Medical implants have revolutionized healthcare, offering innovative solutions to a myriad of health conditions. From pacemakers to joint replacements, these devices have enhanced the quality of life for countless individuals worldwide.

However, while medical implants often provide significant benefits, they are not without risks.

One such risk is the potential for migration, where the implant moves from its intended location, leading to serious complications and harm.

In this article, we will discuss three notable cases where medical implants have been reported for migration, causing harm to patients.

Bard PowerPort

The Bard PowerPort, also known as a port-a-catheter, is an implantable venous access port utilized for administering medications, fluids, and blood products. It comprises a small reservoir (the port) connected to a catheter inserted into a vein, commonly in the chest or arm.

PowerPort is designed to provide reliable vascular access for patients undergoing treatments such as chemotherapy or long-term intravenous therapy. However, it has also been associated with migration-related complications.

According to TorHoerman Law, some individuals have alleged that the Bard PowerPort suffers from design flaws. These defects purportedly lead to elevated injection flow rates, exerting pressure on the plastic tubing and potentially causing the catheter to fracture.

Consequently, individuals may experience Port-a-Catheter migration symptoms. Fragments from the device migrate within the body, leading to adverse effects such as organ damage, infection, and blood clots.

Legal actions have ensued against the manufacturer in response to these claims. According to Consumer Notice, as of April 1, approximately 115 product liability lawsuits have been filed against the medical device company.

Essure Permanent Birth Control Device

Essure was marketed as a non-surgical, permanent birth control option for women. It consisted of two small metal coils inserted into the fallopian tubes, causing scar tissue to form and block the tubes, preventing pregnancy. However, from 2002 to 2023, the FDA received reports of thousands of women experiencing severe complications. Nearly 6,000 cases cited migration of the device.

This migration led to chronic pain, perforation of organs, and other serious health issues. Many women required surgical removal of the device to alleviate their symptoms.

In response to mounting complaints and safety concerns, Bayer, the manufacturer, withdrew Essure from the market in 2018, as per Drugwatch. Subsequently, in August 2020, Bayer settled about 90% of nearly 39,000 Essure-related lawsuits in the US for $1.6 billion. This signaled a significant legal and financial acknowledgment of the device’s adverse effects.

Hernia Mesh Implants

Hernia mesh implants are commonly used in surgical repair procedures to strengthen weakened or damaged tissue. The FDA underscores their widespread use across the United States. This is due to their effectiveness in reducing the recurrence of hernias, which are prone to developing again post-surgery.

Research and medical literature consistently validate the benefits of mesh in fortifying repairs and improving long-term outcomes for patients.

However, despite their widespread adoption and documented efficacy, these implants are not without risks. Migration of hernia mesh, though relatively rare, presents a significant concern.

When the mesh shifts from its intended position, it can trigger a cascade of complications. These range from chronic pain and inflammation to more severe issues like organ perforation.

The need for additional surgical interventions to address migration underscores the seriousness of these complications. A notable study from Oxford Academic highlights that 91% of patients require surgical intervention for mesh migration. This often culminates in organ resection to rectify the damage.


What are some examples of implanted medical devices?

Some examples of medical devices that can be implanted in the body include pacemakers, artificial joints, cochlear implants, intraocular lenses, catheters, and mesh implants.

How do you recognize if there’s a problem with your Port-a-Catheter?

If you suspect an issue with your Port-a-Catheter, signs such as difficulty accessing it during procedures may indicate a problem. Persistent pain around the implant site may also be a cause for concern.

What is medical device migration?

Medical device migration refers to the movement of an implanted medical device from its original position within the body to another location. This can occur due to various factors such as mechanical issues, tissue reactions, or surgical errors.

In conclusion, while medical implants have transformed the landscape of modern medicine, they are not immune to complications. Migration of implants can pose serious risks to patients, causing harm and necessitating additional medical interventions.

Understanding the potential risks associated with medical implants is crucial. Taking appropriate precautions can help minimize complications and ensure the safest possible outcomes for both healthcare providers and patients.
