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

1. A method of manipulating tissue during an endoscopically performed operative procedure with visualization of an internal operative site through an endoscope comprising the steps of

establishing a narrow portal to provide access to the internal operative site;

inserting an elongate device carrying absorbent material at a distal end thereof through the portal; and

contacting tissue at the internal operative site with the absorbent material carried at the distal end of the device to manipulate the tissue within the internal operative site.

2. A method of manipulating tissue as recited in claim 1 wherein the device includes a delivery tube and a deployment rod and the absorbent material is disposed at least partially within the delivery tube and has a proximal end attached to the deployment rod, said method further comprising the step of ejecting the absorbent material from the tube by moving the deployment rod.

3. A method of manipulating tissue as recited in claim 1 wherein the device includes an elongate rod attached to the absorbent material and said tissue contacting step includes grasping the rod to move the device to cause the absorbent material to contact and manipulate the tissue.

4. A method of packing during an endoscopically performed operative procedure with visualization of an internal operative site through an endoscope comprising the steps

establishing a narrow portal through the skin to provide access to the internal operative site;

inserting an elongate device carrying absorbent material at a distal end thereof through the portal to introduce the absorbent material to the internal operative site; and

positioning the absorbent material in contact with tissue at the internal operative site such that at least a portion of the absorbent material absorbs body fluids to facilitate the endoscopically performed operative procedure.

5. A method of manipulating tissue as recited in claim 4 wherein the device includes a delivery tube and a deployment rod and the absorbent material is disposed at least partially within the delivery tube and has a proximal end attached to the deployment rod, and said positioning step includes ejecting the absorbent material from the tube by moving the deployment rod.

6. A method of manipulating tissue as recited in claim 4 wherein the device includes an elongate rod attached to the absorbent material and said positioning step includes grasping the rod to move the device to cause the absorbent material to contact the tissue.

7. A method of performing an endoscopic operative procedure with visualization of an internal operative site through an endoscope comprising the steps of

establishing a narrow portal to provide access to the internal operative site;

inserting an absorbent material through the portal to the internal operative site;

positioning the absorbent material at the operative site such that at least a portion of the absorbent material absorbs body fluids; and

draining body fluids from the absorbent material for external collection.
