To support your case, a lawyer would work with you to collect as much evidence as possible to prove that a medical device manufacturer’s negligence caused you harm and negatively impacted your health. This evidence commonly includes medical bills, medical records, photos and videos of any visible injuries, relevant x-rays or scans, testimony from witnesses or loved ones, and treatment information. Before you consult with a lawyer, it would be a good idea to collect as much documentation about any procedures related to your port-a-cath as possible.
