Endoluminal sleeve device (1) for internally lining a section of the GI tract, comprising a sleeve (2) configured for deployment inside a GI tract, the sleeve (2) having walls of a flexible material defining a sleeve lumen (3), a proximal end (4) defining a proximal lumen opening (5), and a distal end (6) defining a distal lumen opening (7), a tubular anchoring portion (8) forming said proximal lumen end (4) and defining anchoring seats (9) delimited each one by an annular collar (11) forming an opening through which adjacent tissue portions (12) can be pulled into the anchoring seats (9), expansion means adapted to act on the tissue portions (12) arranged in the anchoring seats (9) such that the tissue portions (12) expand to a dimension greater than the opening of the annular collar (11).
Endoluminal sleeve device (1) for internally lining a section of the GI tract, comprising:
Endoluminal sleeve device (1) according to any one of the preceding claims, in which the tubular anchoring portion (8) comprises elastic means (29) which bias the anchoring seats (9) permanently radially outward.
Endoluminal sleeve device (1) according to any preceding claim, in which the expansion means comprise one of an injectable swelling agent, sclerosant agent, plastic bead insert.
Endoluminal sleeve device (1) according to claim any preceding claim, comprising a plurality of mechanical latch members (18) which can be pierced through the tissue portions (12) trapped in the anchoring seats (9) and which have a shape such that two opposite end portions of the mechanical latch member (18) can protrude out of the tissue portion (12) and overlap with the annular collar (11) from an internal side of the anchoring portion (8).
