Abstract
Abstract A packing device for use in endoscopic operative procedures is formed of an elongate strip of absorbent, preferably expandable material having a rigid, dry state of a size to permit passage through a narrow endoscopic portal to an internal operative site and having a soft wet state when body fluids are absorbed thereby such that the packing device exposes and isolates tissue to be treated and protects adjacent tissue at the operative site while, in the dry state, is sufficiently rigid to manipulate tissue. A method of packing an internal operative site during an endoscopically performed procedures includes inserting a rigid strip of absorbent, preferably expandable, material through a narrow endoscopic portal and positioning the strip of material at the operative site such that at least a portion of the strip of material absorbs body fluids to become soft and pliable.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
84 words
A method of packing during an endoscopically performed operative procedure with visualization of an internal operative site through an endoscope comprising the steps of establishing a narrow portal through the skin to provide access to the internal operative site; inserting a rigid strip of absorbent material through the portal; and positioning the strip of material at the operative site such that at least a portion of the strip of material absorbs body fluids to soften the material to facilitate the endoscopically performed operative procedure.
Claim 2
Independent Claim
84 words
A method of packing during an endoscopically performed operative procedure with visualization of an internal operative site through an endoscope comprising the steps of establishing a narrow portal through the skin to provide access to the internal operative site; inserting a rigid strip of absorbent material through the portal; and positioning the strip of material at the operative site such that at least a portion of the strip of material absorbs body fluids to soften the material to facilitate the endoscopically performed operative procedure.
Claim 3
Dependent Claim
44 words
A method of endoscopic packing as recited in claim 1 wherein said inserting step includes successively inserting a plurality of rigid strips of absorbent, expandable material through the portal and said positioning step includes successively positioning the strips of material at the operative site.
Claim 4
Dependent Claim
50 words
A method of endoscopic packing as recited in claim 2 and further comprising the steps of, prior to said inserting step, placing a sleeve through the skin to form the portal and, after said positioning step, removing the sleeve from the skin simultaneously with one of the strips of material.
Claim 5
Dependent Claim
45 words
A method of endoscopic packing as recited in claim 2 and further comprising the step of providing identifying means on each of the strips of material for identifying the strips of material outside of the body to allow individual movement of each strip of material.
Claim 6
Dependent Claim
24 words
A method of endoscopic packing as recited in claim 1 and further comprising the step of manipulating tissue with the rigid strip of material.
Claim 7
Dependent Claim
33 words
A method of endoscopic packing as recited in claim 1 wherein the strip of material is expandable with the absorption of body fluids and said positioning step includes expanding the strip of material.
Claim 8
Dependent Claim
45 words
A method of endoscopic packing as recited in claim 1 wherein the strip of material has a first rigid configuration when dry during said inserting step and a second configuration after the body fluids are absorbed by said strip of material during said positioning step.
