PERCUTANEOUS ENDOSCOPIC THERAPY
First Claim
Patent Images
1. An access device for an endoscopic procedure, wherein said access device comprises:
- (a) a tubular member comprising a proximal end region, a distal end region, an inflation chamber, an inner surface defining an inner diameter of said tubular member, and an outer surface defining an outer diameter of said tubular member, wherein said tubular member defines a lumen that extends from said proximal end region to said distal end region and is defined by said inner surface of said tubular member, and (b) an inflation port configured to allow gas to be introduced into said inflation chamber, thereby inflating said access device, wherein said outer diameter of said tubular member increases as said inflation chamber is inflated.

12. A method of performing an endoscopic procedure within a mammal, wherein said method comprises:
-
(a) inserting an access device into said mammal, wherein said access device comprises; (i) a tubular member comprising a proximal end region, a distal end region, an inflation chamber, an inner surface defining an inner diameter of said tubular member, and an outer surface defining an outer diameter of said tubular member, wherein said tubular member defines a lumen that extends from said proximal end region to said distal end region and is defined by said inner surface of said tubular member, and (ii) an inflation port configured to allow gas to be introduced into said inflation chamber, wherein said proximal end region is located outside the body of said mammal, and wherein said distal end region is located proximal to a target location within said mammal, (b) introducing gas into said inflation chamber via said inflation port, thereby inflating said inflation chamber, wherein said outer diameter of said tubular member increases as said inflation chamber is inflated, (c) introducing an endoscopic instrument into said mammal via said lumen to carry out said endoscopic procedure, (d) removing said endoscopic instrument from said mammal, (e) releasing gas from said inflation chamber via said inflation port, thereby deflating said inflation chamber, wherein said outer diameter of said tubular member decreases as said inflation chamber is deflated, and (f) removing said access device from said mammal. - View Dependent Claims (13, 14, 18, 19, 20, 21, 22, 23, 26, 28)
