The study is an open-label, randomized, two-period crossover study. Up to one hundred and twenty (120) subjects with type 1 diabetes mellitus (T1DM) who use the MiniMed paradigm insulin pump, who meet the inclusion/exclusion criteria and who provide written Informed Consent will be enrolled in the study. The aim of the study is to examine the safety of the InsuPatch device in a home use setting. Mild Hypoglycemia,hyperglycemia and Adverse events will be compared between two phases of the study : 3 months with the use of the device and 3 months without the use of the device.

The primary objective of this study is to show that safety parameters are similar, when delivering insulin subcutaneously in subjects with type I diabetes using the InsuPatch device along with the Medtronic Minimed Paradigm insulin infusion pump and the Medtronic Minimed Quick-Set® infusion set compared to subcutaneous insulin delivered with the above mentioned equipment, without the InsuPatch device.

The participation of each subject in this study will be up to seven months and will include three phases: one week Run in phase , 3 months with device use and 3 months without device use. Study will include 4 clinic visits and bi weekly calls. During the entire study the subjects will be requested to preform at least 5 blood glucose self measurements and record results in a logbook.At each visit blood will be drawn for HBA1C test.

Inclusion Criteria:

1. Subject's age range 18- 65 years old (including 18 and 65 years old)
2. BMI: 18-35 kg/m2
3. Type 1 diabetes patients using a MiniMed Paradigm insulin pump for at least six months, who are administering insulin Lispro or Insulin Aspart and are using the Quick-set infusion set.
4. Patients with T1DM whose HbA1c values are at or below 9.5% (including 9.5%) and at or above 6% (including 6%).
5. Agree to sign consent form before any study-specific tests or procedures are to be performed.
6. Subject's completed at least 14 measurements during the Run-In Phase and readiness to continue the study with at least 5 blood glucose recordings per day and keep a logbook during the study period.
7. Subject readiness to use the InsuPatch, his comprehension of the study requirements and treatment procedures.
8. Willingness to comply with all specified follow-up evaluations.
