Abstract

A gastric restrictor assembly is provided. The assembly includes a housing defining a throughbore and having a base portion, a waist portion and head portion. The assembly also includes a pin holder including a plurality of pins extending therefrom. The pin holder is configured for being lockingly received within the housing. The plurality of pins extend across the waist portion when the pin holder is received within the housing.

Claims

1. A gastric restrictor assembly comprising:

a housing including a base portion, a waist portion and a head portion, wherein the base portion, the waist portion and the head portion are of unitary construction and the housing defines a throughbore;

a pin holder including a plurality of pins extending therefrom, the pin holder configured for being lockingly received within the housing, wherein the plurality of pins are supported by the pin holder to extend across the waist portion when the pin holder is received within the base portion of the housing.

2. The gastric restrictor assembly of claim 1, further including a restrictor member configured to be received within the throughbore.

3. The gastric restrictor assembly of claim 1, wherein the pin holder is releasably received within the housing.

4. The gastric restrictor assembly of claim 1, wherein the waist portion of the housing defines openings configured for receiving suction therethrough.

5. The gastric restrictor assembly of claim 1, wherein the base portion of the housing defines openings for receiving the plurality of pins therethrough.

6. The gastric restrictor assembly of claim 1, wherein the head portion of the housing defines openings for receiving the plurality of pins.

7. The gastric restrictor assembly of claim 1, wherein the waist portion of the housing is configured to receive a portion of stomach wall thereagainst.

8. The gastric restrictor assembly of claim 1, wherein the housing is configured to be received within the stomach of a patient.

9. The gastric restrictor assembly of claim 1, wherein the housing defines a substantially hourglass figure.

10. The gastric restrictor assembly of claim 1, wherein a first end of the housing includes ridges formed about an inner surface thereof.

11. The gastric restrictor assembly of claim 10, wherein the pin holder includes ridges formed about an outer surface thereof configured to engage the ridges formed on the housing when the pin holder is received within the throughbore of the housing.

12. The gastric restrictor assembly of claim 1, wherein the pin holder includes one or more locking tabs for selectively engaging the housing when the pin holder is received with the open distal end of the housing.

13. The gastric restrictor assembly of claim 1, wherein the waist portion defines a plurality of openings.

14. The gastric restrictor assembly of claim 1, wherein the head portion forms a substantially mushroom-shaped configuration.

15. The gastric restrictor assembly of claim 1, wherein the pins are disposed radially outward of the waist portion when the pin holder is received within the base portion of the housing.

16. A gastric restrictor assembly comprising:

a housing including a base portion, a waist portion and a head portion, the housing defining a throughbore;

a pin holder including a plurality of pins extending therefrom, the pin holder configured for being lockingly received within the housing, wherein the plurality of pins are disposed radially outward of the waist portion when the pin holder is received within the base portion of the housing;

wherein the restrictor is configured to capture a portion of gastric tissue radially inward of the pins and radially outward of the waist portion.
