The Multi-Shank LMA design is ideal for acute or chronic applications. Each shank can have up to 32 electrode sites, therefore multiple connectors may be needed. MicroProbes for Life Sciences may also employ the 36 contact Nano Omnetics connector, model A79022-001, which is also compatible with most headstage manufacturers.
You will need to specify the number of shanks (S) as well as the specifications associated with each prong. If no SS tube is required, which may be the case for chronic applications, then specify 0 for option (b).
