The present invention relates to an anchor configured for
minimally-invasive implantation and sized to remain securely positioned
within at least a portion of the gastrointestinal tract of an animal. The
anchor includes a radial spring formed from an elongated resilient member
shaped into an annular wave pattern about a central axis. The anchor
defines a central lumen and provides an outward radial force, while
allowing for substantial flexure about its perimeter. The anchor is
generally removable, but can include fasteners, such as barbs, to further
secure it to the surrounding anatomy. In some embodiments, the anchor
includes a connector coupling a fixed portion to a removable portion.
Further, the anchor can be used to secure a medical device within the
body, such as a flexible sleeve within the intestine.
