Abstract

Disclosed is gastric restrictor assembly. The gastric restrictor assembly includes a housing having a base portion, a waist portion and head portion. The gastric restrictor assembly further includes a base having a plurality of pins extending therefrom. The base is configured for being lockingly received within the housing. When the base is received in the housing the plurality of pins extend across the waist portion. The gastric restrictor assembly further includes a restrictor member configured to be received within the throughbore. The base may be releasably received within the housing. The waist portion of the housing may define openings configured for receiving suction therethrough. The base portion may define openings for receiving the plurality of pins therethrough. The head portion may define openings for receiving the plurality of pins. The waist portion may be configured to receive a portion of stomach wall thereagainst. The housing may be configured to be received within the stomach of a patient. The housing may further define a substantially hourglass figure.

Claims

1-18. -18. (canceled)

19. A method for restricting a portion of the digestive tract comprising the steps of:

positioning a gastric restrictor assembly within a portion of the digestive tract, the assembly including a housing having a base portion, a waist portion, and a head portion, the base portion, the waist portion and the head portion being of unitary construction and defining a throughbore, the assembly further including a base member having a plurality of pins extending therefrom configured to be received within the housing; and

retracting the base member within the housing.

20. The method of claim 19, where in the positioning and retracting steps are performed transorally.

21. The method of claim 19, wherein the portion of the digestive tract is a stomach.

22. The method of claim 19, further including the step of providing a restrictor member within the housing to restrict the throughbore.

23. The method of claim 19, wherein the housing includes a substantially hourglass figure.

24. The method of claim 19, wherein the gastric restrictor assembly further includes a restrictor member.

25. The method of claim 24, further including the step of positioning the restrictor member in the through bore of the housing.

26. The method of claim 21, further including the step of providing a vacuum to the housing to cause a portion of the stomach to engage the waist portion of the housing.

27. The method of claim 19, wherein the step of retracting the base within the housing includes extending the plurality of pins from the base portion, across the waist portion, and into the head portion.

28. The method of claim 19, wherein the step of positioning the gastric restrictor assembly is performed using a positioning device.

29. The method of claim 19, wherein the positioning device includes a tubular body having a proximal end, a distal operational end, and a shaft extending from the tubular body, the shaft being configured for retaining the base member distally relative to the housing.

30. The method of claim 29, wherein the step of retracting the base member within the housing includes retracting the shaft relative to the housing.

31. The method of claim 19, wherein the step of retracting the base member within the housing automatically locks the base member to the housing.
