3B5-4-61135

Ottobock's 3B5-4-61135 is a microprocessor-controlled knee prosthesis variant in the company's broader C-Leg family. It is designed for everyday prosthetic use and combines waterproof IP68 protection with software-driven stance and swing control, along with user-selectable MyModes for activities such as cycling, stair use, slopes, and wet environments.

I do not have enough reliable model-specific information to identify a distinct launch or discontinuation year for the exact 3B5-4-61135 designation. In practice, this designation appears to be a configuration or order code rather than a standalone consumer-facing product name, so the available historical record is tied to the wider Ottobock knee platform rather than this exact variant.
