Boston Scientific/Nalu Neurostimulation System

Boston Scientific agreed to buy the rest of Nalu Medical, whose small implant runs without a battery and is powered by a disc worn on the skin. The deal adds peripheral nerve stimulation to its spinal stimulation and nerve ablation pain business.

• About $533M upfront for the roughly 91% it did not already own; $600M on a 100% basis.
• Nalu expected over $60M of 2025 sales and 25%+ growth in 2026.
• COMFORT trial: 87% of patients had over 50% pain relief at 12 months.
• Boston Scientific had invested in Nalu since 2017.
