Abstract

A multifunctional device for insertion in an anatomical cavity through a narrow portal includes an expandable bladder, a body of fluid absorbing material carried by the bladder and a mechanism, which can be inflation or mechanical, for expanding the bladder. The device has a cross-sectional size in a compressed state with the fluid absorbing material in a dry state and the bladder contracted to facilitate insertion of the device through the portal. The fluid absorbing material is soft and expandable in a wet state upon absorption of body fluids in the anatomical cavity, and the bladder is movable via the expanding mechanism to move the device to an expanded state wherein the cross-sectional size of the device is increased. The bladder is movable to decrease the size of the device to facilitate withdrawal of the device from the anatomical cavity through the portal.

Claims

1. A device for introduction into an anatomical cavity through an endoscopic portal in endoscopic procedures comprising

an elongate member having a distal portion including a distal end for being introduced into the anatomical cavity through the portal and having a proximal portion including a proximal end for being disposed externally of the anatomical cavity;

an expandable bladder along said distal portion;

a body of fluid absorbing material carried by said bladder, said fluid absorbing material having a dry state prior to introduction of said distal end through the portal and an expanded, wet state upon absorbing body fluids after introduction of said distal end into the anatomical cavity; and

a spine disposed within said bladder and being mechanically movable from a first position to a second position to expand said bladder to increase the cross sectional size of said device after said distal end is introduced through the portal into the anatomical cavity and being mechanically movable from said second position to said first position to contract said bladder to decrease the cross sectional size of said device to facilitate withdrawal of said distal end through the portal.

2. A device for introduction into an anatomical cavity through an endoscopic portal in endoscopic procedures comprising

an elongate member having a distal portion including a distal end for being introduced into the anatomical cavity through the portal and having a proximal portion including a proximal end for being disposed externally of the anatomical cavity;

an expandable bladder along said distal portion;

a body of fluid absorbing material carried by said bladder, said fluid absorbing material having a dry state prior to introduction of said distal end through the portal and an expanded wet state upon absorbing body fluids after introduction of said distal end into the anatomical cavity; and

a spine disposed over said fluid absorbing material and being mechanically movable from a first position to a second position to expand said bladder to increase the cross sectional size of said device after said distal end is introduced through the portal into the anatomical cavity and being mechanically movable from said second position to said first position to contract said bladder to decrease the cross sectional size of said device to facilitate withdrawal of said distal end through the portal.

3. A device for introduction into an anatomical cavity through an endoscopic portal in endoscopic procedures comprising

an elongate member having a distal portion including a distal end for being introduced into the anatomical cavity through the portal and having proximal portion including a proximal end for being disposed externally of the anatomical cavity;

an expandable bladder along said distal portion;

a body of fluid absorbing material carried by said bladder, said fluid absorbing material having a dry state prior to introduction of said distal end through the portal and an expanded wet state upon absorbing body fluids after introduction of said distal end into the anatomical cavity; and

a spine disposed between said fluid absorbing material and said bladder, said spine being mechanically movable from a first position to a second position to expand said bladder to increase the cross sectional size of said device after said distal end is introduced through the portal into the anatomical cavity and being mechanically movable from said second position to said first position to contract said bladder to decrease the cross sectional size of said device to facilitate withdrawal of said distal end through the portal.

4. A device for introduction into an anatomical cavity through a narrow portal comprising

an elongate member having a distal portion including a distal end for being introduced into the anatomical cavity through the portal, a proximal portion including a proximal end for being disposed externally of the anatomical cavity and a longitudinal axis;

a plurality of pivotable members along said distal portion and being movable between a first configuration and a predetermined second configuration;

a body of fluid absorbing material carried by said pivotable members, said fluid absorbing material having a dry state prior to introduction of said distal end through the portal and a wet state upon absorbing body fluids after introduction of said distal end into the anatomical cavity;

a flexible membrane disposed over said pivotable members, said membrane being movable between a contracted position close to said longitudinal axis and an expanded position away from said longitudinal axis in response to movement of said pivotable members from said first configuration to said second configuration; and

a handle disposed at said proximal end of said elongate member and connected with said pivotable members for moving said pivotable members to said predetermined second configuration after said distal end is introduced through the portal into the anatomical cavity and for moving said pivotable members to said first configuration to facilitate withdrawal of said distal end through the portal, said device having a first cross-sectional size when said pivotable members are in said first configuration and a second cross-sectional size greater than said first size when said pivotable members are in said predetermined second configuration.

5. The device as recited in claim 4 wherein said fluid absorbing material has a first size in said dry state and expands to a second size greater than said first size in said wet state.

6. The device as recited in claim 4 wherein said body of fluid absorbing material is disposed around said pivotable members.

7. The device as recited in claim 4 wherein said pivotable members are movable to an intermediate configuration between said first configuration and said predetermined second configuration and said handle is operable to selectively move said pivotable members to said intermediate configuration, said device having an intermediate cross-sectional size larger than said first cross-sectional size and smaller than said second cross-sectional size when said pivotable members are in said intermediate configuration.

8. A device for introduction into an anatomical cavity through a narrow portal comprising

an elongate member having a longitudinal axis, a distal portion including a distal end for being introduced into the anatomical cavity through the portal and a proximal portion including a proximal end for being disposed externally of the anatomical cavity;

a flexible membrane along said distal portion and being movable between a compressed position close to said axis and an expanded position away from said axis;

a body of fluid absorbing material carried by said membrane, said fluid absorbing material having a dry state prior to introduction of said distal end through the portal and a wet state upon absorbing body fluids after introductions of said distal end into the anatomical cavity; and

a spine connected with said fluid absorbing material for moving said membrane to said expanded position after said distal end is introduced through the portal into the anatomical cavity and for moving said membrane to said compressed position to facilitate withdrawal of said distal end through the portal, said spine being movable to a normal, predetermined configuration when said fluid absorbing material is in said wet state to move said membrane to said expanded position.
