Abstract: A method of tethering can comprise providing a tether deployment device. The tether deployment device can comprise an elongate shaft comprising a lumen extending from a proximal end to a side opening, an atraumatic distal effector coupled to a distal end of the elongate shaft, and a tether deployment assembly at least partially received within the lumen. The method can include advancing the distal portion of the elongate shaft into a heart chamber, positioning a distally oriented surface of the atraumatic distal effector against a first tissue area, and advancing a distal portion of the tether deployment assembly through the side opening of the shaft. A portion of at least one tether can be deployed to the target tissue area using the tether deployment assembly while the distally oriented surface of the atraumatic distal effector is against the first tissue area.

Abstract: Described herein are methods and apparatus for implanting grafts to leaflets for cardiac procedures that are performed minimally-invasively while the heart is beating. The graft elongates, reinforces, and patches the leaflet. In certain disclosed examples, the graft is secured to the atrium or ventricle side of the leaflet with an artificial cord implanted on an edge of the graft to improve coaptation. In some disclosed examples, the graft is secured to both leaflets to enable an edge-to-edge procedure similar to the Alfieri technique. Some examples of the disclosed methods including introducing the graft into the ventricle and guiding it into place using artificial cords previously implanted in the leaflet.

Abstract: An annuloplasty ring for repair of mitral valves whose shape can be altered directly or remotely to perform post-implant size and/or shape adjustments. One version of the annuloplasty ring has a size-adjustable remodeling inner core within an outer suture-permeable interface for attaching the ring to an annulus. The inner core has a size-adjustable segment formed by short spaced-apart tubular sections that can move toward and way from one another such as on rails. Alternatively, short sections separated by compressible connectors may be used. One or more tethers may be attached to one side of the size-adjustable segment and pulled from the other side to constrict the segment. Multiple tethers may be connect at different locations around the ring to provide some control over where the ring constricts. An adjustment handle with a flexible shaft may be operated from outside the body to adjust the ring post-implant.

Abstract: Systems, apparatuses, and methods disclosed herein may be directed to clips for medical implementation, including clips for a portion of a heart. The clips may be configured to close the portion of the heart, to reduce blood flow therethrough as well as passage of clots or other undesired materials. In examples, the clips may be configured to close the left atrial appendage (LAA). The closure of the LAA may reduce the possibility of stroke or other maladies stemming from fluid flow with the LAA. In examples, the clips may be positioned exterior of the LAA, to extend over an outer surface of the LAA for closure.

Abstract: Septal defect repair involves advancing an elongate shaft into an atrium of a heart of a patient through an outer atrial wall of the heart, contacting an atrial septum of the heart with a distal end of the elongate shaft, deploying a plurality of tissue anchors from the elongate shaft in tissue of the atrial septum, and cinching suture tails associated with the plurality of tissue anchors to at least partially close a defect in the atrial septum.
