Rigidizing overtube with hemostasis valve

This device is a flexible tube, like an overtube, that can be made rigid. It works by having an inner layer of crisscrossing strands, such as a braid or mesh, which are locked in place when a surrounding bladder is pressurized. This action makes the tube stiff, and it also includes a hemostasis valve at one end.

Why it matters: Only two years have passed, so the inherent medical device regulatory and manufacturing challenges persist.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedCustom flexible tube, bladder, variable stiffness layer
