Apparatus and methods for endoscope assemblies having working channels with reduced bending and stretching resistance are disclosed. In one embodiment, an endoscope assembly includes a sheath having a body portion adapted to at least partially encapsulate an endoscopic insertion tube, and a working channel attached to the body portion and extending along at least a portion of the body portion. The working channel includes a component for reducing the resistance of the assembly to bending and stretching.

The intervertebral disc is avascular. With aging, calcified layers occlude the cartilaginous endplates, blocking the diffusion of nutrients and oxygen into the avascular disc. Under anaerobic condition, excessive production of lactic acid irritates nerves and further hinders transport of sodium sulfate essential for biosynthesis of the water retaining and load sustaining sulfated glycosaminoglycans. As the result of acid irritation and load shifting to facet joints, pain ensues. Through the pedicle, calcified endplate is punctured by a well-supported and elastically curved needle, injecting antacid to neutralize the lactic acid and enhance transport of sodium sulfate into the shielded discs between ilia. Disc filler or nutrients can also be injected through the curved needle into the degenerated disc.
