“…Thus, our results demonstrated a comparable FPE to other devices such as the Solitaire stent system of 25.1%. 11 Our registry demonstrated a good final reperfusion rate (eTICI 2 b/3) with 94% that is higher than most of the commonly used thrombectomy devices 7,8 or latest generation of hybrid-stent retriever such as NeVa (93%) 12 or the EmboTrap II (76%, Neuravi/ Cerenovus), 13 and higher than the results of the recent retrospective Tigertriever study. 4 However, in 20% an additional rescue device had to be used.…”

Purpose Tigertriever is a novel operator-adjustable clot retriever designed to enhance the operator's options to control the interaction of retriever and clot. The aim of this study was to assess the feasibility, safety and efficacy of the Tigertriever device system. Methods Prospective multi-center registry study at three comprehensive stroke centers in Switzerland from 2017 to 2019 of patients with acute ischemic stroke (AIS) and large vessel occlusion (LVO) using Tigertriever as a first-line device. Results 30 AIS patients (median age 72.5 years (IQR 64–79), 50% women) with a median NIHSS on admission of 11 (IQR 6-13) and a median ASPECT score of 9 (IQR 7–10) were treated with the new Tigertriever and included in this study. The first-pass effect was 24% (n = 7). A good recanalization (eTICI 2 b/2c/3) was achieved in 94% of the cases. Median mRS at 90 days was 1 (IQR 1–2). Conclusion This study demonstrated feasibility, safety and effectiveness of the Tigertriever in AIS patients with LVO with a high reperfusion rate.

“…With the addition of our multicenter study to the prior singlecenter series of 29 patients of Valente et al, 9 we bring the total number of EmboTrap II cases in the literature to 99. Combining both datasets yields the following cumulative literature rates for EmboTrap II: final reperfusion rate (80%), FPE (35%), sICH (3%), 90-day mRS #2 (54%), mean procedure time (55.6 minutes), and distal embolization (11%).…”

“…8 The EmboTrap II stent retriever is a recent iteration that incorporates a few changes, including the following: 1) a double proximal marker to allow a more precise stent placement, and 2) an increase of outer cages from 3 to 5 to potentially improve the ability of the device to capture clots during device retraction (Fig 1). 9 To date, only 1 single-center study has evaluated EmboTrap II, with a relatively small sample size. 9 In this study, we present the first prospective multicenter experience with the EmboTrap II stent retriever.…”

BACKGROUND AND PURPOSE: EmboTrap II is a novel stent retriever with a dual-layer design and distal mesh designed for acute ischemic stroke emergent large-vessel occlusions. We present the first postmarket prospective multicenter experience with the EmboTrap II stent retriever. MATERIALS AND METHODS:A prospective registry of patients treated with EmboTrap II at 7 centers following FDA approval was maintained with baseline patient characteristics, treatment details, and clinical/radiographic follow-up.RESULTS: Seventy patients were treated with EmboTrap II (mean age, 69.9 years; 48.6% women). Intravenous thrombolysis was given in 34.3%, and emergent large-vessel occlusions were located in the ICA (n ¼ 18), M1 (n ¼ 38), M2 or M3 (n ¼ 13), and basilar artery (n ¼ 1). The 5 Â 33 mm device was used in 88% of cases. TICI $ 2b recanalization was achieved in 95.7% (82.3% in EmboTrap II-only cases), and first-pass efficacy was achieved in 35.7%. The NIHSS score improved from a preoperative average of 16.3 to 12.1 postprocedure and to 10.5 at discharge. An average of 2.5 [SD, 1.8] passes was recorded per treatment, including non-EmboTrap attempts. Definitive treatment was performed with an alternative device (aspiration or stent retriever) in 9 cases (12.9%). Some hemorrhagic conversion was noted in 22.9% of cases, of which 4.3% were symptomatic. There were no device-related complications.CONCLUSIONS: Initial postmarket results with the EmboTrap II stent retriever are favorable and comparable with those of other commercially available stent retrievers. Compared with EmboTrap II, the first-generation EmboTrap may have a higher first-pass efficacy; however, data are limited by retrospective case analysis, incomplete clinical follow-up, and small sample size, necessitating future trials.
