System for delivering an anvil assembly to a surgical site
First Claim
1. An anvil assembly delivery system comprising:
- an anvil assembly including a center rod and an anvil head assembly secured to the center rod;
a flexible tube having a first end configured for oral insertion into a patient and a second end, the anvil assembly being connected to the second end of the flexible tube;
a retrieval suture connected to the anvil head assembly, the retrieval suture being positioned to extend from the anvil assembly in a direction opposite to the flexible tube; and
a spacer supported on the retrieval suture adjacent the anvil head assembly, wherein the spacer prevents the anvil head assembly from being approximated in relation to a shell assembly of a surgical stapling device into a firing zone to prevent firing of the stapling device when the spacer is clamped between the anvil head assembly and the shell assembly.

Abstract
An anvil assembly delivery system includes an anvil assembly having a center rod and an anvil head assembly pivotally secured to the center rod a flexible tube having a first end configured for oral insertion into a patient and a second end engaged with the anvil assembly, and a retrieval suture connected to the head assembly positioned to extend from the anvil assembly in a direction opposite to the flexible tube. The anvil assembly delivery system also includes a spacer suture tube positioned adjacent the anvil head assembly and defining a suture channel, which is supported on the retrieval suture and is dimensioned to prevent the retrieval suture from becoming trapped in the staple line of a stapling device. In an embodiment, the spacer is a suture tube defining a suture channel which receives the retrieval suture.
