Abstract
A gastric restrictor assembly for positioning within the digestive tract, e.g., stomach, of a patient to treat obesity is disclosed. The gastric restrictor assembly includes an attachment mechanism for attaching the assembly within a body lumen and a valve assembly for adjusting the diameter of a throughbore defined by valve assembly. The gastric restrictor includes first and second actuators which can be actuated transorally for operating the attachment mechanism and the valve assembly.

1-28. (canceled)
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 to a position securing the gastric restrictor assembly to an inner wall of a lumen;
- a first actuator supported on the housing and operatively associated with valve assembly, the first actuator being positioned to be transorally actuable to operate the valve assembly to selectively adjust the area of the throughbore;
- and
- 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 a position securing the gastric restrictor assembly to an inner wall of a lumen.
A gastric restrictor assembly according to claim 1, wherein the valve assembly includes a plurality of vanes which can be selectively repositioned transorally by the first actuator to change the area of the valve assembly throughbore.
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 to a position securing the gastric restrictor assembly to an inner wall of a lumen;
- a first actuator supported on the housing and operatively associated with valve assembly, the first actuator being positioned to be transorally actuable to operate the valve assembly to selectively adjust the area of the throughbore;
- and
- 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 a position securing the gastric restrictor assembly to an inner wall of a lumen,
- the throughbore having a configuration selected from the group consisting of a rectangular configuration;
- a square configuration;
- and an oblong configuration.
A gastric restrictor assembly according to claim 42, wherein the valve assembly further includes a first stationary member and a second movable member, the plurality of vanes being pivotally secured to the first stationary member, and the second movable member being movable between a first position and a second position to change the area of the throughbore.
