Summary
The Optimo balloon guide catheter (BGC) provided better support, while the Branchor and Flowgate BGCs demonstrated superior guiding performance in mechanical thrombus retrieval models.
Area of Science:
- Biomedical Engineering
- Medical Device Technology
- Interventional Cardiology
Background:
- Mechanical thrombus retrieval utilizes various balloon guide catheters (BGCs).
- Direct comparative data on BGC supporting and guiding performance is lacking.
- This study evaluates three BGCs: Branchor, Flowgate, and Optimo.
Purpose of the Study:
- To compare the supporting and guiding performance of Branchor, Flowgate, and Optimo BGCs.
- To provide data for selecting optimal BGCs in endovascular procedures.
Main Methods:
- Utilized a type 3 aorta artificial vascular model for testing.
- Assessed supporting performance via inner catheter insertion resistance and BGC slippage.
- Evaluated guiding performance by measuring BGC reach, insertion resistance, and inner catheter slippage.
Main Results:
- No significant difference in supporting performance across all tested BGCs.
- Optimo BGC suggested better supporting performance in initial trials.
- Branchor and Flowgate BGCs demonstrated significantly superior guiding performance compared to Optimo.
Conclusions:
- Optimo BGC exhibits superior supporting capabilities.
- Branchor and Flowgate BGCs offer enhanced guiding performance.
- BGC selection should consider a balance between supporting and guiding needs.
