have matching colors to avoid any confusion as to which ends should be tied together to form complete sutures anchor mount 720 is illustrated in fig7 a 7b as ring shaped anchor mount 720 however can have any of a variety of shapes particularly for the embodiments where the anchor mount is deformable such as being formed from suture threads material that does not substantially degrade in the gastric environment or the gastric wall for example fig7 c illustrates the anchor mount 720 that is deformed into a non circular elongated shape the anchor mount may be connected to the fastener second end such as via a fastener coupling 730 the fastener coupling may itself be a ring or other fastener that allows motion of the anchor ring such as a rotation type motion about one or more axis as desired the presutures and gastric cannula 10 may facilitate anchor mount that is at least partially embedded in the gastric wall fig7 c and that may extend out from the gastric wall this anchoring is straightforward reliable and automatically achieved as part of the removal of gastric cannula and attendant suturing of the wall defects by presutures 727 see also fig1 17 the anchor elements including anchor mount 720 may be formed from a.
