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 luminal organs, the method comprising the steps of:

providing an applicator including;

an end effector having two jaw members defining a pair of tissue-contacting surfaces and having a sealant-applying structure; and

at least one conduit configured for conveying a sealant to the sealant-applying structure;

positioning the jaw members of the applicator adjacent to and around a junction between the two luminal organs;

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

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

2. The method of claim 1, wherein the tissue-contacting surfaces of the applicator are curved along a majority of their length such that an intermediate portion of each of the pair of tissue contacting surfaces are spaced from one another when in an approximated position.

3. The method of claim 1, further comprising the steps of conveying a first part of a two-part sealant to the sealant-applying structure, via a first conduit;

and conveying a second part of the two-part sealant to the sealant-applying structure, via a second conduit.

4. The method of claim 1, wherein a transverse opening is defined between a first jaw member and a second jaw member when the jaw members are in an approximated position.

5. The method of claim 1, wherein at least one of the jaw members includes a generally arcuate shape.
