Endoscopic portal for use in endoscopic procedures and methods therefor
First Claim
1. An endoscopic portal for establishing communication with an anatomical cavity through a wall of the cavity comprising;
- an elongate tubular portal sleeve for insertion through the cavity wall and having an open distal end for positioning within the cavity and an open proximal end for positioning externally of the cavity; and
a valve assembly disposed adjacent said portal sleeve proximal end and including a bladder having a passage therethrough for permitting insertion of instruments of various sizes in said portal sleeve through said passage and means in said bladder for compressing said passage to cause said bladder to sealingly contact instruments inserted through said passage.

Abstract
An endoscopic portal includes a portal sleeve for insertion through a cavity wall and having an open distal end for positioning within the cavity and an open proximal end for positioning externally of the cavity and a valve assembly disposed adjacent the portal sleeve proximal end. The valve assembly includes a bladder having a passage therethrough permitting insertion of instruments of various sizes in the portal sleeve through the passage of the bladder. The bladder has means therein for compressing the passage to cause the bladder to contact the instruments inserted through the passage in sealing relation. The portal sleeve includes an expandable lumen allowing instruments and objects larger in size than the inner diameter of the portal sleeve to be passed therethrough. A method of inserting instruments through an endoscopic portal includes the steps of inserting an instrument through a passage of a bladder filled with compressible material adjacent an end of the endoscopic portal disposed externally of an anatomical cavity and compressing the passage with the compressible material to cause the bladder to contact the instrument in sealing relation to prevent undesired fluid flow through the endoscopic portal.

20. An endoscopic portal for establishing communication with an anatomical cavity through a wall of the cavity comprising;
-
an elongate tubular portal sleeve for being inserted through the cavity wall and having an open distal end for being positioned within the cavity and an open proximal end for being positioned externally of the cavity; and a valve assembly disposed adjacent said portal sleeve proximal end and including a bladder having a passage therethrough permitting instruments of various sizes to be inserted through said valve assembly, said bladder being filled with a compressible material to cause said passage to conform to the size of the instruments inserted through said valve assembly to prevent passage of fluid through said valve assembly. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of inserting an instrument through an endoscopic portal passing through a wall of an anatomical cavity including the steps of;
-
inserting an instrument through a passage of a bladder filled with compressible material adjacent a proximal end of the endoscopic portal disposed externally of the anatomical cavity; and compressing the passage with the compressible material to cause the bladder to contact the instrument in sealing relation.
