Abstract: Methods and systems for managing distribution of inference models throughout a distributed system are disclosed. To manage distribution of inference models, a system may include a data aggregator and one or more data collectors. The data aggregator may obtain a threshold, the threshold indicating an acceptable inference error rate for an inference model. The data aggregator may obtain an inference model based on the threshold by training an inference model, performing a lookup in an inference model lookup table, or via other methods. The data aggregator may optimize the inference model to determine the minimum quantity of computing resources consumed by an inference model in order to generate inferences accurate within the threshold. In order to do so, the data aggregator may simulate the operation of more computationally-costly inference models and less computationally-costly inference models.

Abstract: A device, a thrombectomy apparatus and a method for extraction of thrombus from a blood vessel are disclosed. The device comprises a segment changing its shape from a retracted position in a compressed state to an extended and expanded position. The segment is formed by a mesh of at least two sets of helicoidal filaments turning respectively in opposite directions and being intertwined. The mesh comprises two distinct tubular sections. The mesh of the first section has helicoidal filaments with a braiding angle providing radial forces higher than in the second section, thus the first section becomes appositioned against the inner wall of the blood vessel. The second section comprises two sub-sections. The first sub-section has a conical shape and comprises a braiding angle changing at its proximal and distal ends to provide radial strength to maintain the conical shape and to stop a proximal blood flow during the removal of the thrombus.

It further adapts later queries to use the optimized persistent views.
