1. An endoscope having a proximal portion and a distal portion, said endoscope comprising:
- a tube having a distal end and a proximal end and having a lumen disposed from said distal end to said proximal end, and said tube also having an outer shielding layer disposed about an outside surface of said tube, an inner compressive layer and a middle conductive layer, said middle conductive layer being disposed between said outer shielding layer and about said inner compressive layer;
at least one tensile member disposed within said compressive layer, and said tensile member extending from said distal end to said proximal end of said tube;
an electronic chip positioned at the distal end of said tube, and said electronic chip being electrically connected to said middle conductive layer; and
,a lens positioned at the distal end of said tube-to be disposed adjacent to the electronic chip,wherein said inner compressive layer is a light transmitting material.
