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： 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 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.

摘要： The present invention provides a tissue resection device comprising a handle housing having a fluid infusion lumen. A shaft is reciprocatably mounted to the housing, the shaft having an aperture adjacent to a distal end and a fluid and tissue aspiration lumen extending from the aperture to a proximal end of the shaft. A cutting member is disposed adjacent to the aperture to sever tissue as the shaft is reciprocated, and an imaging mechanism on the housing is oriented toward the cutting member, thereby allowing the attending surgeon to optically direct the removal of body cavity tissue. A chopping mechanism is disposed within the lumen of the shaft to reduce the size of tissues passing through the lumen.

摘要： A multiplexed medical carrier provides for sensing one or more patient parameters and/or delivering energy via separately identifiable effectors. The carrier includes a body and at least two electrical conductors coupled with at least two effectors. Effectors may be any combination of sensors, actuators or both. Sensors may measure such parameters as pressure, oxygen content, volume, conductivity, fluid flow rate, or any other chemical or physical parameters. Actuators may be used, for example, to pace a heart, stimulate muscle or neural tissue, broadcast ultrasonic energy, emit light, heat or other forms of radiation, or deliver any form of energy or substance. A method for collecting medical data from a patient includes interrogating a network of multiplexed sensors residing on parallel conductors in the patient, including addressing a first addressable sensor in the network to obtain data and addressing a second addressable sensor in the network to obtain data.

摘要： A cryosurgical system comprises a compressor unit and a probe assembly. A secondary refrigerant stream from the compressor unit pre-cools a heat exchanger within the probe assembly in a standby mode of operation. After the heat exchange is pre-cooled, a primary refrigerant stream can be passed through the cooled heat exchanger and thereafter expanded within a tissue-contacting portion of the probe assembly to achieve very low temperatures, typically minus 100° C. or lower. After cooling, the refrigerant stream may be passed through the probe assembly with no or partial expansion to warm the tissue-contacting surface of the probe. A probe sheath can be used to provide sterility.

摘要： The present invention provides electrosurgical needles, needle systems, and methods for their use which will allow the surgeon to target a tumor's blood supply. Generally, the invention facilities targeting the bloodflow of the tumor by incorporating a doppler ultrasound transducer into the needle or needle sheath. Preferably, the surgeon will also be able to control the temperature of the needle using an integral temperature sensor to effect maximum transfer of the RF energy into the tissue, thereby maximizing the volume of tissue destroyed. Furthermore, when used (for example) in the treatment of uterine fibroids, the present invention will reduce damage to the serosa by monitoring the uterine surface temperature during myolysis through a temperature sensor integrated into the sheath holding the myolysis needle.
