Abstract: Briefly, a kinkless infusion set has a setting control that engages a curved or helical cannula to simultaneously rotate the helical cannula as the helical cannula is moved toward a patients skin and then under the patient's skin to position the curved or helical cannula to a desired depth and position. In one example, the helical cannula is set between 3 mm and 5 mm under the patient's skin. Also, the curved or helical cannula may have side ports to allow medicine to be presented over a larger area for more effective therapeutic treatment. In some constructions the patient rotates the setting control, and in other cases the patient may push, pull or translate the setting control.

Abstract: An infusion set has an insertion device that inserts a cannula and introducer needle fully into a patient, and then fully removes the introducer needle with one user motion. In some examples the insertion device does not permit partial insertion or incomplete introducer element removal.

Abstract: Briefly, an extended use infusion set is provided that substantially extends the therapeutic life of an infusion set, thereby increasing patient comfort, decreasing costs, and providing for increased efficacy for infused medicines and therapeutics. Generally, the extended use infusion set uses an insertion mechanism to position a cannula or needle at an initial depth and location for subcutaneous infusion of medication. At a later time, when the therapeutic effect of the medication has decreased below a threshold, the patient uses a reset mechanism to reposition the needle or cannula to a new depth and location. In this way, the therapeutic effect of the medication is reestablished, enabling the infusion set to be used effectively for a longer period of time. The infusion set also contemplates setting and resetting a biosensor.
