    摘要： A tissue surface treatment apparatus includes a housing having a proximal end, a distal end including a tissue contacting surface, an interior defined by the housing and a handpiece coupled to the housing. The contactinc surface has a plurality of apertures. An energy delivery device including an electrode is positionable in the housing interior. The electrode includes a tissue penetrating distal end in substantial alignment with an aperture. The electrode is configured to be advanced from the housing interior through the aperture and into a target tissue site to define an ablation volume at least partly bounded by a tissue surface. An advancement device is coupled to the energy delivery device and is at least partly positionable within at least one of the housing or the handpiece. The advancement device is configured to advance the electrode from the housing interior into the target tissue site and withdrawal the electrode into the housing interior. A cable is coupled to the housing or the energy delivery device and is configured to be coupled to an energy source.

    摘要： An embodiment of the invention provides a method for detecting and treating a tumor using tissue localized volumetric impedance measurement. The method includes providing an impedance measurement apparatus having a plurality of resilient members deployable with curvature and configured to sample tissue impedance through a plurality of conductive pathways. The apparatus is configured to be coupled to at least one of an energy delivery device, a power supply, a switching device or logic resources. The apparatus is then positioned at a selected tissue site and the impedance array deployed to define a sample volume. The impedance array is then utilized to make impedance measurements through a plurality of conductive pathways. Information from the impedance measurements is then utilized to determine a tissue condition of the sample volume. Energy is then delivered from the energy delivery device to ablate or necrose at least a portion of the tumor.

    摘要： Systems for controlling obesity utilize a number of space occupiers positioned in the stomach to reduce the effective volume of the stomach. Such arrangements provides sufficient stomach volume consumption to induce weight loss, but enable use of space occupiers that are proportioned to minimize the threat of obstruction even if they should migrate into the intestine. In general, numerous small volume space occupiers are placed in the stomach such that the total volume equals or exceeds the single volume of prior art single unit space occupiers. However, each individual space occupier is proportioned so that it will pass without obstruction if it moves into the intestine.

    摘要翻译： 用于控制肥胖的系统利用位于胃中的多个空间占用者来减少胃的有效体积。 这种布置提供足够的胃体积消耗以引起体重减轻，但是能够使用成比例的空间占用者，以尽量减少阻塞的威胁，即使它们应该迁移到肠中。 通常，许多小容量空间占用者被放置在胃中，使得总体积等于或超过现有技术的单个单位空间占用者的单个体积。 然而，每个单独的空间占有者是成比例的，以便如果它进入肠道，它将不会阻塞。
