Microcatheter compatibility for  particle delivery

Microcatheters’ characteristics

• Material:

• Introduction of multiple tip shapes:

Catheter to microsphere  compatibility  [kəmˌpætəˈbɪləti] 

Recommendation

• Rely on the inner diameter for particle compatibility  for size and deliverability.
• Discrepancies [disˈkrepənsiz] between the size of the distal  catheter in French(OD) and the inner diameter  across the different companies.
• 2.8F distal Boston inner diameter 0.027
• 2.8F distal Merit inner diameter 0.024
• 2.9F distal Merit inner diameter 0.027

√ Once the choice of the microcatheter is established:

• Based on the target organ (vessel)
• Particles

• Optimal dilution: contrast/saline ratio
• Optimal suspension  [səˈspenʃn]
