There is about year and a half, since Klystra's Double Balloon Retention nozzles (F2-S, F3-S) is no longer available.
I've wrote them on web-form and email 3 or 4 times. Got no response.
Information on klystra.com is completely outdated.
And couple of days ago my F2-S got broken.
So i think, this is the real Double Balloon Crisis 😢
I've tried to find another options, but there are insufficient for me:
There is a low cost/quality products under "CleanStream" trademark,
and "Rusch" products available from medtech3000.de:
Also there is another concept of retention nozzle:
And there is a question:
Are you know any information about resuming production of klystra's double balloon,
or any other alternatives or ideas?
