  • Publication number: 20240000559
    Abstract: Methods and systems for cardiovascular structure reconstruction are provided. A method of reconstructing a cardiovascular structure may include imaging the cardiovascular structure, producing a three-dimensional model of the cardiovascular structure based on the imaging, and creating a three-dimensional model of a patch corresponding to the three-dimensional model of the cardiovascular structure, where the patch is configured to reconstruct the cardiovascular structure to a normal geometry. A patch for a cardiovascular structure may include at least one layer of anisotropic material including an outermost perimeter and one or more notches extending inward from the outermost perimeter, where each of the one or more notches creates a discontinuity in the outermost perimeter. In some cases, each of the one or more notches includes a first edge and a second opposing edge, and the patch further includes one or more sutures configured to secure the first edge to the second opposing edge.

  • Publication number: 20230372087
    Abstract: An engineering workflow for prospective design of heart valve leaflet grafts for surgical heart valve reconstruction is disclosed. The engineering workflow includes utilizing a quantitative description of one or more mechanical properties of one or more materials to be used for the heart valve reconstruction to prescribe a size and/or a shape of the materials to achieve a predetermined configuration of a final reconstructed heart valve in its physiological working state for a given patient.

  • Publication number: 20230211045
    Abstract: An implantable, autonomously growing medical device is disclosed. The device may have an outer, braided outer element that holds an inner core. Degradation and/or softening of the inner core permits the outer element to elongate, allowing the device to grow with surrounding tissue. The growth profile of the medical device can be controlled by altering the shape/material/cure conditions of the inner core, as well as the geometry of the out element.

  • Publication number: 20230039350
    Abstract: Method and devices for viewing one or more valve leaflets via a viewer. In some embodiments the viewer includes a body having a first end and a second end opposite the first end, the first end being closed and having a transparent viewing window, the second end arranged to be attached to an aorta or a pulmonary artery, and one or more ports arranged to provide fluid access to an internal portion of the viewer to pressurize the one or more leaflets. A diameter of the viewing window is larger than an outer diameter of the second end. An outer diameter of the first end of the body is larger than an outer diameter of the second end. The body is a tubular body.

  • Publication number: 20210322170
    Abstract: A repair device for closing a valve of a heart includes a main stem. The mains stem has a distal end and a proximal end. The main stem comprises a papillary anchor on the proximal end. The papillary anchor of the main stem is configured to attach to a papillary muscle of the heart. The main stem further includes a first branch extending from the main stem in a first direction and configured to attach to a first leaflet of the valve of the heart. The main stem also includes a second branch extending from the main stem in a second direction different from the first direction and configured to attach to a second leaflet of the valve. The first and second branches are flexible.
