This week was largely focused on QRB 2 preparation while keeping momentum on the technical side of the project. On the hardware planning side, we continued organizing the coagulation data collected from earlier builds so we can begin a clean comparison across prototypes. The hollow electrode configuration is now fully assembled at the distal interface, and the next step is to validate its performance once additional testing time is scheduled. We also confirmed that the latest PCB order has been placed with expedited shipping, which keeps our electrical integration timeline intact.

There were a few logistics items to track this week as well. We discussed material needs from Arthrex, particularly additional i90 components and the specific tubing interface required to mate with the pump line. We also followed up on CNC coordination for upcoming parts and began lining up the next round of handle and silicone mold work once the mechanical pieces are ready.

Next week the focus will be on deeper data comparison between builds, early integration work with the new clip based PCB approach, and preparing the next prototype variations. Team remains on schedule and in a solid position heading into the next phase.
