    Abstract: An endovascular graft including a stent graft and a surgical graft is provided. The stent graft can include an elongated body having a collapsed and expanded configuration and include a frame structure covered by a compression sleeve that retains the elongated body in the collapsed configuration until deployment of the stent graft. The endovascular graft can include a first cuff member sized and dimensioned to extend into a lumen of an aortic arch branch vessel when the endovascular graft is implanted in a subject. The frame structure can include a backstop sized and dimensioned to extend into the first cuff member when the endovascular graft is implanted in the subject. The surgical graft can be partially attached to the stent graft at a proximal end portion thereof.

    Abstract: A modular dilation device (100) is provided for inserting multiple dilators into a target patient tissue site. The modular dilation device includes a first dilator (104) and a second dilator (530). The first dilator has a first dilator distal end (108) and a first dilator inner lumen (114). The first dilator has a first dilator side wall opening (118). The first dilator distal end has a first dilator open tip (116). The first dilator has a first dilator open slit (120). The first dilator open slit extends between the first dilator side wall opening and the first dilator open tip. The second dilator has a second dilator distal end and a second dilator inner lumen. The second dilator distal end has a second dilator open tip. When the second dilator is joined to the first dilator, the second dilator open tip is adjacent to the first dilator side wall opening.

    Abstract: A system to implement a deep learning network model is disclosed. The system includes machine-readable instructions and data that include a biomedical information library comprising information that includes a plurality of drugs, a plurality of biological targets, a plurality of diseases, and a plurality of adverse effects, a biomedical network system comprising a plurality of networks covering chemical, genomic, phenotypic, and cellular profiles, a score prioritizer to determine new targets for the plurality of drugs based on a concatenation of a low-dimensional vector representation for each drug vertex and each biological target vertex, and a model generator configured to generate a deep learning network model that defines a plurality of relationships between the drugs, the biological targets, and the adverse effects. The plurality of relationships defined by the deep learning network model predict drug target identification and drug repurposing.

    Abstract: An apparatus for replacing a diseased cardiac valve is movable from a radially collapsed configuration to a radially expanded configuration. The apparatus comprises an expandable support member and a prosthetic valve secured therein. The main body portion extends between first and second end portions and includes an outer circumferential surface, a circumferential axis extending about the circumferential surface, and a plurality of wing members spaced apart from one another by an expandable region. Each of the wing members includes first and second end portions and a flexible middle portion extending between the end portions. The second end portion is integrally formed with the uyimain body portion. The first end portion is adjacent the circumferential axis and substantially flush with the outer circumferential surface in the radially collapsed configuration. The first end portion extends substantially radial to the outer circumferential surface in the radially expanded configuration.
