In a major antitrust battle over cardiac catheter markets, Innovative Health LLC sued Biosense Webster, Inc. for monopolization, attempted monopolization, and unlawful tying under the Sherman Act and California’s Cartwright Act. The case centered on Biosense’s CARTO 3 cardiac mapping system and its high-density mapping and ultrasound catheters. Innovative alleged Biosense tied clinical support to catheter purchases, blocked reprocessed competitors, and restricted hospital choices. On May 16, 2025, a California jury sided with Innovative on four counts, awarding $147,406,481 in damages, which are trebled by law to $442,219,443. The verdict underscores strict enforcement of antitrust rules in medical device markets and highlights the risks of exclusionary practices.
