Abstract

An apparatus for applying sealant to a target tissue of a surgical site is provided. The apparatus includes a handle, conduit and an end effector. The handle has means configured and adapted for operating the end effector and dispensing biological sealant to the surgical site via the end effector. The conduit stores and/or carries sealant towards the end effector. The end effector is configured to clamp around a body organ or tissue and apply and confine biological sealant in a substantially uniform manner thereto.

Claims

1. A method of performing an anastomosis of two hollow organs, comprising:

providing an applicator including an end effector having two jaw members defining an open circle in a closed position and having tissue-contacting surfaces and dispensing apertures directed radially inwardly, and at least one conduit configured for conveying a material to the apertures;

positioning the jaw members around a junction between the two hollow organs;

approximating the jaws of the end effector to substantially surround the junction; and

applying the material to the junction between the two luminal organs via the end effector.

2. The method according to claim 1, wherein the material is selected from the group consisting of a sealant and an adhesive.

3. The method according to claim 2, wherein the material comprising a first material and a second material, the first material and second material forming a two part adhesive.

4. The method according to claim 1, further comprising the step of stapling the organs.

5. The method according to claim 1, further comprising disposing the material in a reservoir, the reservoir being in communication with the apertures.

6. The method according to claim 1, wherein approximating includes moving a handle member from a neutral position to an actuated position.

7. The method according to claim 6, wherein when the handle member moves from the neutral position to the actuated position, the material is pushed from a reservoir through a shaft and dispensed from the apertures.
