“…A comprehensive list of past and current MT devices is given in Table 3 . Coil retriever devices and the early Penumbra aspiration system [ 88 , 89 ] were the first generation of MT devices; they failed to show long-term improvements in clinical outcomes despite satisfactory revascularization efficacy (up to 50%) [ 90 ]. Coil retrievers such as MERCI [ 91 – 94 ], Phenox [ 95 , 96 ] and Catch retrievers [ 97 – 99 ] use microcatheter to deliver a coiled wire across the targeted clot in the occluded artery [ 91 – 94 ].…”

Following the success of recent endovascular trials, endovascular therapy has emerged as an exciting addition to the arsenal of clinical management of patients with acute ischemic stroke (AIS). In this paper, we present an extensive overview of intravenous and endovascular reperfusion strategies, recent advances in AIS neurointervention, limitations of various treatment paradigms, and provide insights on imaging-guided reperfusion therapies. A roadmap for imaging guided reperfusion treatment workflow in AIS is also proposed. Both systemic thrombolysis and endovascular treatment have been incorporated into the standard of care in stroke therapy. Further research on advanced imaging-based approaches to select appropriate patients, may widen the time-window for patient selection and would contribute immensely to early thrombolytic strategies, better recanalization rates, and improved clinical outcomes.

“…The application of flow arrest proximal to the clot using a balloon guiding catheter has been used to reduce the likelihood of clot fragmentation and distal embolization 14 15. Similarly, more distal flow arrest may be achieved through the combined use of stent retrievers and suction with a distal access catheter at the clot interface (the ‘Solumbra’ technique) or suction through a distal access catheter alone may be used (the ‘ADAPT’ technique (a direct aspiration as a first pass technique) 16–18.…”

“…Moreover, a large amount of t-PA brings high risk of hemorrhage. Therefore, the successful treatment of ischemic stroke and heart disease crucially depends on time, short recanalization time is urgently desired after the symptom onset (Pereira et al, 2015).…”

Recently medical treatment device using a complex vibration is developed, it has been designed for the improvement of the conversion efficiency. However, few reports are available on the vibration transducers as used in small blood vessel. In this paper, the new type longitudinal-torsional complex vibration transducer was designed. The principle of vibration conversion from longitudinal vibration to longitudinal-torsional complex vibration was described in detail. In order to obtain the most effective performance, the structure parameters of the vibrator involving the mode conversion were mentioned. The important parameters to achieve the highest conversion efficiency from longitudinal vibration to torsional vibration were investigated by using the finite element method analysis models. The angled-multilayered converter was designed, and the important parameters as layers offset angle and lead angle of twist structure were discovered. The most effective parameters were obtained for the offset angle was 10 degree and the lead angle was 56-59 degree. It was confirmed that the vibration conversion efficiency was improved by making a hole for the suction into the device.
