The methods include endoluminal delivery of the device.
Claims25
A method of placing a gastrointestinal implant device in a mammal, comprising the steps of:
- placing a gastrointestinal implant device in a container assembly, the implant device including an anchor and a floppy sleeve, the sleeve coupled to the anchor and folded into the container assembly;
- directing the container assembly, with the anchor and folded sleeve stored therein, into a mammalian gastrointestinal tract;
- removing at least a portion of the floppy sleeve from the container assembly by extending a portion of the floppy sleeve from the anchor and from container assembly to a location in the gastrointestinal tract that is distal relative to the assembly while the anchor is retained in the assembly;
- and
- subsequently removing the anchor from the container assembly and securing the anchor to a location in the gastrointestinal tract.
