    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: A delivery system for an implantable stented device having a handle with a plurality of actuation members, each actuation member connected to one or more stent attachment elements, a sheath having a proximal end attached to the handle, and a plurality of tubes extending within the sheath. The stent attachment elements extend from distal ends of the tubes. A first actuation member is configured to move a first stent attachment element proximally toward the handle and a second actuation member is configured to move a second stent attachment element proximally toward the handle, sequentially releasing specific portions of the stented device by causing distal ends of the stent attachment elements to contact an exterior of the distal ends of the tubes, thereby disengaging the first and second stent attachment elements from the stented device.

    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.
