Abstract

An insertion set for insertion through the skin of a patient includes at least one piercing member adapted to be secured to an insertion device and a set housing to be removable from the insertion device while maintaining installation of the insertion set. At least a portion of the at least one piercing member is insertable through the skin. The set housing is coupled to the at least one piercing member and is adapted so that it is shaped to fit an insertion device to orient the at least one piercing member for placement through the skin of at least a portion of the at least one piercing member at a predetermined angle relative to the skin to install the insertion set. The at least one piercing member is adapted to be retainable by the insertion device during removal from the insertion set.
