Reduced non-target embolization & Better delivery with SeQure® innovative microcatheter

introduction

 
Current shortcomings of catheter-directed  embolotherapy with use of particulate agents:
- Non-target embolization
- Incomplete devascularisation


Non-target embolization

      - In which IR-procedure?

                   - Chemoembolization liver
                   - Prostate arter embolization
                   - Uterine fibroid embolization
                   - Bronchial artery embolization
                   – ….

5% off target distribution (脱靶分布) in the cholecystic wall  Potential side effects such as cholecystitis or pancreatitis
Aliberti et al. Future Oncol 2017


非靶栓塞可以导致

Chest & shoulder discomfort : 13% 
Nausea & vomiting : 6% 
Neurological symptoms : 4%
Woo et al. Radiology 2013


Imcomplete devascularisation

  • Uterine fibroid embolization (UFE)
            – Less fibroid devascularisation (MRI) = worse clinical  outcome
