Abstract P33: Blind Exchange With the Mini-Pinning Technique Using Tron Fx Retriever for M2 Occlusion Thrombectomy

Introduction: Technical improvement to enhance M2 occlusion thrombectomy is desirable. Tron FX® is the only stent-retriever that can be deployed through 0.0165-inch microcatheters. Here we report outcomes of blind exchange with mini-pinning (BEMP) technique using Tron stent-retrievers. Methods: Consecutive stroke patients with M2 occlusion treated with 2 x15 mm or 4 x 20 mm Tron stent-retrievers using the BEMP technique were included. The technique involves the deployment of a Tron stent-retriever through a 0.0165-inch microcatheter followed by microcatheter removal and blind navigation of a 3/4MAX aspiration catheter over the bare Tron delivery wire until the aspiration catheter reaches the clot,. Tron stent-retriever was inserted into aspiration catheter like corkscrew, and subsequently pulled as a unit. A first pass effect (FPE), modified FPE (mFPE) and modified Rankin Scale (mRS) score at 90 days were assessed as outcomes. Results: Fifteen M2 vessels were treated in 13 patients (5 women, median 81 years of age, and median National Institutes of Health Stroke Scale score 18 [11–25]). BEMP technique was successful in all cases. Whether to use 3MAX or 4MAX was determined according to the target vessel size while proceeding with the procedure (3MAX, n=8; 4MAX, n=5). Final mTICI 2b–3 was achieved in 92% (12/13). FPE and mFPE rates were 50% and 64%, respectively. Six patients (46%) were achieved in mRS score 0–2 at 3 months. Conclusions: Tron stent-retriever was successfully and safely used in the BEMP technique for M2 occlusion

Robot Assisted Routing and Navigation System for Visually Impaired People

This paper deals with the work on creating a robot assisted navigation system for the visually impaired people. The ability to see is an important gift that helps human beings to live their everyday lives, but not all people are blessed with this ability. The normal blind navigation devices deals with on-body devices that the user must carry, but this paper is talking about is a small rover that can be held by the user using a hanlde. The device will contain a raspberry pi module for taking data from a camera on-board to see the environment and make object and obstacle detection. The 4-WD rover will be controlled by an Arduino device which will be connected to the mobile of the user via a Bluetooth module. The user just has to say the name of the location he needs to go to by opening an application, the rest of the routing and transport will be done by the raspberry pi and Arduino.
