  • ELECTROSURGICAL DEVICES WITH A SINGLE CONDUCTIVE TUBULAR ELEMENT FOR ACCESSING ANATOMICAL STRUCTURES
    Publication number: 20210282845
    Abstract: An electrosurgical medical device may include a conductive tubular element disposed about an outer surface of an elongate tubular member at a distal portion of the tubular member. The conductive tubular member may be delivered to a treatment site of a gastrointestinal (GI) tract of a patient and electrically activated. While electrically activated, the conductive tubular element may create an opening in a wall of the GI tract and a pseudocyst. After the incision is made, the conductive tubular element may be withdrawn from the treatment site and a drainage device may be positioned in the incision for drainage of the pseudocyst.

  • Collapsing structure for reducing the diameter of a stent end
    Patent number: 9271854
    Abstract: A collapsing structure for collapsing the crowns of a stent and method of use thereof are described. The collapsing structure comprises an inner filament engaged to an outer filament. The outer filament is interwoven through at least a portion of the crowns of the stent end so as to create a plurality of loops. The inner filament is interwoven through at least a portion of the loops of the outer filament. Pulling on the inner filament causes the loops of the outer filament to be pulled radially inward, thereby pulling the crowns towards each other to collapse the stent end.
