    摘要： A position and seal or packing wear indicator for mechanical flow controlling devices such as valves and blowout preventers. For blowout preventers the system includes ultrasonic sensors for each ram and annular blowout preventer of a blowout preventer stack. Each of the ultrasonic sensors is positioned within the wall structure of the valve or blowout preventer and is recessed with respect to the inner wall surface such that a desired echo thereof occurs at the plane of the inner wall surface, thereby rendering the electronic signal processing system capable of accurately and positively sensing the precise positions of the flow controlling devices at all times. Electrical signals from the ultrasonic sensors are converted by an electronic signal conditioner to a usable interface format for transmission through a multi-conductor cable system to a remotely located computer. The computer includes software which generates on its CRT a graphical display of the respective positions of the flow controlling devices. The position detection capability provided by precision spacing of the ultrasonic sensors from the inner wall surface develops sufficient position indicating accuracy that detection of seal or packing wear can be identified. The computer also includes a printer for printing out data such as position indicating data or the graphical display of the CRT and also includes a data port for transmission of data to remote locations via microwave.

    摘要： Methods for evaluating motion of a tissue, such as of a cardiac location, e.g., heart wall, via continuous field tomography are provided. In the subject methods, a continuous field (e.g., an electrical, mechanical, electro-mechanical, or other field) sensing element is stably associated with the tissue location. A property of the applied continuous field is detected with the sensing element to evaluate movement of the tissue location. Also provided are systems, devices and related compositions for practicing the subject methods. The subject methods and devices find use in a variety of different applications, including cardiac resynchronization therapy.

    摘要： The invention provides methods, systems and apparatus for electrosurgically treating tissue particularly within the uterus and prostate. In an exemplary method, a surgical instrument comprising an elongate shaft having a proximal end and a distal end, an active electrode near the distal end, and a return electrode is introduced into the uterus. An electrically conductive fluid is then introduced into the uterus to distend the uterus and to form an electrically conductive path between the active electrode and the return electrode. The active electrode is then contacted against tissue within the body cavity. Current is passed between the active electrode and the return electrode while the active electrode is contacting the tissue. The active electrode is provided with a surface area which is selected to produce a power density sufficient to resect or coagulate tissue. The active electrode is then moved along and through the tissue to remove, coagulate or vaporize the tissue.

    摘要： A method for measuring the conduction velocity of a depolarization wave in a tissue employs a first satellite located within the tissue and a second that satellite is located within the tissue a distance away from the first satellite, e.g., by using the time of depolarization wave as reported from each satellite and the distance to determine velocity of the wave. Also provided are systems and kits that find use in accordance with the invention.

    摘要： A morcellator for removing large masses of tissues during laparoscopic procedures includes a rotationally fixed, axially movable inner tube disposed within a rotating cutting member. The cutting member is often disposed in the annular space between the inner tube and an outer tube. A laparoscopic grasping instrument is inserted through the lumen and draws the tissue proximally through the morcellator. As the cutting member severs tissue, the tissue is drawn into the fixed lumen of the inner tube. This prevents the cutting member from twisting the severed tissue, thereby preventing any degradation of the surgeon's control. A novel valve is provided to prevent loss of insufflation gas when no instrument traverses the lumen. The inner tube can be translated distally to protect tissues and/or other surgical implements against inadvertent contact with the cutting edge of the cutting member.
