The litigants in over 20,000 cases involving Ethicon Inc.’s transvaginal mesh have not been able to reach agreement on preserving the mesh taken out of the bodies of women, the plaintiffs said in court papers.

The plaintiffs don’t oppose having a preservation order put in place. But they “oppose the broad scope and ambiguity proposed by defendants in their motion, which requires plaintiffs to advise their healthcare providers to not only preserve explant material but to use ‘appropriate measures for doing so’ and ‘in a condition that enables defendants to do their own testing.’”
