Abstract
A flexible indwelling biosensor includes an elongated framework formed from a flexible material (e.g., a Nitinol strip) with a body portion, a sharp head, a distal end, and a proximal end. The flexible indwelling sensor also includes a biosensor (such as an interstitial fluid glucose sensor) integrated with the elongated framework with the biosensor having a sensing element disposed over (for example, on or suspended over) at least one of the body portion or sharp head of the elongated framework. Moreover, the sharp head is disposed at the distal end of the elongated framework and the sharp head and at least the sensing element of the biosensor are configured for insertion into a target site (for example, a subcutaneous target site).
