Occlusive Micro Balloon Catheter

Product Overview

Microballoon Interventions a Technical Revolution in Transarterial Embolization

Terumo Interventional Oncology Division presents Occlusafe, an occlusive micro-balloon.

Through Pressure Gradient Effect, Occlusafe as micro-balloon catheter, offers the ability to redistribute blood flow and access the microcirculation, leading to an increased accumulation of therapeutics into the target lesion with minimal off-target embolization. This may be associated with improved clinical outcomes in challenging lesions3

Features and Benefits

Large Lesions Challenges:

Large lesions partially respond to current TACE treatment due to a poor uptake of embolic. Multiple or combined treatments are required to reach a complete response.

Flow Distribution

Through Pressure Gradient Effect, Balloon Occlusion with Occlusafe offers the ability to redistribute blood flow and access the microvascular circulation, leading to an increased accumulation of therapeutics into the target lesion with minimal off-target embolization.

Access to Microvascular Circulation

Balloon Occlusion with Occlusafe allows a better visualization for improved diagnosis and higher uptake of embolic into the target lesion. 1

Excellence in Navigability

Terumo excellence in lesion access technology guarantees for a superb precision and accuracy in navigation through complex vessel anatomies.

Expected Benefits from Micro Balloon Embolization (MBE)

・Greater tumor or radiological response3
・Improved clinical outcome4-6
・Better diagnosis thanks to more visibility1
・Full protection against reflux7

Standard balloon inflation for complete occlusion

Inflate balloon 1.1 or 1.2 times bigger size to the vessel
diameter. Maximal diameter is 4 mm. Maximal volume is 0.10 ml.
