  • Patent number: 12133799
    Abstract: Devices including a capsule having an interior and a clamp assembly including a plurality of clamps. Each clamp includes a first arm having a first free end and a second arm having a second free end. The device includes a clamp assembly including a compacted state in which the plurality of clamps are compressed within the capsule and a deployed state in which at least the free ends of the plurality of clamps are positioned outside of the interior of the capsule. The first free end is closer to the second free end in the compacted state as compared to the deployed state. The device can further include a push rod releasably secured to the clamp assembly and a delivery rod releasably secured to the capsule. Methods of using the devices are also disclosed.

  • Patent number: 12086698
    Abstract: A field extraction system that does not require field-level annotations for training is provided. Specifically, the training process is bootstrapped by mining pseudo-labels from unlabeled forms using simple rules. Then, a transformer-based structure is used to model interactions between text tokens in the input form and predict a field tag for each token accordingly. The pseudo-labels are used to supervise the transformer training. As the pseudo-labels are noisy, a refinement module that contains a sequence of branches is used to refine the pseudo-labels. Each of the refinement branches conducts field tagging and generates refined labels. At each stage, a branch is optimized by the labels ensembled from all previous branches to reduce label noise.

  • Patent number: 12070213
    Abstract: Surgical stapling devices have a surgical buttress attached to an anvil jaw member, a cartridge jaw member, or both. In use, the surgical buttress reinforces a staple line formed upon application of staples from the surgical stapling device and minimizes leaks which may exude from the staple line and/or tissue being stapled by the surgical stapling device.

  • Publication number: 20200022807
    Abstract: A method of forming an electrospun prosthetic valve includes utilizing a rotatable and angularly adjustable prosthetic valve mold. The prosthetic valve mold is set to a first angle. The prosthetic valve mold is rotated at a first rotational velocity and a first layer of electrospun fibers is deposited on the prosthetic valve mold. The prosthetic valve mold is stopped and a frame is positioned over the first layer. The prosthetic valve mold is set to a second angle. The prosthetic valve mold is rotated at a second velocity and a second layer of electrospun fibers is deposited on an outer surface of the first layer and an outer surface of the frame.

  • Patent number: 9034349
    Abstract: In the present invention, the applicants describe methods and compositions of treating damaged cardiovascular elements and cardiovascular conditions including hypotension, atherosclerotic lesions, vulnerable plaque, and acute myocardial infarct. The applicants demonstrate the ability of a biomembrane sealing agent to accumulate on the walls of damaged blood vessels and help improving mean arterial pressure following tissue injury. The applicants describe the use of formulations comprising at least one biomembrane sealing agent and one bioactive agent for prophylactic treatment such as they could be administered concurrently to an invasive therapeutic intervention or after the insult (i.e. post-injury or post-surgery). Alternatively, these methods and compositions could be used to reduce the severity of cardiovascular diseases after onset.
