Abstract
An infusion device including a site and a set for delivery of a substance to a patient. The site can include a cannula that is introduced into a subcutaneous layer of skin of the patient. The site is coupled to the skin of a patient by an adhesive portion including a release feature that allows the patient to remove the adhesive portion from the skin. The set can be coupled to the site by, for example, placing the set over the site and moving the set from an unlocked to a locked position. The substance can then be delivered through the set to the site, and from the site into the patient through the cannula. The set can be oriented at multiple rotational orientations with respect to the site, and can be coupled and uncoupled with the site multiple times.
