Multifunctional devices for use in endoscopic surgical procedures and methods therefor
First Claim
1. A multifunctional device in combination with an energy transmitting probe for transmitting energy to anatomical tissue for use in an endoscopically performed operative procedure of the type where a narrow portal is established to provide access to an internal operative site and said device is introduced to the operative site through the narrow portal, said energy transmitting probe including an electrical energy transmitting probe and said multifunctional device including sponge means for absorbing body fluids at the operative site and passage means extending entirely through said sponge means and receiving said electrical energy transmitting probe for treating tissue at the operative site.

Abstract
A multifunctional device for use in an endoscopically performed operative procedure of the type where a narrow portal is established through the skin to provide access to an operative site and the multifunctional device is introduced to the operative site through the narrow portal. The multifunctional device is formed of an absorbent material, preferably expandable, having a substantially rigid dry state prior to introduction to the operative site and a soft, flexible wet state after absorbing fluids. The absorbent material can be formed with a spine therein of either a continuous or a discontinuous, segmented construction, and the spine can be branched and tubular or solid. The absorbent material can have portions or segments thereof expandable to different sizes to produce rounded protuberances to facilitate manipulation at the operative site and can have predetermined, non-straight configurations in the wet state, the predetermined configurations being controlled by the spine in the absorbent material or the method of forming the absorbent material. The multifunctional device can have a passage therethrough to accommodate laser, electrosurgical, biopsy or culturing instruments.
