Magnetic Surgery®

Innovative technology that
makes surgery less invasive

What is Magnetic Surgery?

Magnetic Surgery is a medical technology used in various abdominal surgeries, including gallbladders, prostates, colorectals, and baratrics.

In bariatrics, for example, Magnetic Surgery is a safe and clinically-proven alternative to traditional bariatric surgery.

An external magnet is placed on your skin which controls a magnetic grasper inside your belly during surgery, eliminating a painful abdominal incision and resulting in less-invasive surgery.

Magnetic Surgery Benefits

Faster Recovery*

Magnetic Surgery patients spend less time in the hospital and return to work within 5 days of surgery on average.¹⁻²

Less Pain*

Patients experience less pain than traditional bariatric surgery patients.¹

Better Cosmetic Results

Look better with fewer incisions and less scarring.

*Based on retrospective, single-center study of 296 patients comparing magnetic liver retraction vs. a conventional liver retractor in bariatric surgery. Patients in the magnetic surgery cohort had significantly decreased 12-hour post-operative pain scores and hospital length of stay.

Hear from Real Patients

“I felt great after surgery and was walking the same day without assistance. I didn’t even feel like I had anything. I have lost nearly 100 pounds since then.”

Am I a Candidate?

Eligibility for Magnetic Surgery is based on your body mass index (BMI). Use the calculator to determine your BMI.

If your BMI is ≥ 35, or if your BMI is between 30 and 35 and you have type 2 diabetes or have not achieved substantial weight loss with nonsurgical methods, you may be a candidate.

    The Levita Magnetic Surgical System is indicated to grasp and retract the liver in bariatric procedures to facilitate access and visualization of the surgical site in patients with a body mass index(BMI) of 20-60 kg/m2. As with any surgery, there are risks associated with Magnetic Surgery procedures, including infection, injury to tissue and/or the abdominal wall, or the need for extended or additional surgery. In clinical trials, the only device-related adverse event reported was mild bruising (petechiae)¹⁻². Magnetic Surgery procedures are contraindicated for patients with pacemakers, defibrillators, other electro medical implants and/or ferromagnetic implants. Consult your physician to discuss the risks and benefits to determine if Magnetic Surgery is right for you.
