Ottawa – Health Canada has recalled several medical devices including one the agency warns could potentially cause death in the most vulnerable patients. That device is known as the OmniLab Advanced, and it’s typically used by people with sleep apnea — a condition where those affected stop and restart breathing while asleep. Several models of ophthalmic surgery procedure packs, 2 models of paracervical/pudendal kits from Medline Industries and Lp have also been recalled.
