Abstract: A compressible and expandable stent assembly for implantation in a body lumen such as a mitral valve, the stent assembly including at least one stent barrel that is shaped and sized so that it allows for normal operation of adjacent heart structures. One or more stent barrels can be included in the stent assembly, where one or more of the stent barrels can include a cylinder with tapered edge.

Abstract: Systems and methods for modifying a heart valve annulus in a minimally invasive surgical procedure. A helical anchor is provided, having a memory set to a coiled shape or state. The helical anchor is further configured to self-revert from a substantially straight state to the coiled state. The helical anchor is loaded within a needle that constrains the helical anchor to the substantially straight state. The needle is delivered to the valve annulus and inserted into tissue of the annulus. The helical anchor is then deployed from the needle (e.g., the needle is retracted from over the helical anchor). Once deployed, the helical anchor self-transitions toward the coiled shape, cinching engaged tissue of the valve annulus.

Related devices, kits and sizer devices.

Abstract: Implantable medical device including a pulsed-voltage generator and one or more implantable electrical leads. In one example, the implantable medical device supports the defibrillator and ablation modalities characterized by different respective sets of waveform parameters, such as the pulse amplitude and width. In some examples, the implantable medical device also supports a pacing modality. The electrodes used for the different modalities are variously selected from a plurality of electrodes located in distal portions of the implantable electrical leads and on the exterior surface of the implantable device box. An electronic controller of the implantable medical device is wirelessly programmable to appropriately control, e.g., in a patient-specific manner, operations of the pulsed-voltage generator and transitions between different modalities. Various examples of the disclosed implantable medical device can beneficially be used to provide to a cardiac patient a greater variety of treatment options without having to replace the implantable medical device.

Abstract: Methods and systems for monitoring and modifying pulsed field ablation (PFA) energy delivery to prevent patient safety risks and/or delivery device failure. In particular, some embodiments provide methods and systems for detecting and preventing arcs and arc-induced plasma, and their causal events, during delivery of pulsed field ablation energy, as well as methods and systems for identifying conditions leading to potential delivery device failure and correcting charge imbalance or asymmetry.

Abstract: A stented valve having at least one leaflet made of pericardium or other material having a relatively thin profile at the annulus. The leaflets are attached via chords to a stent frame, where the chords are positioned to mimic the native valve anatomy and functionality. In particular, the valves of one exemplary embodiment of the invention are sized to replace a mitral valve and therefore the chords are arranged to prevent prolapse of the leaflets into the atrium. The stented valve has a relatively short height at its annulus due to the positioning of the chords. In addition, the stented valve is capable of being crimped to a small enough size that it can be delivered to the implantation site via transcatheter delivery systems and methods.
