Intragastric bag for treating obesity
First Claim
1. An intragastric device for the treatment of obesity, the intragastric device comprising:
- a non-inflatable bag comprising a substantially inelastic material disposed within the gastric lumen of a mammal, the bag comprising a constraining member; and
a plurality of intragastric members disposed within the bag, the intragastric members being sufficiently small to permit introduction of the intragastric members into the bag, wherein a sufficient number of the intragastric members are disposed within the bag to prevent the bag from passing through the mammal'"'"'s pylorus,wherein the intragastric members are enclosed within the bag by the constraining member.

Abstract
An apparatus and method comprising at least one intragastric member made of a digestive-resistant or substantially indigestible material that is introduced into a bag located in the gastric lumen of a mammal for the treatment of obesity. One or more intragastric members are loaded into a delivery tube in a partially compacted first configuration and delivered to an overtube. The overtube includes a proximal end, a distal end and a lumen configured to receive the intragastric members in the first configuration for delivery to the bag located in the gastric lumen wherein the intragastric member is expanded to a second configuration. The apparatus further comprises a constraining element engaged with the bag to secure the intragastric member upon delivery into the gastric lumen.

15. An intragastric device for the treatment of obesity, the intragastric device comprising:
-
a non-inflatable bag comprising a substantially inelastic material having a plurality of openings distributed throughout an outer surface of the bag to facilitate the passage of the gastric fluid into and out of an interior of the bag; a plurality of intragastric members that are sufficiently small to permit introduction of the one or more intragastric members into the bag, wherein when the plurality of the intragastric members are disposed in the bag, the bag is configured to prevent the intragastric device from passing through the mammal'"'"'s pylorus;
a delivery tube having a lumen, a proximal end and a distal end, wherein the plurality of the intragastric members are loaded between the proximal end and distal end of the delivery tube; and
an overtube comprising a proximal end, a distal end and a lumen configured to permit passage through the plurality of intragastric members. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23)
