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. In combination, a portal sleeve and a packing device for packing an internal operative site within the body of a patient in an endoscopically performed operative procedure where a narrow portal provides access to the operative site, the combination comprising

an elongate structural portal sleeve for establishing communication with the operative site from externally of the body when said portal sleeve is disposed in the narrow portal, said portal sleeve having a distal end for being disposed within the body, a proximal end for being disposed externally of the body and a lumen between said distal and proximal ends;

and

a packing device comprising a delivery tube for being received in said lumen, an elongate strip of absorbent material capable of absorbing fluid, said strip of material having a dry state prior to absorbing fluid and a wet state when fluid is absorbed by said strip of material, said strip of material being rigid and stiff in said dry state and being soft and flexible in said wet state, said strip of material being disposed in said delivery tube in said dry state, and a rod attached to said strip of material and extending externally of the body when said delivery tube is received in said lumen, said rod being movable distally and proximally relative to said portal sleeve while remaining attached to said strip of material to force said strip of material from said tube and said portal sleeve to introduce said strip of material at the operative site and to manipulate said strip of material at the operative site once said strip of material has been forced from said portal sleeve.

2. The combination device as recited in claim 1 wherein said strip of material has a rod-shaped configuration in said dry state.

3. The combination as recited in claim 1 wherein said strip of material has a corrugated configuration in said dry state.

4. The combination as recited in claim 1 wherein said strip of material expands when fluid is absorbed thereby.

5. The combinaiton as recited in claim 1 wherein said strip of material has a proximal end and said rod includes a portion passing centrally through said strip of material and a portion extending from said proximal end of said strip of material to be disposed externally of the body when said delivery tube is received in said lumen.

6. In combination, a portal sleeve and a packing device for packing an internal operative site within the body of a patient in an endoscopically performed operative procedure where a narrow portal provides access to the operative site, the combination comprising

an elongate structural portal sleeve for establishing communication with the operative site from externally of the body when said portal sleeve is disposed in the narrow portal, said portal sleeve having a distal end for being disposed within the body, a proximal end for being disposed externally of the body and a lumen between said distal and proximal ends;

and

a packing device comprising a delivery tube for being received in said lumen, an elongate strip of absorbent material capable of absorbing fluid, said strip of material having a dry state prior to absorbing fluid and a wet state when fluid is absorbed by said strip of material, said strip of material being rigid and stiff in said dry state and being soft and flexible in said wet state, said strip of material being disposed in said delivery tube in said dry state, a rod attached to said strip of material and extending externally of the body when said delivery tube is received in said lumen, said rod being movable distally and proximally relative to said portal sleeve while remaining attached to said strip of material to force said strip of material from said tube and said portal sleeve to introduce said strip of material at the operative site and to manipulate said strip of material at the operative site once said strip of material has been forced from said portal sleeve and means for constraining said strip of material to assume a predetermined configuration in said wet state upon absorption of fluid by said strip of material after introduction of said strip of material at the operative site.

7. A packing device for packing an internal operative site in an endoscopically performed operative procedure where one or more narrow portals provide access to an operative site in the body, said packing device comprising a plurality of elongate strips of absorbent material capable of absorbing body fluids, said strips of material each having a dry state prior to absorbing body fluids and a soft, flexible, expanded wet state when body fluids are absorbed by said strips of material, said strips of material each having a lateral cross sectional size in said dry state to permit passage of said strips of material through the one or more narrow portals and each having a length to permit positioning of said strips of material at the operative site, and indicia carried by each of said strips of material for being disposed externally of the body for distinguishing said strips of material from one another externally of the body.
