    Abstract: An implantable medical device is adapted to be implanted at an implantation site such as a native cardiac valve annulus. The implantable medical device includes an expandable frame that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, one or more valve cusps secured relative to the expandable frame, an inner skirt surrounding a portion of the expandable frame, and an outer skirt surrounding a portion of the expandable frame, the outer skirt attached to the expandable frame via one or more sutures that axially secure the outer skirt relative to the expandable frame yet allow the outer skirt to move radially relative to the expandable frame. The outer skirt may move radially outwards in response to fluid pressure, thereby improving fluid sealing relative to the native cardiac valve annulus.

    Abstract: A device for compressing a stent may include a housing extending along a central longitudinal axis, a first threaded member and a second threaded member, a first iris and a second iris, and a compressor element disposed between the second iris and the second threaded member. The first iris includes a first ring extending transverse to the axis and a first plurality of arms extending from the first ring parallel to the axis. The first plurality of arms defines a first central opening and rotation of the first threaded member changes a size of the first central opening. The second iris includes a second ring extending transverse to the axis and a second plurality of arms extending from the second ring parallel to the axis. The second plurality of arms defines a second central opening and rotation of the second threaded member changes a size of the second central opening.

    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 support structure for a heart valve implant may include an expandable metallic scaffold configured to be actuated between a delivery configuration and a deployed configuration, and a seal member formed from a polymeric material, the seal member being disposed about the expandable scaffold, wherein a first portion of the seal member immediately adjacent the expandable scaffold is directly attached to the expandable scaffold and a second portion of the seal member immediately adjacent the expandable scaffold is unattached to the expandable scaffold.
