    Abstract: A replacement heart valve implant may include an expandable framework having a plurality of frame struts defining a lattice structure, each frame strut having a thickness in a radial direction from a central longitudinal axis; and a plurality of valve leaflets coupled to the expandable framework. The plurality of frame struts defines a lower crown proximate an inflow end of the lattice structure and upper crown proximate an outflow end of the lattice structure and a plurality of stabilization arches extending downstream from the outflow end of the lattice structure. The lattice structure includes a first circumferential row of x-connectors upstream of the upper crown and a second circumferential row of x-connectors downstream of the lower crown. The thickness of at least some frame struts connecting the first and second circumferential rows of x-connectors is less than the thickness of other frame struts of the plurality of frame struts.

    Abstract: Embodiments include devices, methods, and systems for positioning devices. An exemplary method comprises: moving a distal end of a tube into a body, the tube including a lumen and a shaft in the lumen, the shaft having a transducer; sending a first signal to the transducer; passing, with the transducer, in response to the first signal, a wave energy into the body; receiving, with the transducer, a reflected portion of the wave energy; generating, with the transducer, a second signal in response to the reflected portion of the wave energy; determining, with a processor, an indicia of the body in response to the second signal; and identifying, with the indicia, a targeted issue in the body; positioning the distal end of the tube at the targeted tissue in response to the indicia; and removing a portion of the targeted tissue with the distal end of the tube.

    Abstract: A balloon valvuloplasty catheter may include an elongate shaft having a guidewire lumen and a device lumen extending longitudinally therein, an expandable balloon secured to a distal portion of the elongate shaft, and an intravascular ultrasound catheter slidably disposed within the device lumen. The device lumen is in fluid communication with an interior of the expandable balloon. A method of preparing a native aortic heart valve of a patient's heart for transcatheter aortic valve replacement may include using the balloon valvuloplasty to observe via intravascular ultrasound and evaluate a position of the native leaflets relative to the left and right coronary artery ostia to determine if the native leaflets block the left coronary artery ostium and/or the right coronary artery ostium when the expandable balloon is inflated.

    Abstract: A system for transluminal delivery of cardiac repair components into a heart includes a visualization catheter having an imaging device disposed at a distal end. An anchor lumen extends through the visualization catheter to an anchor port disposed on its distal wall. An adjustment mechanism is translatably disposed within the visualization catheter and configured to adjust a height of the anchor port relative to a septum of the heart. The imaging device may be used to visualize the placement of anchors expelled from the port into a tissue target. The adjustment mechanism enables accurate placement of multiple anchors along a consistent axis within the heart by rotating the visualization catheter to align the port with different tissue targets. The anchors may be coupled to sutures and the tissue targets may include papillary muscles that are reconfigured by pulling together and securing the sutures to approximate a healthy papillary structure.

    Abstract: A guidewire system may include a guidewire having a relatively stiff proximal section and a relatively flexible distal section joined by a transition region, and a TAVI device slidably disposed on the guidewire. The guidewire may include an expandable element disposed about the transition region. The expandable element may be configured to expand from a collapsed configuration to an expanded configuration. The guidewire may include an expandable element disposed at the distal end. The distal section may be pre-configured to form more than one distal loop. A method of protecting an apex of a left ventricle during a TAVI procedure may include inserting a guidewire into the left ventricle, positioning a transition region adjacent the apex, expanding an expandable element such that the expandable element spans the apex, advancing a TAVI device distally over the guidewire to an aortic valve, and performing a TAVI procedure at the aortic valve.
