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.

Claims

1. A multifunctional device for use in an endoscopically performed operative procedure in combination with portal sleeve means establishing communication with an internal operative site from external of the body and said device is introduced to the operative site through said portal sleeve means, said portal sleeve means comprising a structural sleeve having a lumen extending longitudinally entirely through said sleeve, said device comprising sponge means having a first configuration in a dry state prior to use to pass entirely through said lumen and a second configuration, different from said first configuration, in a wet state after absorbing body fluids at the operative site, said sponge means being straight in said first configuration and being curved in said second configuration to define a recess for receiving tissue such that said sponge means in said second configuration cups tissue at the operative site, and manipulator means having a distal end attached to said sponge means and extending through said sleeve to a proximal end adapted to extend external of the body, said manipulator means moving said sponge means in the body and being adapted to cooperate with equipment external of the body to fix the position of said sponge means in the body.

2. A multifunctional device as recited in claim 1 wherein said manipulator means includes a rigid member attached to said sponge means.

3. A multifunctional device as recited in claim 1 wherein said manipulator means is bendable to fix the position of said sponge means.

4. A multifunctional device as recited in claim 1 wherein said manipulator means includes a flexible member attached to said sponge means.

5. A multifunctional device as recited in claim 4 wherein said sponge means includes a distal end and a proximal end and said manipulator means includes a member attached to said proximal end of said sponge means to fix the position of said sponge means.

6. A multifunctional device for use in an endoscopically performed operative procedure in combination with portal sleeve means for establishing communication with an internal operative site from external of the body and said device is introduced to the operative site through said portal sleeve means, said portal sleeve means comprising a structural sleeve having a lumen extending longitudinally entirely through said sleeve, said device comprising sponge means having a first configuration in a dry state to pass entirely through said lumen and a second configuration, different from said first configuration, in a wet state for engaging tissue at the operative site, tubular manipulator means having a distal end attached to said sponge means and extending through said sleeve to a proximal end adapted to extend external of the body, tubular spine means disposed in said sponge means and a tubular connector communicating with said spine means and passing through said manipulator means, said manipulator means moving said sponge means in the body and being adapted to cooperate with equipment external of the body to fix the position of said sponge means in the body.
