Clot retriever and clot retrieval device

A thrombectomy device (300) and thrombectomy equipment (1) particularly adapted for thrombectomies in intracranial blood vessels. The thrombectomy device (300) is a mesh structure defining a tubular cavity and which can transform between a retracted position and a deployed position; the mesh structure of said thrombectomy device (300) is provided with a plurality of concave stems (321) having three-dimensional contours and projecting into the tubular cavity, either end of each such concave stem (321) being fixed to said mesh structure. The thrombectomy equipment (1) comprises a guide wire, an insertion rod (100), an outer sheath (2) and an internal tube (4) movable relative to same; the guide wire passes through the internal tube (4), which is sheathed within the outer sheath (2); said internal tube (4) is movable along the guide wire. The present thrombectomy equipment (1) further comprises an insertion rod (100) connected to the thrombectomy device (300). The present thrombectomy device (300) and thrombectomy equipment (1) are able, after capture of a thrombus and during retrieval thereof, firmly to retain same, thus improving capture stability and preventing the thrombus from slipping away, thus avoiding such problems as distant blood vessels again being blocked by vascular plaque or broken fragments of thrombus. The equipment is compact and flexible.

Method, system and computer program product for determining routing of data paths in interconnect circuitry

A system, method and computer program product are provided for determining routing of data paths in interconnect circuitry for an integrated circuit. The interconnect circuitry on a first side provides a narrow interface for connection to a first device, and on a second side provides a wide interface for connection to a distributed plurality of further devices. Each data path is associated with one of the further devices and provides a connection through the interconnect circuitry between that associated further device and the first device. The method comprises the steps of defining a plurality of cells to be provided along the wide interface, each of the further devices being associated with at least one of the cells, and defining the interconnect circuitry as an array of blocks formed in rows and columns, with each cell abutting one of the columns. Further, the method includes the steps of providing a predetermined set of tiles, each tile providing a predetermined wiring layout, and for each block, applying predetermined rules to determine one of the tiles to be used to implement that block. The predetermined rules take into account the location of the block in the array and the association between the plurality of further devices and the plurality of cells, ensuring that each data path provided by the interconnect circuitry has the same propagation delay. By such an approach, a structured routing method is provided that uses predetermined tiles enabling a layout design for the interconnect circuitry to be readily produced whilst ensuring that the propagation delays are matched for each of the data paths within the interconnect circuitry.

Piezoresistive type flexible tactile sensor with double-layer fastener type micro-bosses

The invention discloses a piezoresistive type flexible tactile sensor with double-layer fastener type micro-bosses. The sensor is formed by stacking a semi-spherical protrusion, an upper-layer micro-boss array, a stretchable electrode array, a flexible pressure-sensitive array and a lower-layer micro-boss array structure which are arranged sequentially from top to bottom, wherein the flexible pressure-sensitive array is composed of a linear graphene pattern array and a flexible thin-film substrate; and the stretchable electrode array is composed of row and column strip-shaped electrodes and circular insulating barriers between the row and column strip-shaped electrodes. The stretchable electrode array is tightly attached to the flexible pressure-sensitive array; and square pins are arranged on the two sides of each linear graphene pattern, and are connected with the row and column strip-shaped electrodes respectively to form a closed loop. The double-layer fastener type micro-bosses are adopted to convert an external force effect on the tactile sensor into tensile deformation of the linear graphene patterns in the flexible pressure-sensitive array, so that the resistance change ofthe pressure-sensitive array is more obvious, and the sensitivity of the tactile sensor is improved; and meanwhile, the flexible design of the tactile sensor is realized by adopting a conductive composite material.
