Abstract: A stented valve prosthesis for implantation within a native mitral valve having a generally tubular expandable stent structure having a first end, a second end, a central body portion having one or more openings, and a longitudinal axis. A wing portion extends outwardly from the stent structure and away from the longitudinal axis of the stent structure in an expanded deployed configuration. A radius of the wing portion is greater than a radius of the central body portion in the expanded deployed configuration, and the wing portion fits within one of the openings in the central body portion of the stent structure in a crimped delivery configuration. A valve structure having a plurality of leaflets is attached to an interior of the stent structure.

Abstract: A device, system, and method for optically evaluating and treating or ablating tissue. Specifically, device, system, and method allow for the optical and/or electrical evaluation of tissue at the same location(s) at which ablation or treatment or ablation energy is delivered. This allows for a more accurate evaluation of lesion formation and tissue condition before, during, and/or after a treatment or ablation procedure. In one embodiment, a device for performing a medical procedure includes an elongate body including a proximal portion, a distal portion having a distal end, and a longitudinal axis, and a distal tip electrode at the elongate body distal end, the tip electrode being optically transparent and electrically conductive. The device may also include optical windows in the elongate body aligned with one or more transparent lateral electrodes for optically interrogating tissue and/or for delivering treatment or ablation energy to tissue.

Abstract: A medical device is configured to deliver pulsed electric field (PEF) energy to tissue and includes an elongated shaft having a proximal portion and a distal portion. A balloon is coupled to the distal portion of the elongated shaft. A plurality of electrodes is disposed on an outer surface of the balloon and configured to apply PEF energy to tissue. The balloon defines one or more irrigation channels proximate to or on the plurality of electrodes, the one or more irrigation channels being configured to irrigate at least one of the plurality of electrodes.

Abstract: A stented valve including a generally tubular stent structure that has a longitudinal axis, first and second opposite ends, a plurality of commissure support structures spaced from the first and second ends and extending generally parallel to the longitudinal axis, at least one structural wire positioned between each two adjacent commissure support structures, and at least one wing portion extending from two adjacent commissure support structures and toward one of the first and second ends of the stent structure. The stewed valve further includes a valve structure attached within the generally tubular stent structure to the commissure support structures.
