Lens holder option for implant during surgery

[TBNentwig]

Hi All,

I am curious what methods people are using to hold the GRIN lens while driving it into the brain. I'm familiar with the heat shrink serrefine method from the Resendez protocol, but I figured someone might have a newer, more clever design.

Alternatively, has anyone had luck using the lens holder designs from other providers such as the ONE core (neuroprobeamajiger), Doric, etc.?

Thanks for your insight.
