A cryogenic equipment manufacturer has been hit with dozens of lawsuits in federal court this week after one of its tanks in a San Francisco fertility clinic imploded in March 2018, reportedly compromising most of the 2,500 patient embryos and 1,500 eggs it housed.

Chart Inc., the tank manufacturer based in Ball Ground, Georgia, had predicted its product could fail if it had a cracked weld, causing the vessel to implode, as part of a list of more than a hundred possible failure modes in compliance with the European Union’s Medical Device Directive, according to the 21 lawsuits in the U.S. District Court for the Northern District of California surfaced on Law.com’s Legal Radar on Friday morning.
