Patent ID: 8795301

Claim:
An obstructing member for intermittently obstructing a pyloric valve, comprising: an occluding member having a low-profile configuration for trans-luminal delivery into a patient's stomach and a deployment configuration having a wider shape relative to the low-profile configuration, wherein the occluding member comprises an elongate structure extended longitudinally in the low-profile configuration; a locking mechanism coupled with the occluding member; a flexible tether having a length with a proximal end attached to the occluding member; and, a distal member attached to a distal end of the flexible tether and having an atraumatic shape, wherein the elongate structure forms a coiled or wound structure defining a plurality of turns which nest one adjacent to the other assuming a compact shape in the deployment configuration and whereby the occluding member encloses the locking mechanism and the occluding member is locked into its deployment configuration such that passage through the pyloric valve is inhibited or prevented by the obstructing member and where the obstructing member is further configured to intermittently contact and obstruct the pyloric valve.
