Abstract: The invention provides systems, devices, and methods for the delivery, deployment, and positioning of magnetic compression devices at a desired site so as to improve the accuracy of anastomoses creation between tissues, organs, or the like.

Abstract: Aspects of the present disclosure relate to machine learning techniques for identifying collections of items, such as furniture items, that are visually complementary. These techniques can rely on computer vision and item imagery. For example, a first portion of a machine learning system can be trained to extract aesthetic item qualities or attributes from pixel values of images of the items. A second portion of the machine learning system can learn correlations between these extracted aesthetic qualities and the level of visual coordination between items. Thus, the disclosed techniques use computer vision machine learning to programmatically determine whether items visually coordinate with one another based on pixel values of images of those items.

Abstract: Disclosed is a system for configuring a terminal by intercepting requests, such as Input/Output (IO) requests or registry requests, evaluating rules based on the intercepted requests during runtime, and performing actions based on the rule evaluations, such as passing the request through, redirecting the request, modifying the request, hiding resources, or performing other actions. The system can be implemented in one or more of the terminal's file system filter drivers and registry filter drivers.

Abstract: A method of treating cardiovascular disease in a medical patient is provided. The method includes the steps of generating a sensor signal indicative of a fluid pressure within the left atrium of the patient's heart, and delivering an electrical stimulus to a location in the heart. The electrical stimulus is delivered based at least in part on the sensor signal. The method also includes the steps of generating a processor output indicative of a treatment to a signaling device. The processor output is based at least in part on the sensor signal. At least two treatment signals are provided to the medical patient. The treatment signals are distinguishable from one another by the patient, and are indicative of a therapeutic treatment. The treatment signals are based at least in part on the processor output.

Abstract: Systems and methods for penetrating a tissue membrane to gain access to a target site are disclosed. In some examples, systems and methods for accessing the left atrium from the right atrium of a patient's heart are carried out by puncturing the intra-atrial septal wall. One embodiment provides a system for transseptal cardiac access that includes a stabilizer sheath having a side port, a shaped guiding catheter configured to exit the side port and a tissue penetration member disposed within and extendable from the distal end of the guide catheter. The tissue penetration member may be configured to penetrate tissue upon rotation and may be coupled to a distal portion of a torqueable shaft. In some embodiments, the stabilizer sheath and shaped guiding catheter may be moved relative to the patient's body structure and relative to each other so that a desired approach angle may be obtained for the tissue penetration member with respect to the target tissue.
