Abstract: A method for removing one or more objects or materials from a body lumen includes delivering a tube and an expandable device to the body lumen to a position proximal to the one or more objects or materials. The expandable device is positioned with a lumen of the tube, and the expandable device includes a lumen extending from a distal portion to a proximal portion. The method further includes proximally retracting the tube such that the expandable device remains in the position proximal to the one or more objects or materials, distally advancing the expandable device such that the distal portion of the expandable device at least partially surrounds the one or more objects or materials, at least partially closing a distal end of the expandable device, and moving the expandable device proximally to remove the expandable device and the one or more objects or materials from the lumen.

Abstract: The present disclosure provides a tissue debridement device and describes an example treatment for ANP using the tissue debridement device. The tissue debridement device has a sheath, a distal tip, and a plurality of rotating tines coupled to the distal tip and the sheath. The distal tip can be adjusted to be closer or further from the sheath to change a diameter of the rotating tines, thereby changing a cutting diameter of the tissue debridement device.

Abstract: A cannulation device is adapted to gain access to the patient's common bile duct. In some instances, the cannulation device includes a first guidewire lumen extending through an elongate shaft and terminating at a first oblique guidewire port, and a second guidewire lumen extending through the elongate shaft and terminating at a second oblique guidewire port. In some instances, the cannulation device includes an inflatable balloon that is inflatable from a collapsed configuration to an expanded configuration in which the inflatable balloon is adapted to occlude the patient's pancreatic duct. In some instances, the cannulation device includes an expandable element that is expandable from a collapsed configuration in which the expandable element is disposed within the guidewire lumen and an extended configuration in which a portion of the expandable element extends distally from a guidewire port.

Abstract: The present invention discloses a method of forming a media support wall framework having a graduated through/pore space of the framework wall such that the graduation provides a greater through space in the lowest region of the framework; providing thus an entry plenum pressure differential compensation that compensates for media compaction problems associated with media contained in vertically standing remediation units; thus providing a more equalized passage of a contaminated air or water stream in a radial direction through out the full height of the media bed and assuring more efficient use of the contained media.

Abstract: A support framework for containing a structurally integral, porous remediation media, such as foam or reticulated foam that is used to remediate corrosive vaporous pollutants in a contaminated inlet stream. The support framework is situated within a plenum and comprises a pair of open-lattice weave frameworks made from corrosion resistant fiberglass reinforced plastic “FRP”. The frameworks are of differing diameters and are concentrically aligned such that a media containment section is formed within the open space formed between the inside wall of the outer framework and the outside wall of the inner framework. The open-lattice weave design allows a greater radial flow through the media per unit of time, doing so with less pressure drop and using less energy than the prior art. The use of FRP to form the framework walls allows creation of large units that are suitable for use in municipal and industrial settings, which was not possible previously.

Abstract: The invention involves the creation of a corrosion resistant gas treatment system comprising a unitary housing subdivided into at least two internal sections, the only connection between the first and the following section(s) is a gas only passage channel; the design allows the simultaneous remediation of contaminants from multiply contaminated gas streams in which some of the contaminants require the presence of microorganisms tolerant of widely differing pH and moisture needs for their reduction. The operation is simple and very efficient because the absence of fluid communication between the two sections allows keeping the moisture levels, pHs and microorganism profiles of the two sections specifically optimized for the target pollutants in the gas stream.

Abstract: A RFID-based method and system for conducting a financial transaction is disclosed. The method includes the steps of: (a) communicating to a RFID reader a transaction amount for completing the financial transaction; (b) displaying the transaction amount on the RFID reader; and (c) placing a RFID tag in close proximity to the reader to communicate acceptance of the transaction by the consumer. The system includes a RFID tag and a POS environment which includes a RFID reader capable of communicating with the RFID tag. The RFID reader displays a transaction amount to the consumer. The RFID reader is capable of detecting acceptance of the transaction by the consumer when the RFID tag is placed in close proximity to the reader. The system also includes a processing system which communicates with the POS environment. The processing system completes the transaction.
