Payments from drug & device makers
What this record shows
This record is dominated by royalties or licence payments: $416,309 of the $431,656 with a category attached, or 96.4%. Merit Medical Systems Inc accounts for 99.9% of it on its own, with 4 other manufacturers making up the rest. 2025 is the largest year on record at $155,227, more than ten times the $121 reported in 2019. Among vascular & interventional radiology clinicians in CT with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 57 payments — averaging $7572.91 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.
