  • Publication number: 20220370097
    Abstract: A system for reshaping a valve annulus includes an elongate template having a length along a longitudinal axis and at least one concavity in a generally lateral direction along said length. The pre-shaped template is positioned against at least a region of an inner peripheral wall of the valve annulus, and at least one anchor on the template is advanced into a lateral wall of the valve annulus to reposition at least one segment of the region of the inner peripheral wall of the valve annulus into said concavity. In this way, a peripheral length of the valve annulus can be foreshortened and/or reshaped to improve coaptation of the valve leaflets and/or to eliminate or decrease regurgitation of a valve.

  • Publication number: 20220317914
    Abstract: Storage devices include a memory array comprised of a plurality of memory devices. These memory devices are programmed to store data and erased when data is invalidated. Traditional storage devices waited to erase memory devices until new data was ready to write to them in order to avoid baking in the erase state. However, the act of erasing adds time to the overall program cycle and is getting larger as storage device capacity and complexity increases. Because of newer configurations, the threat of baking in erase states is decreased, allowing memory devices within a memory array to be pre-erased prior to writing. This reduces write times and be dynamically implemented in response to one or more changing conditions. Pre-erasing can be accomplished by utilizing a pre-erase list that can indicate pre-erased memory devices and provide them in response to a write command prior to the use of non-erased memory devices.

  • Patent number: 11462279
    Abstract: Storage devices include a memory array comprised of a plurality of memory devices. These memory devices are programmed with a modified distribution across the available memory states within the devices. The modified distribution of memory states attempts to minimize the use of memory states that are susceptible to negative effects. These negative effects can include read and write disturbs as well as data retention errors. Often, these negative effects occur on memory states on the lower and upper states within the voltage threshold range of the memory device. The distribution of memory states can be modified though the use of a modified randomization seed configured to change the probabilities of programming of each page within the memory device. This modification of the randomization seed can yield desired distribution of memory device states that are configured to reduce exposure to negative effects thus prolonging the overall lifespan of the storage device.

  • Publication number: 20220301645
    Abstract: Storage devices are capable of utilizing failed bit count (FBC) reduction devices to reduce FBCs for word lines in blocks. An FBC reduction device may include a FBC count component, a threshold component, a pre-verify component, and a soft program component. The FBC count component may access the FBC for the word line, where the block has unprogrammed word lines in an unprogrammed region separated from programmed word lines of a programmed region by the word line. The threshold component may determine whether the FBC of the word line exceeds a predetermined threshold. When the FBC exceeds the threshold, the pre-verify component may perform pre-verify operations on the programmed region. The soft program component may program the word line with first data equal to second data programmed in a second block. In response to disabling pre-verify operations, the program component may program the unprogrammed word lines in the unprogrammed region.

  • Publication number: 20220206920
    Abstract: Aspects of a storage device are provided which delay thermal throttling in response to temperature increases based on different reliable temperatures for different types of cells, such as SLCs, hybrid SLCs and MLCs. Initially, a controller writes first data to a block of MLCs at a first data rate when a temperature of the block meets a first temperature threshold for MLCs. Subsequently, the controller writes second data to the block at a second data rate lower than the first data rate when the temperature of the block meets a second temperature threshold for SLCs. For hybrid SLCs, the MLCs are each configured to store a first number of bits, and the controller writes a second number of bits smaller than the first number of bits in each of one or more of the cells. Storage device performance is thus improved through delayed thermal throttling without compromising data integrity.

  • Publication number: 20220183843
    Abstract: A catheter system for delivering an anchor to a valve annulus in a heart valve includes a locating catheter and an anchor delivery catheter. The locating catheter has a distal end which can be advanced beneath the valve annulus near a target site on an upper surface of the valve annulus. The anchor delivery catheter has a distal end which can be advanced over the valve annulus to deliver an anchor along a delivery path to the target site. The distal end of the locating catheter has at least one magnetic element, and the distal end of the anchor delivery catheter has at least one magnetic element which attracts the at least one magnetic element on the locating catheter to pivotally couple the distal end of the anchor delivery catheter to the distal end of the locating catheter. In this way, the deliver catheter can be pivoted relative to the locating catheter to orient the delivery path away from the locating catheter.

  • Publication number: 20220179578
    Abstract: Storage devices may be configured to desirably reduce the time required to perform a physical secure erase operation. The storage device includes a controller that is configured to direct the storage device to receive a physical secure erase command. The storage device can then identify the one or more blocks within the memory array for secure erasure based on the received physical secure erase command. For each block identified for erasure, the storage device further evaluates the block to determine the level type of cells within the block. In response to the cell level type being single-level, a single-cell erase command is issued to perform a single-level cell erase on the block. Conversely, in response to the cell level type being a higher-dimensional cell, a modified single-cell erase command to perform a modified single-level cell erase on the block is issued.

  • Publication number: 20220125450
    Abstract: An aspiration catheter for removing clot from a blood vessel includes a catheter body having a scaffold extending distally from a distal end of the body. An aspiration lumen runs from the distal end to a proximal end of the body, and a central clot-receiving passage in the scaffold is contiguous with the aspiration lumen of the catheter body. A vacuum-resistant membrane covers the scaffold and establishes a clot aspiration path from a distal end of the scaffold to a proximal end of the aspiration lumen, in the catheter body so that applying a vacuum to the proximal end of the aspiration lumen can draw clot into the central clot-receiving passage. The scaffold may have a comical configuration, a cylindrical configuration, or a combination thereof, and at least a distal portion of the scaffold is radially expandable from a delivery configuration to an extraction configuration.

  • Publication number: 20210406107
    Abstract: A storage device may detect errors during data transfer. Upon detection of one or more data transfer errors, for example, the storage device can begin to scan pages within a plurality of memory devices for uncorrectable error correction codes. Once scanned, a range of pages within the plurality of memory devices with uncorrectable error correction codes associated with a write abort error may be determined. The stage of multi-pass programming achieved on each page within that range is then established. Once calculated, the previously aborted multi-pass programming of each page within the range of pages can continue until completion. Upon completion, normal operations may continue without discarding physical data location.
