1. A gastric restrictor assembly comprising:
- a housing;
a valve assembly supported within the housing, the valve assembly defining a throughbore through the housing and being actuable to selectively adjust an area of the throughbore;
an attachment mechanism supported by the housing, the attachment mechanism having at least one fastening element and being actuable to move the at least one fastening element from a first position to a second position securing the gastric restrictor assembly to an inner wall of a lumen;
a first actuator supported on the housing and operatively associated with the valve assembly, the first actuator being positioned to be transorally actuable to operate the valve assembly to selectively adjust the area of the throughbore;
a second actuator supported on the housing and operatively associated with the attachment mechanism, the second actuator being positioned to be transorally actuable to move the at least one fastening element to the second position securing the gastric restrictor assembly to an inner wall of a lumen; and
wherein the at least one fastening element includes a plurality of arcuate hoops positioned about the housing, the plurality of arcuate hoops having engaging members formed thereon that are configured to engage a drive member to facilitate movement of the at least one fastening element between the first position and the second position.
