhesive failure Since infusion set failures will occur after variable lengths of wear, regularly scheduled visits are unlikely to capture the day of an infusion set failure. Instead the subject will be taught how to insert the set, measure erythema and induration with a ruler marked in millimeters and to take a picture of the infusion site. Subjects will be instructed to text the study team when they remove their infusion set and to send a picture of the infusion site and measurements. If there is any evidence of an infection (≥10 mm of erythema or induration), they will be asked to come in that day for an unscheduled visit.

Inset II with Lantern TechnologyDEVICE

Each participant will insert the Inset II with Lantern technology and wear it for 10 days or until set failure and data will be collected on the cause of set failure. The infusion set will be used with their usual insulin pump.
