Abstract

Examples of invasive biosensor alignment and retention features and methods are described. One example biosensor includes a housing comprising: a first surface defining a first opening, and a second surface opposite the first surface, the second surface defining a second opening, the first and second openings defining a substantially unobstructed pathway through the housing; a biosensor wire partially disposed within the housing and having an exterior portion extending through the first opening; a hollow insertion needle positioned within the pathway and extending through the first opening, the hollow insertion needle at least partially encircling the biosensor wire; and a biosensor retention feature collapsible against the first surface of the housing, the biosensor retention feature encircling and contacting the hollow insertion needle.
