Patent Images
1. An apparatus for applying sealant to a target tissue of a surgical site, comprising:
- a handle;
an end effector in operative association with the handle, the end effector including a first jaw member, a second jaw member and a sealant-applying structure, the first jaw member and the second jaw member each having a generally arcuate shape, wherein the sealant-applying structure is configured for applying sealant to the target tissue;
at least one conduit for conveying sealant to the sealant-applying structure in the end effector; and
wherein the arcuate shape of the first jaw member and the arcuate shape of the second jaw member define a transverse opening having a center for encircling the target tissue when the jaw members are in an approximated position, the sealant-applying structure including a first aperture on the first jaw member and a second aperture on the second jaw member, the first aperture and the second aperture being arranged for directing the sealant toward the center of the transverse opening;
further comprising side walls for confining sealant, each side wall including a first end operatively connected to the jaw member and a second end extending from the jaw member to come into contact with tissue when the end effector is in a closed condition;
wherein at least one of the jaw members comprises side walls for confining sealant, each side wall includes a first end operatively connected to the jaw member and a second end extending from the jaw member to come into contact with tissue when the end effector is in a closed condition.

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.
