Kanso2 Retention Cases

It's a known fact that retention in Kanso2 for children is a problem since there is only 1 retention port at the bottom of the processor. We use a 3 strength magnet for our son Revaan and yet the processor keeps falling off. When it comes off the implant site, with the effect of gravity it just hangs and does not go back in place by itself (unliked original Kanso)

There are multiple hacks that people try, to keep the Kasno2 in place and make it go back by itself, you can find all of those here - https://drive.google.com/file/d/1LqulHRWPTuq0DLRxoOjae1N2P_QMw2-A/view?usp=sharing (I have been documenting and collating them since a long time)

We have been using a hack mentioned on the above sheet to make small holes on the cover of kanso2 and insert fishing line and attach wig clips, this has worked well for us and we see the avg coil offs coming down from ~30 to ~10 to 12 a day, and most importantly, the processors goes back in place by itself when a coil off happens (important with small kids like Revaan). But then, you are tampering with the case covers of devices which are so expensive and you are unsure if this should be done in the first place and what impact does on the long term functioning of the Kanso2 processors.

We recently came across a lady selling hard cases for Kanso2 in the US, they are heavily rated by a lot of parents who use them, as they assist a lot with retention of Kanso2. These cases however are very expensive for someone in India, will cost ~10,000 Rs for a pair including shipping making them not affordable.

We want to solve this problem and make this case accessible for Indian parents, so we started speaking with a few plastic case manufacturers in India, so that we can make Kanso2 processors stay in place on our kids heads for longer durations and even when they come off, they can swivel and go back in place by themselves.

In order to validate the problem from parents, we created the below form to collect feedback and results are for you to see, the form can be accessed here (or you fill the form directly below) - https://forms.gle/UJQqk4wRUDo32raX8

95.5% parents and users of Kanso2 processor indicated that they need help with retention of Kanso2

As a next step, we will continue to speak with manufacturers so that we can create cost effective cases that can be shipped across India to parents who need them.

We have also tried to reach out to Cochlear to inform them about the problem and ask them to share the number of parents who have been using Kanso2 in India so that we can collect everyone's feedback on the form above. But unfortunately Cochlear does not acknowledge the problem but rather ask us to keep increasing the magnet strength, which is not a solution given with young kids who are always hyperactive and unlike conscious adults, they would

run around aimlessly :)
jump and fall suddenly on the floor
roll over on the floor
lie down at random places

With the above activities, the processor is bound to come out irrespective of the strength of the magnet we can go for in kids. Plus higher strength magnet results in redness at the implant site.

Initially we will look to cover our investments and costs, once we break even, all proceeds from the sale of the cases will go towards https://lendaear.com. Looking forward to your support!
