1. A method for restricting a portion of the digestive tract comprising:
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.
2. The method of claim 1 , wherein positioning the gastric restrictor assembly and retracting the base member are performed transorally.
3. The method of claim 1 , wherein the portion of the digestive tract is a stomach.
4. The method of claim 1 , further including providing a restrictor member within the housing to restrict the throughbore.
5. The method of claim 1 , wherein the housing includes a substantially hourglass figure.
6. The method of claim 1 , wherein the gastric restrictor assembly further includes a restrictor member.
7. The method of claim 6 , further including positioning the restrictor member in the through bore of the housing.
8. The method of claim 1 , wherein retracting the base member within the housing automatically locks the base member to the housing.
9. A method for restricting a portion of the digestive tract comprising:
positioning a gastric restrictor assembly within a stomach, 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;
providing a vacuum to the housing to cause a portion of the stomach to engage the waist portion of the housing; and
retracting the base member within the housing.
10. A method for restricting a portion of the digestive tract comprising:
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 by extending the plurality of pins from the base portion, across the waist portion, and into the head portion.
11. The method of claim 10 , wherein positioning the gastric restrictor assembly and retracting the base member are performed transorally.
12. The method of claim 10 , wherein the housing includes a substantially hourglass figure.
13. The method of claim 10 , wherein the gastric restrictor assembly includes a restrictor member and positioning the restrictor member in the throughbore of the housing.
14. The method of claim 10 , wherein the portion of the digestive tract is a stomach and further includes providing a vacuum to the housing to cause a portion of the stomach to engage the waist portion of the housing.
15. A method for restricting a portion of the digestive tract comprising:
positioning a gastric restrictor assembly within a portion of the digestive tract using a positioning device, 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, 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; and
retracting the base member within the housing.
16. The method of claim 15 , wherein retracting the base member within the housing includes retracting the shaft relative to the housing.
17. The method of claim 15 , wherein positioning the gastric restrictor assembly and retracting the base member are performed transorally.
18. The method of claim 15 , wherein the housing includes a substantially hourglass figure.
19. The method of claim 15 , wherein the gastric restrictor assembly includes a restrictor member and positioning the restrictor member in the throughbore of the housing.
20. The method of claim 15 , wherein the portion of the digestive tract is a stomach and further includes providing a vacuum to the housing to cause a portion of the stomach to engage the waist portion of the housing.
