Integrated subcutaneous sensor and infusion device, system and method

A medical device comprising:

• a base having a first surface configured to be secured to a patient's skin;
• a first insertable member secured to the base and having a length portion extending from the first surface of the base to a distal end of the first insertable member, for insertion through the patient's skin at an insertion site when the first surface of the base is secured to the patient's skin;
• a second insertable member configured to be secured to the base and having a length portion extending from the first surface of the base to a distal end of the second insertable member, for insertion through the patient's skin at the insertion site when the first surface of the base is secured to the patient's skin;
• wherein the first insertable member includes a sensor member for sensing a biological analyte corresponding to a biological condition;
• wherein the second insertable member includes an infusion cannula for infusing an infusion media;
• and
• wherein the distal end of the first insertable member and the distal end of the second insertable member are spaced apart by a first distance of at least 5 mm, for reducing interference of the infusion media from the infusion cannula with an operation of the sensor member.
