摘要： Medical devices and methods for deriving an indication of occlusion of a blood vessel from one or more physiologic sensor are disclosed. The physiological parameters contemplated for implementation in accordance with embodiments of the disclosure may include pressure, flow, force, temperature, or tension. An exemplary device comprises a catheter having an expandable chamber coupled to a distal end portion of the catheter shaft. In various embodiments, one or more physiologic sensors may be disposed on the catheter shaft and electrically coupled to control electronics that may be provided in a console for measurement of a physiologic signal. Alternatively, an external sensor may be disposed in fluid communication with a lumen of the catheter to derive a physiological parameter such as pressure via mechanical coupling of pressure distal to the expandable chamber to the fluid in the lumen. The parameters measured by the physiologic sensor(s) provide a measure of the physiological parameters in at least a first region. The physiological parameter measured in the first region is evaluated to obtain an indication of occlusion distal to the expandable chamber. In other embodiments, measurements of the physiological parameters may be performed in the first region and a second region to derive differential measurements that are evaluated to obtain an indication of occlusion.

摘要： The present invention provides a medical device having an elongate body with both a proximal end and a distal end, wherein the elongate body defines an intake lumen and an exhaust lumen. The medical device also has a first pliable element defining a cooling chamber disposed at a point along the elongate body, with the cooling chamber being in fluid communication with the intake lumen and the exhaust lumen. A second pliable element is provided which at least partially encloses the first pliable element, thereby defining a junction between the first and second pliable element. Moreover, a check valve is included which is in fluid communication with the junction between the first pliable element and second pliable element, the valve further being in fluid communication with the exhaust lumen. In addition, the medical device may include sensors or other monitoring means in fluid communication with the junction and the cooling chamber.

摘要： The present invention advantageously provides a method and system for cryogenically ablating large areas of tissue within the left atrium. In an exemplary embodiment a cryotherapy device includes a catheter body, a proximal end and a distal end; a first lumen; a second lumen; and an ablation element expandable from a first diameter to a second diameter, the ablation element having a surface portion that conforms to the uneven surface topography of the cardiac tissue. The ablation element can include one or more deformable balloon and/or flexible elements. The surface of the balloon can further be shaped by regulation of pressure within the one or more balloons. In an exemplary method, a tissue ablation device is provided and tissue in the left atrium is ablated with the device, whereby the ablation is created by freezing tissue.
