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.

At the Design News webinar on June 27, learn all about aluminum extrusion: designing the right shape so it costs the least, is simplest to manufacture, and best fits the application's structural requirements.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
