Device with removable projections

A naso-jejunal feeding device for insertion into a patient, said feeding device configured for dynamic movement into and through the patient's gastrointestinal tract toward an internal target site at the jejunum of the patient, the feeding device comprising:

• a hollow tubular member having a distal portion and an outer surface;
• a plurality of flaps disposed on said outer surface at said distal portion, said flaps projecting outwardly from the surface of the tubular member so as to engage an interior surface of the gastrointestinal tract and configured so as to promote ingress of the feeding tube toward said jejunum in response to peristaltic contractions;
• said flaps being formed of a material that dissolves when said tubular member is received in the gastrointestinal tract, said tubular member further comprising a plurality of apertures sized and shaped to permit fluid-like materials to enter the jejunum from an interior space of said tubular member.

A medical device configured for dynamic movement through a body canal toward an interior target site and removal therefrom, said device comprising an elongate tubular member having a plurality of distal projections disposed on an exterior surface thereof, said projections extending radially outwardly from the exterior surface of the tubular member a distance sufficient to engage an interior surface of the body canal during bodily contractions therein, said distal projections being configured so as to promote ingress of said device in response to said contractions, at least some of said projections being removable from said elongate tubular member under bodily conditions at said body canal for facilitating removal of said feeding device from said target site.
