Abstract: A leaflet restraint (20) includes a non-blood-occlusive net (30), which is configured to at least partially cover an atrial surface (32) of a single native cardiac leaflet (34) of a native atrioventricular valve (36) of a heart (38). Two or more tissue-penetrating annulus anchors (40) are fixed to an annular side (42) of the net (30), and are configured to be anchored to an annulus (44) of the native atrioventricular valve (36) along or within 1 cm of a portion of the annulus (44) to which the single native cardiac leaflet (34) attaches. A ventricular anchor (50) is configured to be anchored to a ventricle (54) of the heart (58) so as to anchor a ventricular end (52) of the net (30) to the ventricle (54). The leaflet restraint (20) is configured, when anchored in place at least partially covering the atrial surface (32) of the single native cardiac leaflet (34), to limit prolapse of the single native cardiac leaflet (34) into an atrium (56) of the heart (38). Other embodiments are also described.

Abstract: A split-frame cardiac valve (20) is configured to assume a radially compressed configuration for transcatheter delivery and a radially expanded configuration for anchoring to a native cardiac valve annulus. The split-frame cardiac valve (20) includes circumferential frame segments (22) including respective stents (24) and prosthetic leaflets (30). When the split-frame cardiac valve (20) is in the radially expanded configuration: (a) each of the stents (24) surrounds less than 360 degrees of a central longitudinal axis (26) of the split-frame cardiac valve (20), (b) the circumferential frame segments (22) are slidingly coupled to one another so as to be axially slidable with respect to one another in and out of axial alignment with one another, and (c) when the circumferential frame segments (22) are axially aligned with one another, the stents (24) collectively define a tubular stent (32) that entirely surrounds the central longitudinal axis (26).

Abstract: Auxiliary components for medical devices, and more specifically, sensing constructs that may be added to a medical device such as an implantable medical device to provide the medical device with sensing functionality. The auxiliary component is not a part of the medical device, but rather is associated with an existing medical device in a secure manner, and provides information about the medical device and/or the environment around the medical device when the device is implanted in a patient, and then transmits that information to a location outside of the patient for evaluation. Delivery systems for delivering the auxiliary components.

Abstract: The present invention describes systems and methods for treating a hole in the septum, such as a patent foramen ovale or an atrial septal defect, with a closure implant designed to fluidly seal the hole to prevent blood from flowing between the right atrium to the left atrium. The closure implant includes two structures positioned on opposite sides of the hole in septum configured to close and seal the hole. The first structure is an expandable petal anchor having multiple petal groups with multiple petals of different sizes and/or shapes made of shape memory wire configured to be positioned on a distal side of the hole in the septum wall, and the second structure is a braided disk made of shape memory mesh positioned the proximal side of the hole in the septum wall, opposite the petal anchor. The braided disk is sized to cover the hole once it is expanded. The petal anchor is designed to pull and compress the braided disk against the septum wall to cover and fluidly seal the hole.
