Abstract
An anvil assembly suitable for trans-oral delivery includes an anvil head configured to receive a suture that secures the anvil head in a delivery position and is separable from the anvil head following delivery of the anvil assembly. An anvil delivery assembly includes the anvil assembly, a delivery assembly secured to the anvil assembly, and a suture selectively secured to the anvil assembly for securing the anvil assembly in a delivery position and retrieving the anvil assembly.
Claims17
An anvil delivery system comprising:
- a delivery assembly;
- an anvil assembly selectively securable to the delivery assembly, the anvil assembly including:
- a center rod assembly selectively securable to the delivery assembly;
- and
- a head assembly pivotally secured to the center rod assembly between a first tilted position and an operative position;
- and
- a suture extending from the anvil delivery system through the head assembly and distally of the head assembly, wherein the suture retains the head assembly in the first tilted position.
A method of securing an anvil assembly in a first tilted position, the method comprising:
- receiving a first end of a suture through a first opening in a head assembly of an anvil assembly;
- receiving the first end of the suture through a bore in an adapter secured to a center rod assembly of the anvil assembly;
- receiving the first end of the suture back through a second opening in the head assembly;
- and
- tying the first end of the suture to a second end of the suture adjacent the head assembly.
A method of securing an anvil assembly in a first tilted position, the method comprising:
- receiving a first end of a suture through a first opening in a head assembly of an anvil assembly;
- receiving a second end of the suture through a second opening in the head assembly;
- receiving the first and second ends of the suture through a bore in an adapter;
- and
- securing the adapter to a flexible member such that the suture is secured within the bore.
