Hub for positioning annular structure on a surgical device
First Claim
1. An apparatus for forming an anastomosis between adjacent intestinal sections, the apparatus comprising:
- a) an anastomosis device including an anvil assembly having a shaft which is selectively attachable to a tubular body portion; and
b) a hub for locating an annular structure between the adjacent intestinal sections, the hub including a central sleeve defining a lumen for receiving the shaft of the anvil assembly therein, the central sleeve forming a connection portion for engaging a feature on the anastomosis device and connecting the hub to the device, the annular structure operatively connected to the hub and extending radially outwardly therefrom.

Abstract
An apparatus for forming an anastomosis between adjacent intestinal sections is provided. The apparatus includes an anastomosis device including an anvil assembly having a shaft which is selectively attachable to a tubular body portion; and a hub for locating an annular structure between the adjacent intestinal sections. The hub includes a central sleeve defining a lumen for receiving the shaft of the anvil assembly therein. The central sleeve forms a connection portion for engaging a feature on the anastomosis device and connecting the hub to the device. The apparatus further includes an annular structure operatively connected to the sleeve and extending radially outwardly therefrom.

9. An assembly for disposing an annular structure between adjacent intestinal sections, the assembly comprising:
-
a) an annular surgical stapling device, having an anvil assembly and a tubular body portion, the anvil assembly having an anvil member and an anvil shaft, the tubular body portion carrying a plurality of surgical staples in an annular configuration, the tubular body portion having a connection member disposed radially inward of the surgical staples, the anvil shaft of the anvil member being attachable to the connection member of the tubular body; and
b) a hub including a central sleeve defining a lumen therethrough for selectively receiving the anvil shaft therein, and an annular structure radially extending from the central sleeve, wherein when the hub is positioned on the anvil shaft the annular structure is concentrically located with respect to a longitudinal axis of the anvil shaft. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A method of disposing an annular structure between adjacent tissue sections, the method comprising the steps of:
-
a) providing a surgical stapling device including an anvil assembly and a body portion, the anvil assembly including an anvil member supported on an anvil shaft and the body portion carrying a plurality of surgical staples and a knife;
b) providing a hub for locating an annular structure between the adjacent tissue sections, the hub including a central sleeve defining a lumen which is configured and adapted for selectively receiving the shaft of the anvil assembly therein, and an annular structure operatively connected to the central sleeve and extending radially outwardly therefrom;
c) inserting the anvil assembly into a first tissue section; and
d) positioning the hub onto the anvil shaft such that the annular structure is concentrically located with respect to a longitudinal axis of the anvil shaft and such that the annular structure is positioned adjacent to the first tissue section. - View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25)
