What is the chance of Pintuition Seed migration?


Smaller, radioactive iodine seeds have been shown not to migrate [1] and a previous version of the Sirius Pintuition device was associated with negligible migration (all <1mm) after an implantation duration of median 18 (13-29) days, N=5 [2]”.

Is the Sirius Pintuition seed compatible with MRI imaging?


The Pintuition Seed is labelled as MR conditionally safe; this means patients with a Pintuition Seed in situ can safely undergo an MR scan (under certain conditions), but this will lead to image artefacts around the Seed. The Pintuition Needle is not safe for use during MRI, so it is not safe to implant the seed under MR guidance. Please refer to the Instructions for Use for specific information.

Is the Pintuition Seed approved for use during neoadjuvant therapy and how does this impact MRI response evaluation?

Is the Pintuition Seed approved for use in the Axilla or Inguinal lymph nodes?

Yes, in the EU the Pintuition Seed is approved for use in any soft tissue lesion up to 180 days prior to removal. For the US the current indication is breast tissue. Please refer to your local Instructions for Use document for the complete indications for use.

How long in advance can the seed be placed?

Is the Sirius Pintuition Seed visible on my imaging system?



The Pintuition Seed is visible on the most common imaging modalities, including ultrasound and x-ray/mammography.

How is the transcutanuous detection experience with larger breasts and the Sirius Pintuition System?


The Pintuition Seed can be detected up to 50mm from the probe. Sirius recognizes the necessity of the functioning of the technique in larger breasts. In our clinical studies with Sirius Pintuition there was no selection on breast size and transcutaneous detection was succesful in all cases [1]. In post-marketing feedback, there have been no complaints on non-functioning transcutaneous detection.
