Patent number: 11172934Abstract: An embolic coil conveying device and a preparation method thereof are disclosed. The embolic coil conveying device includes a pusher and an embolic coil. A distal end of the pusher and a proximal end of the embolic coil are connected to serve as a detachment section. A stretch-resistant thread is disposed in the embolic coil. The stretch-resistant thread is fixed at the proximal end of the embolic coil. A conductive wire is disposed in the pusher. The stretch-resistant thread is connected to the conductive wire. Compared with the prior art, the present invention has the advantages that the stretch-resistant thread is fixed at the proximal end of the embolic coil, so that the stretch-resistant thread is connected to the conductive wire, thereby reducing the length of the detachment section, making the detachment section more flexible, and avoiding kick-out of a microcatheter due to release of the embolic coil.Type: GrantFiled: August 9, 2018Date of Patent: November 16, 2021Assignee: MICROPORT NEUROTECH (SHANGHAI) CO., LTD.Inventors: Yuanyi Guo, Yunfei Peng, Bing Chen, Mengqi Chang, Hairui Yu, Qiaorong Jin, Yiqun Bruce Wang, Zhiyong Xie

Patent number: 11132602Abstract: An example system includes prediction workers, training workers, and a parameter server. The prediction workers store a local copy of a machine-learned model and run the mode exclusively in serving mode. The training workers store a local copy of a machine-learned model and a local snapshot and run the local copy exclusively in training mode and compare the local model or state to the snapshot after training to send delta updates to the parameter server after training. The parameter server aggregates received delta updates into a master copy of the model, sends the aggregated updates back to training workers and provides two types of updates; a real-time update based on a comparison of the master model with a local snapshot, and a full update. The real-time update occurs at least an order of magnitude more frequently than the full update and includes a subset of the weights in the model.Type: GrantFiled: August 11, 2017Date of Patent: September 28, 2021Assignee: Twitter, Inc.Inventors: Zhiyong Xie, Yue Lu, Pengjun Pei, Gary Lam, Shuanghong Yang, Yong Wang, Ziqi Huang, Xiaojiang Guo, Van Lam, Lanbo Zhang, Bingjun Sun, Sridhar Iyer, Sandeep Pandey, Qi Li, Dong Wang
