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. In alternate aspects, the working channel may include a cut, a gap, a sliding portion, or an expansion section. Endoscope assemblies having a working channel in accordance with the invention advantageously reduce the articulation and stretching resistance of the assembly during articulation of the endoscope assembly. Also, because the axial forces (tension and compression) within the working channel are reduced, the working channel can be fabricated out of a relatively hard, inelastic material, thereby reducing the friction within the working channel and improving the physician's ability to perform a medical procedure.

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.

A method and apparatus for balancing power plane pin currents in a printed wiring board (PWB) provides for reduction in pin counts required for power plane (including ground plane) connections and/or reduction in requirements for connector current handling per pin. One or more slots is introduced in the metal layer implementing the power plane that alter the current distribution in the power plane. The per-pin current profile for connector pins connected to the power plane is equalized by tuning the length of the slot(s). The slots may be dashed or made internal to the power plane metal layer to avoid weakening the metal layer for laminated multi-layer PWBs and may be shaped around a connector end when the power plane pin allocation is not uniform at the connector ends. The resulting equalization reduces either pin count required for carrying the power plane current or reduces connector pin current requirements.
