Abstract: A device, system and method for creating transmural lesions between the coronary sinus and left atrium. The device includes an elongate body that is deflectable in two locations to create a transverse portion that is substantially orthogonal to the longitudinal axis of the elongate body and a distal tip portion that defines a longitudinal axis that is parallel to the longitudinal axis of the elongate body. The device may also include two electrodes, an occlusion balloon, a hemisphere marker, and a magnet in the distal portion. In use, one device may be positioned in the coronary sinus and another device may be placed in the left atrium proximate the mitral valve, the magnets being attracted to each other and magnetically coupling the two devices against tissue, through which a transmural lesion may be created when energy is delivered from at least one of the two electrodes of each 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 method of deploying an implantable stented device in an anatomical location of a patient, including the steps of providing a delivery system with first and second stent engagement structures at its distal end, attaching a first structural element of the stented device to the first stent engagement structure and attaching a second structural element of the stented device to the second silent engagement structure, advancing the stented device to an implantation site, and sequentially disengaging the first structural element of the stented device from the first stent engagement structure of the delivery system and then disengaging the second structural element of the stented device from the second stent engagement structure.

Abstract: An isolated heart or heart-lung preparation in which essentially normal pumping activity of all four chambers of the heart is preserved, allowing for the use of the preparation in conjunction with investigations of electrode leads, catheters, ablation methods, cardiac implants and other medical devices intended to be used in or on a beating heart. The system can be designed to be used within a Magnetic Resonance Imaging (MRI) unit or a X-ray computed tomography (CT) scanner. The preparation may also be employed to investigate heart and lung functions, in the presence or absence of such medical devices. In order to allow comparative imaging visualizations of either or simultaneously the heart and/or lung structures and devices located within the chambers of the heart or vessels or bronchi within the lungs, a clear perfusate such as a modified Krebs buffer solution with oxygenation is circulated through all four chambers of the heart and thus the coronary and/or pulmonary vasculatures. A ventilator with intubation tube can be used to inflate/deflate the lungs and/or provide oxygen to the isolated organs. The preparation and recordings of the preparation may be used in conjunction with the design, development and evaluation of devices for use in or on the heart and/or lungs, as well as for use as an investigational and teaching aid to assist physicians and students in understanding the operation of the cardiopulmonary system.

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: Selective sensing implantable medical leads include pulsing and sensing portions and pulsing and not sensing portion. Leads and electrodes may be used in defibrillation and as integrated bipolar defibrillation electrodes. An entire electrode can pass charge while a valve metal or valve metal oxide portion of the electrode prevents the entire electrode from sensing, effectively rejecting unwanted signals. Differential conduction pathways, due to the valve metal and/or oxides thereof, cause the portions of the electrodes to conduct differently when used anodically and cathodically. Complex intracardiac electrical gradient can be formed along with a number of virtual electrodes within the tissue. Reentrant loops can thereby be pinned following defibrillation shock.

Abstract translation: 选择性感测可植入医疗引线包括脉冲和感测部分以及脉冲和不感测部分。 引线和电极可用于除颤和作为集成的双极除颤电极。 整个电极可以通过电荷，同时电极的阀金属或阀金属氧化物部分防止整个电极感测，有效地排除不需要的信号。 由于阀门金属和/或其氧化物导致的差动传导路径导致当阳极和阴极使用时，电极的部分不同地传导。 可以与组织内的多个虚拟电极一起形成复杂的心内电梯度。 因此，除颤休克后可以固定可重入环。
