Frequently Asked Questions

What is a medical device recall?

When a medical device violates FDA law, the manufacturer is obligated to take action by removing the product from the place where it is used or sold or they must correct the product. Products are recalled when they are found to be defective and don’t operate as intended or if they pose a risk to health. The FDA classifies recalls into three buckets:

Class I: A situation where there is a reasonable chance that a product will cause serious health problems or death.

Class II: A situation where a product may cause a temporary or reversible health problem or where there is a slight chance that it will cause serious health problems or death.

Class III: A situation where a product is not likely to cause any health problem, injury or wrongful death.

How do I find out if my device has been recalled?

The FDA keeps an up-to-date database of recalled medical devices. This database can be used to search for your device to see if it’s been recalled. Even if your device isn’t on the FDA’s recall list, it is very important that we address your injury right away. The team at Muller Brazil will notify the manufacturer and your care team about following legal options to get you compensated for your pain.

Let Us Help With Your Injury

DePuy Knee Replacement
The DePuy Attune knee replacement is experiencing an unusually high rate of early failure, causing serious harm to some of its recipients. Our product liability and defective medical device attorneys are investigating lawsuits on behalf of patients who’ve received a DePuy Attune Knee replacement system and have since suffered complications. DePuy’s knee replacement system has been linked to debilitating injuries in its recipients, many of which require revision surgery to remove or replace the implant. Patients have reported suffering pain from bearing weight, effusion (production and leaking of fluids in the knee) and a decreased range of motion, all within two years of their procedures. If you’re experiencing any of these symptoms after receiving a defective medical device, contact us today for a free consultation and legal advice. Symptoms of defective DePuy Knee Replacements include:
- Implant loosening and instability in the knee joint
- Unusual swelling around the joint (lining becomes inflamed, fluid builds up)
- Persistent pain (constant throbbing or pain, especially when in motion)
- Warmth or heat in the knee (normal post-surgery, but if it continues it could be a failed implant)
- Disassociation of the insert
- Shifting of the components
- Bone erosion or loss
- Muscle/nerve damage
- Infection
- Fracture/misalignment of device components/femur or tibia
- Device dislocation
- Tibial subsidence (caving/sinking in)
- Decreased range of motion
- Clicking or grinding sounds when walking
- Metal shedding debris
Sorin 3T Heater-Cooler
The Sorin 3T Heater-Cooler System, used during various types of heart and lung surgeries, can spread dangerous bacteria during the procedures causing serious infections, illnesses, and even death. Our firm is currently representing individuals who have suffered infections as a result of the Stockert 3T Heater-Cooler System. The Stockert 3T Heater-Cooler System made by LivaNova was recently linked to the spread of a bacteria called Nontuberculous Mycobacteria (“NTM”). NTM has been known to cause serious illnesses, including chronic lung infections in immunocompromised patients and can even result in death when left untreated. If you or a loved one underwent any operation in which a heater-cooler unit was used, you may be eligible for financial compensation. Sorin 3T Heater-Cooler System complications include:
- Fatigue
- Difficulty breathing
- Persistent cough or cough with blood
- Fever
- Pain

- Muscle or joint pain
- Night sweats
- Weight loss
- Abdominal pain
- Nausea
- Vomiting
- Infection (NTM)
- Sepsis
- Surgical Wound Infection
- Endocarditis
Hernia Mesh
Lawsuits involving hernia mesh medical devices claim the products are failing at a rate higher than expected, and causing additional surgeries, infections, bowel obstruction, organ damage, scar tissue and chronic pain. One of the big differences between using a mesh product and using sutures is that a mesh can migrate (move) or shrink, and then cause bowel perforations (holes or tears), organ damage, obstructions, and additional surgeries. Several hernia mesh products have been defectively designed and are causing unnecessary repairs and injuries that would not have occurred if a sutures or other medical equipment had been utilized. Contact our personal injury attorneys today if you’ve experienced complications from hernia mesh or mesh-related medical product. The following are the most predominant mesh-related side effects:
- Perforated intestines
- Perforated bowels
- Intestinal fistulae (an abnormal passage/connection between two organs)
- Bowel obstruction/resection
- Peritonitis (Inflammation of the abdominal wall membrane)
- Abdominal wall tear
- Abscesses
- Sepsis
- Ingrown mesh (into the abdominal wall, intestine, or other organs)
- Organ puncture
- Hernia recurrence
- Chronic pain
- Infection
Hip Replacement
Our attorneys are currently investigating potential hip replacement lawsuits against various manufacturers. Thousands of hip replacement lawsuits against medical device manufacturers have been filed after metal-on-metal hip replacements caused several complications. People who were promised durable, effective hip replacements ended up experiencing high rates of implant failure, pain and metal poisoning. Complications include the wearing down of the component material (which can loosen the implant), metal ions (e.g. cobalt and chromium) entering the bloodstream, or parts of the implant breaking off into the space around the implant which can cause soft tissue damage, pain and bone, muscle and nerve damage. If you or a loved one has experienced any of the complications listed above from a metal-on-metal hip implant, use our contact form below to get in touch with us today! Side effects of metal-on-metal hip replacements:
- Necrosis (premature death of body tissue) or soft tissue damage due to exposure to metal particles due to wear of the implant
- Elevated toxicity (cobalt and chromium) levels in the blood due to wear of the implant
- Pain in the implant area
- Clicking, popping, or grinding in the area of the hip implant
- Premature failure of the hip replacement
- Fractured hip bone
- Infection
- Metallosis (a putative medical condition involving deposition and build-up of metal debris in the soft tissues of the body)
- Tissue inflammation
- Loosening and lysis (slow breakdown)
- Fluid collections and cystic or solid masses around the joint
IVC Blood Clot Filter
Our law firm is currently representing clients who suffered injuries as a result of an IVC filter. Lawsuits involving the IVC Filter state the manufacturers of the device failed to warn patients and physicians of the increased risks of the filter breaking, and metal fragments moving through the blood, potentially damaging an organ. Attorneys argue that C.R. Bard (the manufacturer) hid the results of its own research which had found the filter dangerous, and even forged an employee’s signature on an FDA application in order to get approval. Our attorneys are committed to investigating and pursuing claims against all manufacturers of defective IVC filter products. These injuries require an experienced attorney - contact us immediately if you or a loved one have been injured! IVC Filter Complications:
- Device fracture (pieces of the device travel through the veins, causing internal injuries)
- Migration of the device resulting in perforation or puncture
- Organ puncture
- Infection
- Blockages causing swelling in the legs
- Increased risk of blood clots
Vaginal Mesh
If you had a vaginal or pelvic mesh (TVM) implant, also known as a pelvic mesh implant or bladder sling, and are suffering from painful, serious side effects after one or more revision surgeries, you are not alone. The team at Muller Brazil is currently investigating the potential for transvaginal mesh lawsuits. Complications involving transvaginal mesh devices have been reported in tens of thousands of women in relation to nine different transvaginal mesh manufacturers, including American Medical Systems (AMS), Boston Scientific, C.R. Bard, Inc., Covidien and Johnson & Johnson. Have you been injured by a vaginal mesh implant? Connect with us for a free case evaluation. The most common complications include:
- Bleeding
- Pain
- Nerve damage
- Vaginal scarring
- Infection

Knee replacement is a fairly common procedure, and unfortunately lawsuits from defective knee replacement devices are becoming just as common. The team at Muller Brazil is currently investigating the potential for lawsuits stemming from defective knee replacements against various manufacturers. Preparing to file a knee replacement lawsuit and be a very complicated venture. Our attorneys can help provide information on where to file a claim, whether or not you should join a potential class action suit, and how to obtain a possible legal settlement.

Complications from knee replacement surgeries include:
- Infection (of the surgical wound or within the joint)
- Bleeding into the knee joint
- Damage to nearby ligaments or arteries
- Nerve damage (resulting in numbness)
- Blood clots or pulmonary embolism
- Fractures (during or after surgery)
