  • Publication number: 20240098991
    Abstract: In one example, a system comprises an array comprising selected memory cells; an input block configured to apply, to each selected memory cell, a series of input signals to a terminal of the selected memory cell in response to a series of input bits; and an output block for generating an output of the selected memory cells, the output block comprising an analog-to-digital converter to convert current from the selected memory cells into a digital value, a shifter, an adder, and a register; wherein the shifter, adder, and register are configured to receive a series of digital values in response to the series of input bits, shift each digital value in the series of digital values based on a bit location of an input bit within the series of input bits, and add results of the shift operations to generate an output indicating values stored in the selected memory cells.

  • Publication number: 20230270460
    Abstract: A medical device for removal of an occlusion from a vessel in a patient’s body. The retrieval device having a retriever sub-system and an aspiration sub-system. The retriever sub-system having a delivery catheter and an elongated delivery member that includes proximal and distal expandable elements, the proximal element being removably engaged to the elongated delivery member and the distal element being fixed to the elongated delivery member. The proximal element adapted to move axially along the elongated delivery member in a distal direction toward the distal element when the proximal element is released from the elongated delivery member, whereby, when the proximal element is disposed on a distal side of the vessel occlusion and the distal element is disposed on a proximal side of the occlusion, the proximal and distal elements surround, isolate and contain the occlusion between the proximal and distal elements at the vessel occlusion site.

  • Publication number: 20220387057
    Abstract: A valve system for a catheter, such as an aspiration catheter, is disclosed and includes a valve having a proximal end and a distal end. The distal end of the valve is coupled to the catheter. The valve has a flexible lumen in a first state that is constricted or twisted. The valve system is housed within a hub, where actuation of a button on the hub causes the proximal and distal ends of the valve to rotate relative to each other to put the lumen in a second state that is unconstricted or untwisted state.

  • Publication number: 20220387058
    Abstract: The present specification is directed towards catheter devices having expandable and collapsible lumens. Air or fluid is pumped into the catheter wall to cause it to expand. Alternatively, wires are embedded within the wall and a direction of flow of electrical current through the wires is modulated to enable the catheter device to be in the collapsed or expanded state. For example, a first wire is embedded within the wall and is helically wound along a length of the catheter device. A second wire is provided that can be removably positioned within the lumen. The direction of flow of electric current through the first and second wires is modulated to enable the catheter device to be in the collapsed or expanded state.
