IsoSeed® I-125

Loose Seeds with Excellent Visibility

IsoSeed® stands for two well-proven seed types to treat prostate cancer.

Eckert & Ziegler BEBIG provides seeds for both X-ray based and US based seed placement. Quality made in Germany combined with fast product delivery and reliable service.

Two Types of Seeds
At Eckert & Ziegler BEBIG, the customer can choose between two different sealed source models: I25.S17plus and I25.S06. Both seed models are visible under X-ray, fluoroscopy, CT, MR and ultrasound.

  • IsoSeed® I25.S17plus features a full size silver marker and has been designed for visibility under X-ray and fluoroscopic imaging. In addition, it enables MR imaging and opens new perspectives for postoperative planning.
  • IsoSeed® I25.S06 contains a thin gold marker within a ceramic carrier, diminishing artifacts and providing visibility in CT imaging.


Implantation with the Mick™ Applicator

IsoSeed® comes loose or in Mick™ Magazines. Each Mick™ Magazine has a capacity of 15 IsoSeeds. With the Mick™ Applicator, IsoSeed® can be implanted in any desired seed spacing distance, thus allowing a geometrically unrestricted seed distribution.

Quality Made in Germany

The seed production at Eckert & Ziegler BEBIG is performed at the manufacturing facility in Berlin, Germany. It operates under strict quality and regulatory standards. Each single IsoSeed® is required to pass rigorous quality inspections at every production stage before proceeding to the next step.
