Abstract: Systems, apparatuses, and methods disclosed herein are provided for medical treatment, including transcatheter medical treatments and/or for treatment of dilated hearts (e.g., dilated left ventricle) or functional mitral valve regurgitation within a human heart. The systems, apparatuses, and methods disclosed herein may include applying one or more heart splints to the patient's heart to apply pressure to the heart to reshape the heart. Anchors disclosed herein may be utilized in plugs for treating openings in a septum between two chambers of a heart, e.g., ventricular septal defects (VSD), atrial septal defects (ASD), and patent foramen ovale (PFO). In addition, the anchors disclosed herein may be utilized to reshape an annulus of a patient's heart valve, including a tricuspid valve of a patient's heart. The anchors disclosed herein may also be utilized to reposition a heart valve leaflet to reduce heart valve leaflet prolapse.

Abstract: An introducer device includes a proximal hub including a first port and a second port, first and second fluid valves associated with the first port and the second port, respectively, a first elongate lumen projecting distally from the proximal hub, the first elongate lumen being in fluid communication with the first port, and a second elongate lumen projecting distally from the proximal hub, the second elongate lumen being in fluid communication with the second port and fluidly isolated from the first elongate lumen.

Abstract: A prosthetic heart valve having an expandable stent modified to reduce the impact on the adjacent conduction system of the heart. A plurality of flexible leaflets arranged to close together along a flow axis through the valve prevent blood flow in one direction, and a support frame surrounds and supports the leaflets. The stent is defined by a plurality of connected struts arranged around a circumference. A pattern of the struts is consistent around the circumference except in a modified region on one side so that when converted to the expanded configuration the stent on the one side expands radially outward a smaller distance and/or has larger cells defined between the struts than around a remainder of the circumference. The stent may be connected to a non-collapsible valve member or the entire valve may be expandable. The valve may be for implant at the aortic annulus and the modified region may be centered at a commissure post of the support frame.

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: A suture system can comprise a first and a second curved double arm needle, and a needle docking device configured to maintain the first and the second curved double arm needles in alignment with and parallel to one another and at predetermined orientations relative to the needle docking device. The system can include a needle manipulating instrument having a distal portion configured to engage the first and the second curved double arm needles while the first and second curved double arm needles are in the needle docking device, and to maintain the needles in predetermined orientations.
