Brief Summary
This study will evaluate the safety and effectiveness of how well blood glucose is managed when a participate wears the investigational SteadiSet™ Infusion Set (SteadiSet device) for up to 14 days post-insertion when compared to a Teflon Control infusion set.

Outcome Measures
Primary Outcomes (1)
Days of successful insulin delivery through the SteadiSet™ insulin infusion device versus a commercially available insulin infusion set
Successful insulin delivery period is defined as the days from infusion set insertion to either a removal of the infusion set due to normal use or removal of the infusion set due to set failure. a removal due to normal use or an infusion set failure, defined as: * The occurrence of hyperglycemia (glucose \>250 mg/dL or 14 mmol/L), not responsive to a pump bolus dose where response to the bolus is defined as a fall of at least 50 mg/dL or 2.8 mmol/L in blood glucose within one hour * The occurrence of any hyperglycemic episode (glucose \> 250 mg/dL or 14 mmol/L) not associated with acute intercurrent illness, but with a concurrent ketone level ≥0.6 mmol/L, or * Signs of infection at the infusion site (e.g. erythema or induration \>1 cm in diameter) at the investigator's discretion, or * Occurrence of a non-resolvable insulin pump occlusion alarm signal
up to 14 days
Study Arms (2)
Investigative Device - SteadiSet™" device with coil-reinforced soft polymer indwelling cannula
EXPERIMENTALParticipants are randomized into the investigational device (SteadiSet™) insulin infusion set group and then switched to a Commercially available infusion set (using a soft Teflon indwelling cannula) group. At the Day of Insertion (Day 0) clinic visit, study participants will insert (under supervision) the investigational infusion set. Upon completion of a wear period (after 14 days or sooner, in the event that infusion set change out has occurred), participants will be asked to insert a new set at home and thus start the next 14-day wear period. After two periods participants will return to the study site to cross over into the last two periods with the Control device infusion set. A total of four infusion sets will be studied in each participant, two Investigational Device infusion sets and two commercially available Teflon infusion sets.

- Participant is in generally good health, as determined by the investigator
- Participant is willing and able to individually complete written informed consent and agrees to comply with all study related testing and examinations
- Participant must be geographically stable (e.g., expects to be available and capable of returning for all study specified test and examinations) during the study period
- Participant has been diagnosed with T1DM for at least 12 months
- C-peptide \<0.6 nmol/L at screening
- Participant can provide a minimum of 14 days of insulin pump data to demonstrate pump use compliance
- Participant is willing to perform serum ketone measurements whenever the blood glucose is determined to be greater than 250 mg/dL (14 mmol/L) using a ketone meter and strips provided by the sponsor
- Participant has BMI in the range 18 - 35 kg/m2, both inclusive
- Participant has experience infusing insulin lispro or aspart for at least 6 months
- Participant has been using an insulin pump with commercially available infusion sets for at least 6 months
- Participant shows willingness to use CGM and successfully completes at least 1 week of successful trial with the Dexcom G6 (readings for at least 80% of the time can be retrieved)
- Participant has ability to understand and comply with protocol procedures and to provide informed consent
You may not qualify if:
- Participants routinely using steel insulin infusion sets who due to medical/skin conditions cannot switch to a Teflon set in the control ar
- Participants whose average total daily insulin dose exceeds 85 units/day (i.e. typically change insulin reservoirs more often than every 3.5 days on average
- Participants using any other medication than insulin to control their diabetes
- Participants who routinely change their commercial insulin infusion sets twice weekly or less often (wear time \> 3.5 days)
- Female participant is pregnant, planning to become pregnant, not using adequate method of contraception or nursing
- Participant has abnormal skin at intended device infusion sites (existing infection, inflammation, burns, or other extensive scarring)
- Participant has HbA1C \> 9.0% at screening
- Participant has documented history in last 6 months of severe hypoglycemia associated with cognitive dysfunction sufficiently severe to require third party intervention or a history of impaired awareness of hypoglycemia.
- Participant has a history of diabetic ketoacidosis in the last 6 months
- Participant has known cardiovascular disease considered to be clinically relevant by the investigator
- Participant has known arrhythmias considered to be clinically relevant by the investigator
- Participant has known history of: Cushing's Disease, pancreatic islet cell tumor, or insulinoma
- Participant has: Lipodystrophy, extensive lipohypertrophy, as assessed by the investigator
- Participant is undergoing current treatment with: Systemic oral or intravenous corticosteroids, monoamine oxidase (MAO) inhibitors, non-selective beta-blockers, growth hormone, thyroid hormones, unless use has been stable during the past 3 months
- Participant has significant history of any of the following, that in the opinion of the investigator would compromise the participant's safety or successful study participation: Alcoholism, drug abuse
