    摘要： A microwave susceptor which includes a dielectric substrate and a dry layer of microwave active coating material overlaying at least a portion of the substrate is provided. The coating material includes a silicate binder and an active constituent and the weight ratio of the silicate to active is about 98:2 or less (i.e. less silicate). The dry layer is electrically continuous and has a surface concentration of active constituent of about 1 gram per square meter or greater. Sodium silicate is preferred as the binder and graphite is preferred as the active constituent. In addition additives such as saccharides, glycerine and plasticizers can be added to inhibit thermal shut down and to increase the flexibility of the dry layer. The susceptor can exhibit moderate heat performance or even high heating performance if desired. A susceptor baking cup, a baking system including a dome shaped cover which can be used to form an enclosure, and a container for frying are all possible uses for this microwave active coating material.

    摘要： A balloon-type gastric band includes a balloon shaped and dimensioned to circumscribe a stomach at a predetermined location. A supply tube is secured to the balloon for fluid communication with an internal cavity of the balloon, wherein the supply tube includes both at least one colored section and at least one clear section for respectively contrasting the supply tube from surrounding tissue when placed within a patient and facilitating identification of leaks within the supply tube. In accordance with an alternate embodiment the supply tube is colored while remaining translucent.

    摘要： An environmentally sensitive hydrogel material swells or collapses in response to a parameter such as pH level associated with consumption of food by a patient. This swelling or collapsing is harnessed to treat morbid obesity or some other condition of the patient. The swelling or collapsing of the hydrogel may be used to tighten a gastric band or gastric valve when the patient starts eating; then loosen the band or valve when the patient is between meals. The swelling or collapsing of the hydrogel may also be used to increase the size of a space occupying device in the patient's stomach when the patient starts eating; then decrease the size of the space occupying device when the patient is between meals. The swelling or collapsing of the hydrogel may also be used to selectively restrict the absorption of nutrients within a patient's gastrointestinal tract, such as in the duodenum.

    摘要： A surgical access device is provided that includes a housing having at least one access port therein for receiving a surgical instrument therethrough, and at least one elongate flexible instrument channel extending from the housing and having a lumen extending therethrough and in fluid communication with the at least one access port in the housing. The instrument channel is adapted to move from a first collapsed configuration in which the channel is sealed to substantially prevent fluid from flowing therethrough to a second expanded configuration upon insertion of an instrument therethrough.

    摘要： Medical devices, and in particular implantable medical devices, may be coated to minimize or substantially eliminate a biological organism's reaction to the introduction of the medical device to the organism. The medical devices may be coated with any number of biocompatible materials. Therapeutic drugs, agents or compounds may be mixed with the biocompatible materials and affixed to at least a portion of the medical device. These therapeutic drugs, agents or compounds may also further reduce a biological organism's reaction to the introduction of the medical device to the organism. In addition, these therapeutic drugs, agents and/or compounds may be utilized to promote healing, including the formation of blood clots. Also, the devices may be modified to promote endothelialization. In addition, various polymer combinations may be utilized to control the elution rates of the therapeutic drugs, agents and/or compounds from the implantable medical devices.
