Abstract
An ingestible device is provided. The ingestible device comprises a sink mechanism, for generating net influx of at least one constituent-of-interest present in a gastrointestinal tract of an individual, and a confining mechanism for confining the sink mechanism in a predetermined confinement.
Claims38
An ingestible device, comprising:
- (a) a sink mechanism for generating a net influx of at least one constituent-of-interest present in a gastrointestinal tract of an individual such that said at least one constituent-of-interest becomes absorbed in said sink mechanism;
- and
- (b) an outer housing comprising a confining mechanism for confining said sink mechanism inside said housing in a predetermined confinement, hence directing said net influx is into said confinement.
An ingestible device comprising:
- (a) a sink mechanism for generating an net influx of at least one constituent-of-interest present in a gastrointestinal tract of an individual;
- and
- (b) an outer housing comprising a confining mechanism for confining said sink mechanism inside said housing in a predetermined confinement, hence directing said net influx is into said confinement, wherein said sink mechanism is selected from the group consisting of a sink material and a sink device, wherein said sink material is for absorbing said at least one constituent-of-interest, wherein said sink material is selected from the group consisting of a high affinity sink material, a low affinity sink material and a combination of a high affinity sink material and a low affinity sink material, and wherein said high affinity sink material is selected from the group consisting of an antibody, whereby said constituent-of-interest is an antigen, a receptor whereby said constituent-of-interest is a ligand, a ligand whereby said constituent-of-interest is a receptor, an enzyme whereby said constituent-of-interest is an inhibitor, an inhibitor whereby said constituent-of-interest is an enzyme and a lectin whereby said constituent-of-interest is a saccharide.
An ingestible device comprising:
- (a) a sink mechanism for generating an net influx of at least one constituent-of-interest present in a gastrointestinal tract of an individual;
- and
- (b) an outer housing comprising a confining mechanism for confining said sink mechanism inside said housing in a predetermined confinement, hence directing said net influx is into said confinement, wherein said sink mechanism is selected from the group consisting of a sink material and a sink device, wherein said sink mechanism is for converting said at least one constituent-of-interest.
