Abstract
A feeding device configured for insertion into the gastrointestinal tract of a patient, and dynamic movement through the gastrointestinal tract toward the jejunum. The device includes an elongate tubular member having a plurality of distal projections disposed on an exterior surface thereof. The projections extend radially outwardly from the exterior surface of the tubular member a distance sufficient to engage an interior surface of the gastrointestinal tract during peristaltic contractions therein, and are configured to promote ingress of the device in response to the contractions. At least some of the projections are soluble under bodily conditions at the gastrointestinal tract, thereby facilitating removal of the feeding device.
