Product description
Embozene® Microspheres: Precision Redefined for Superior Patient Outcomes
Welcome to the forefront of embolization technology with Embozene® microspheres. Designed to provide flexibility tailored to the uniqueness of each patient, these microspheres represent a leap forward in precision. Coated with Polyzene-F polymer, they are calibrated for precision, ensuring a strong correlation between microsphere size and the diameter of vessel occlusion (7).
Indications
The Embozene® microspheres are indicated for the embolization of:
- Hypervascular tumours
- Arteriovenous malformations
- Uterine myomas
- Hepatocellular carcinomas
- Benign prostatic hyperplasia (BPH)
- Tumours of the head, neck, torso and skeletal system
- Haemorrhage and trauma
- Preoperative reduction of bleeding, outside the central nervous system

Calibrated Precision: Size Matters for Optimal Vascular Closure
At the core of the Embozene® microsphere technology lies precise calibration. Each microsphere, meticulously crafted with ≥95% of the microspheres being within the specified size range (1), guarantees accurate targeting of the specific vasculature. This precision isn’t just a technical detail; it directly translates into clinical accuracy (8), minimizing the risk of off-target effects. Size-calibrated microspheres ensure optimal vascular closure (7, 9), reducing the likelihood of unintended embolization and potential side effects, enabling you to confidently perform superselective and targeted embolizations.
In comparison with other commercially available microspheres, the preceding graphs demonstrate the superior calibration along with the small and specific size ranges of the Embozene® microspheres (9, 10).

Patient-Centric Precision: Strength in Numbers
Due to their tight and uniform size distributions, more microspheres occupy the same volume as compared with a wider size range. For example, a sphere with a diameter of 300 μm occupies 27-times the volume of one 100-μm sphere, thus enabling more 100-μm spheres to occupy the same volume as one 300-μm sphere (11).

Embozene® microspheres excel in precise calibration, enabling the delivery of a greater number of small microspheres (≤100 μm) in the same volume and facilitate a targeted distribution within the tumor, ensuring consistent and precise spread for maximum impact (11). This deliberate sizing strategy, promoting a homogenous distribution within the tumor vascular net, contributes to enhanced tumor targeting. The optimal microsphere size improves overall treatment outcomes by delivering therapeutic effectiveness where it matters most (8, 13).
Reduced Side Effects, Enhanced Outcomes: Practical Patient Benefits
Reduced Side Effects: Calibrated precision minimizes unintended embolization, reducing the likelihood of side effects for patients.
Enhanced Tumor Targeting: Optimal microsphere size ensures targeted delivery to tumor vasculature, improving overall treatment outcomes.
Lower Procedural Risks: Calibration precision contributes to procedural accuracy, lowering risks and complications associated with embolisation.
Remarkable Biocompatibility for Seamless Integration
Low Inflammatory Reactions: Paving the Way for Patient Comfort
In oncology, managing inflammatory reactions triggered by embolic agents is crucial. Embozene® microspheres, with a PMMA hydrogel core and Polyzene-F shell, exhibit lower inflammatory reactions compared to other microsphere products (3, 4), ensuring a seamless integration into the body’s natural processes. The biostability and biocompatibility of the Embozene® microspheres without any animal-derived elements, ensure minimal inflammatory reactions, making it a strategic choice for healthcare professionals aiming for patient-centric care during embolic procedures (2, 3).
Reduced Revascularization Risk: Enhanced Patient Outcomes
Studies suggest that Embozene® microspheres due to their Polyzene-F coating, may showcase a lower incidence of revascularization associated with cytokine or chemokine production (14). This insight highlights the potential of Embozene® microspheres in managing inflammation and contributing to optimized patient outcomes.
