  • a novel guidewire integrated Embolic Protection Filter device with a handy folding system in vitro and in vivo performance assessment

    Abstract:

    Objectives We developed a novel guidewire-integrated Filter device with a handy-folding system (IFD: Inoue Filter device). In vitro and in vivo studies were conducted to evaluate the feasibilityof the IFD. Background Although distal atheromatous and thrombotic embolizations remain unresolved critical issues during catheter interventions, distal Protection devices are infrequently used partly because of reduced lower maneuverability. Methods In the in vitro experiment, we created an experimental circulation model composed of silicone latex tubes, a reservoir, and a roller pump. After the Filter device was deployed in the tube, polystyrene fluorescent microspheres were injected and the capture rate was calculated. Ten trials were performed using the IFD and Spider FX. In the in vivo study, five independent operators deployed, and they retrieved the IFD in swine common iliac and internal carotid arteries. The procedural success rate as well as the delivery and retrieval time was evaluated. Results In the in vitro study, the mean capture rate was 94% and 35% in the IFD and Spider groups, respectively. In the in vivo study, all procedures were successful, with no complications. The mean delivery time was 281 ± 87 s and 194 ± 67 s and the mean retrieval time was 24 ± 9 and 13 ±1 s in the left internal carotid and the left common iliac arteries, respectively. Conclusion Although further studies and improvements are required, the study results indicate that the IFD is feasible.

  • A novel method to deliver the Filtrap coronary Embolic Protection Filter using a manual thrombectomy catheter: in vitro and in vivo comparison with the conventional method.

    Abstract:

    BACKGROUND: Although several types of distal Embolic Protection devices have been developed, they are usually difficult to use because of their stiff and bulky characteristics. We present a novel method to deliver the coronary Embolic Protection Filter via a manual thrombectomy catheter. METHODS: We modified the Filtrap Embolic Protection Filter (Nipro Corporation) to pass through the aspiration thrombectomy catheter. Three interventional cardiologists performed the Filtrap delivery with in vivo and in vitro coronary arteries using two different methods. The in vitro experiments were performed using a Circuit Cardiac Catheterization Simulator (Just Medical Corporation) with and without coronary artery stenosis. The in vivo experiment was performed using a normal pig coronary artery. The times required for Filtrap delivery in the two different methods were compared. The target lesions were the main and side branch of the left anterior descending, left circumflex, and right coronary arteries. RESULTS: The average Filtrap delivery time when using the thrombectomy catheter was significantly shorter compared to the time using the conventional method (in vitro experiment without coronary stenosis, 39 ± 14 seconds vs 30 ± 6 seconds and P=.019; in vitro experiment with multiple coronary stenosis, 69 ± 55 seconds vs 32 ± 11 seconds and P=.012; in vivo experiment, 169 ± 166 seconds vs 51 ± 12 seconds; P=.019). CONCLUSION: The study results indicate that delivery of the coronary Embolic Protection Filter via a manual thrombectomy catheter may simplify the procedure and decrease the procedure time.
