What this record shows

Medtronic accounts for 82.4% of it on its own, with 28 other manufacturers making up the rest. Reporting peaked in 2022 at $1,507 and has fallen 93.5% since, to $98 in 2025.
Across 211 payments — averaging $34.25 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
