Abstract
An endoscope has an insertion tube with a nontapered or tapered dilator. The dilator may be inflated via a control handle connected to the insertion tube. The endoscope and insertion tube may be used to examine a patient and to relieve a blockage with the use of the insertion tube.
Claims25
An endoscope comprising:
- a control handle having controls for delivering at least one utility;
- an insertion tube connected to the control handle, wherein the insertion tube has a distal end and a proximal end;
- and
- an expandable dilator on a section of the insertion tube between the distal end and the proximal end.
1 more element
An endoscope comprising:
- a control handle having one or more actuatable switches to deliver one or more utilities;
- an insertion tube connected to the control handle, wherein the insertion tube defines a proximal end and a distal end;
- wherein the insertion tube has a first substantially uniform diameter from the proximal end to the distal end;
- and
- a sheath covering the insertion tube, wherein the outer diameter of a section of the insertion tube covered by the sheath may be increased to a relatively larger diameter by a utility controlled by the control unit expanding the elastic sheath.
2 more elements
A method for dilating a body lumen with an endoscope, the method comprising:
- intubating the body lumen with an endoscope having an insertion tube with an expandable outer diameter and dilating the body lumen by increasing the insertion tube's outer diameter.
A method for dilating a blockage in a body lumen with an endoscope having an insertion tube, the method comprising dilating the blockage with the insertion tube.
An endoscope comprising:
- an insertion tube having a proximal end and a distal end;
- and
- an expandable dilator located on the insertion tube, wherein the dilator may be expanded from a first position to a second position.
