Abstract
Disclosed are methods for performing endoscopy comprising directing a distal end of an endoscope to proximity of a portion of a surface of a bodily cavity; and directing a liquid-gas stream at a portion of the surface of the bodily cavity. Disclosed are also devices useful in endoscopy, comprising: an elongated body having a proximal end and a distal end; a nozzle at the distal end; a gas channel configured for conveying a gas from the proximal end to the nozzle; and a liquid channel configured for conveying a liquid from the proximal end to the nozzle, wherein the nozzle is configured to generate a liquid-gas stream directed in a specified direction from a gas conveyed by the gas channel and a liquid conveyed by the liquid channel.
Claims50
A device useful in endoscopy, comprising:
- a) an elongated body having a proximal end and a distal end configured for maneuvering said distal end into a bodily cavity;
- b) a nozzle at said distal end of said elongated body;
- c) a gas channel configured for conveying a gas from said proximal end of said elongated body to said nozzle;
- and
- d) a liquid channel configured for conveying a liquid from said proximal end of said elongated body to said nozzle simultaneously with conveying of said gas;
- wherein said nozzle is configured to generate a liquid-gas stream comprising a mist of particles of liquid in said gas directed in a specified direction from a gas conveyed by said gas channel and a liquid conveyed by said liquid channel, the directed liquid-gas stream sufficient for moving a resting object from a surface of a bodily cavity.
