    摘要： Transmural subsurface interrogation and ablation apparatus and methods are described where tissue to be ablated is monitored while under direct visualization for tissue parameters (e.g., temperature and impedance) prior to, during, or after ablation. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An ablation probe and one or more interrogation needles having sensors are advanced into the tissue to be ablated and monitored. Alternatively, a combined ablation and interrogation probe may be used.

    摘要： Tissue visualization device and method variations are described herein where an imaging hood is temporarily sealed against a region of tissue to be treated while under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. The imaging hood is placed against or adjacent to the tissue to be imaged in a body linen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid is pumped into the hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via all imaging element. Temporary sealing against the tissue can be achieved in a number of ways such as circumferential balloons inflatable within the hood or other sealing techniques. A field of view of the imaging element can be expanded by inflating the balloon beyond the imaging hood.

    摘要： Apparatus and methods for the treatment of atrial fibrillation are described herein where tissue to be ablated may be monitored under direct visualization. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. An ablation probe may be advanced into the contained region where the tissue may be ablated and monitored for changes in color as well as appropriate positioning.

    摘要： Methods and apparatus for creating a working space within a patient's stomach are described. The working space is created by internally spreading or pushing the walls of the stomach apart. Advantageously, such spreading is achieved without pressurizing the patient's stomach, i.e. without injecting a pressurized gas or other fluid directly into the stomach. Diagnostic or therapeutic instruments may be deployed within the working space. It is expected that spreading the walls without pressurizing the stomach will facilitate engagement and/or manipulation of the stomach wall for, e.g., endoluminal treatment of obesity.

    摘要翻译： 描述了在患者胃内创建工作空间的方法和装置。 工作空间是通过内部扩展或推开胃壁而产生的。 有利地，在不对患者的胃进行加压的情况下实现这种扩散，即不将加压气体或其它流体直接注入到胃中。 诊断或治疗仪器可以部署在工作空间内。 预期在不加压胃的情况下扩散壁将有助于胃壁的接合和/或操纵，例如用于肥胖的腔内处理。
