Sentimag / Magseed – Magnetic impalpable lesion localisation

In recent years, advancements in medical practices have offered more women diagnosed with breast cancer the opportunity to receive breast-conserving and lymph node-sparing surgery. At any stage, the target is to de-escalate the surgical radicality.

To ensure both oncologic safety and patient comfort, reliable marking of lesions and target lymph nodes is a prerequisite. However, many tissue markers encounter significant challenges, including:

  • unreliable detectability due to migration or low visibility in imaging
  • radiation exposure
  • not always suitable for long-term placement
  • not always suitable for each tissue type

As a result, patients can experience discomfort, such as unnecessary anxiety, physical pain and a suboptimal cosmetic outcome.

The Magseed marker has been specifically designed to overcome the challenges of other clip, reflector, tag, radioseed and wire markers. It enables a flexible patient treatment pathway – from placement of the marker until the day of surgery. Magseed promotes high oncologic safety, accurate tissue localisations and improved patient satisfaction, preventing unnecessary surgery and helping to reduce the extent of the required ones.

Magseed is used alongside the Sentimag system, a sensitive magnetic detector that locates the seed. The marker is deployed under ultrasound or X-ray guidance any time before surgery. Once in the operating room, the surgeon then uses the Sentimag system’s probe to precisely locate the Magseed, and thereby the lesion or lymph node in which the Magseed has been placed.

Magseed – benefits for clinicians and patients

  • Designed with the patient in mind – no radioactivity, reduced stress, less pain
  • Placed in any soft tissue – breast lesion, lymph node, etc.
  • Can be implanted for as long as needed – always reliably detectable by Sentimag
  • Smallest non-radioactive seed – ideal for lymph node placement
  • Decoupling of OR and radiology scheduling
  • Stays securely in place without migration from soft tissue
  • Very low re-excision rate for lesions (11 % averaged over multiple studies)
  • Magseed has been used in over 50,000 tissue localisations
  • Sentimag and Magseed are CE-marked and FDA-cleared for soft tissue
