Abstract:
1. An endoscope sheath, said endoscope sheath comprising: a first sheet and a second sheet, said first sheet defining a first sheet distal end and an opposed first sheet proximal end, said first sheet also defining opposed first sheet first and second side edges extending between said first sheet proximal and distal ends, said second sheet defining a second sheet distal end and an opposed second sheet proximal end, said second sheet also defining opposed second sheet first and second side edges extending between said second sheet proximal and distal ends, said first and second sheets being sealed to each other adjacent said first and second sheet distal ends, first side edges and second side edges, said first and second sheets being unsealed from each other adjacent said first and second sheets proximal ends, said first sheet having greater optical clarity than said second sheet adjacent said first and second sheet distal ends, said first sheet having a first sheet elastic modulus that is larger than a second sheet elastic modulus of said second sheet adjacent said first and second sheet distal ends which biases a lens of an endoscope against the first sheet, when the endoscope is inserted into the endoscope sheath.
