Three parts make up a working endoscope: the camera, light source, and biopsy channel. The channel allows passage of surgical instruments designed to cut and remove tissue.
As the endoscope articulates within the body, sometimes to angles exceeding 180 degrees, the biopsy channel may become twisted, compressed, or otherwise damaged. Repair can be expensive and time consuming.
Solution? A durable, but highly flexible endoscope channel extruded of PTFE. Reinforced with a 303 stainless-steel spring, and drape-coated with polyurethane, the low-friction passageway resists kinking, binding, and wear.

From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
Samsung's Galaxy line of smartphones used to fare quite well in the repairability department, but last year's flagship S5 model took a tumble, scoring a meh-inducing 5/10. Will the newly redesigned S6 lead us back into star-studded territory, or will we sink further into the depths of a repairability black hole?
