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.

What is claimed is: 1. A subcutaneous infusion device, comprising: a site including a cannula extending from the site and configured to be introduced into a subcutaneous layer of skin of the patient; an adhesive portion including a first surface coupled to the site and a second surface including an adhesive configured to be coupled to the skin of the patient; and a release feature coupled to the adhesive portion, wherein the release feature assists the patient in removing the adhesive portion from the skin, and wherein the release feature is positioned between the adhesive portion and the skin and is configured to contact the skin, wherein the adhesive portion includes a visual indicator positioned on the first surface of the adhesive portion to assist the patient in locating the release feature. 2. The device of claim 1, wherein the release feature is a tab. 3. The device of claim 2, wherein the tab extends beyond an outer periphery of the adhesive portion. 4. The device of claim 1, wherein the release feature is a portion of the second surface of the adhesive portion whereat the adhesive has been voided. 5. A subcutaneous infusion device, comprising: a site including a cannula extending from the site and configured to be introduced into a subcutaneous layer of skin of the patient; an adhesive portion including a first surface coupled to the site and a second surface including an adhesive configured to be coupled to the skin of the patient; and a region coupled to the adhesive portion, wherein the region defines an exposed surface that is substantially free of adhesive so that, when the adhesive portion is applied to the skin of the patient, the region is positioned between the adhesive portion and the skin and the region contacts but does not adhere to the skin, and wherein the patient can grasp the region to remove the adhesive portion from the skin, wherein the adhesive portion includes a visual indicator positioned on the first surface of the adhesive portion to assist the patient in locating the release feature. 6. The device of claim 5, wherein the region is a tab. 7. The device of claim 5, wherein the adhesive portion is at least partially semi-transparent so that the patient can visually locate the region through the adhesive portion. 8. The device of claim 5, wherein the region is formed of sufficient rigidity so that the patient can feel the region through the adhesive portion.
