    摘要： A tissue collection device and method. One embodiment of the device includes a body formed by an elongated member, a pair of inflatable balloons at spaced-apart locations on the body, and one or more collection structures on the body. Inflation lumens extending through the body and coupled to the balloons cause the balloons to move between collapsed and expanded states. The collection structures collect a tissue sample from a collection region between the balloons. In another embodiment the collection structures include one or more of an irrigation lumen and an aspiration lumen having one or more ports opening into the collection region.

    摘要： A system and method for ultrasonically guided endoscopic (EUS) delivery of one or more embolization coils to an internal body site. The embolization coil delivery devices are preferably ultrasonically guided to the selected internal body site after being advanced through the working channel of an endoscope with its distal end located near the selected internal body site. In one aspect, the system and method may be utilized to deploy an embolization coil into a lesion to promote thrombosis and/or prevent bleeding.

    摘要： An apparatus for applying an electrical charge to a charge retentive surface by transporting ions through an ionically conductive liquid and transferring the ions to the member to be charged across the liquid/charge retentive surface interface. The ionically conductive liquid is contacted with the charge retentive surface for depositing ions onto the charge retentive surface via a wetted donor blade supported within a conductive housing, wherein the housing is coupled to an electrical power supply for applying an electrical potential to the ionically conductive liquid. In one specific embodiment, the charging apparatus includes a support blade for urging the donor blade into contact with the charge retentive surface and a wiping blade for wiping any liquid from the surface of the charge retentive surface as may have been transferred to the surface at the donor blade/charge retentive surface interface.
