  • Patent number: 5224953
    Abstract: A method for the treatment of an obstructive portion of a urinary passageway of a mammal, comprising the steps of providing a stent thermally self-movable between a first condition in which the stent is rigid and generally tubular, and a second condition in which the stent is flexible and compressible, moving the stent in the second condition through a catheter to the obstructive portion of the urinary passageway while maintaining the stent in its second condition by flowing a cool solution through the stent, moving the stent out of the catheter and into the obstructive portion of the urinary passageway, and discontinuing the flow of cool solution, whereby the stent is caused by body temperature, or by the flow of a warm solution, to assume its first condition to hold open the obstructive portion of the urinary passageway.

  • Patent number: 4957492
    Abstract: A method and apparatus for the collection and handling of pathological tissue specimens during evacuative medical procedures, wherein a source of vacuum is used to draw material from a body cavity and into a collection bottle (22). In accordance with the invention, a tissue trap (21) is placed in advance of the collection bottle for filtering out and collecting tissue specimens prior to entry of the evacuated material into the collection bottle. At the end of an operative procedure, the tissue trap is removed from the system and used as a container for handling and transporting the tissue specimens, thereby avoiding the necessity of direct contact with the specimens by medical workers during the collection and transport thereof. In a preferred form of the invention, the collection bottle is disposable and includes a pour spout for emptying the contents prior to disposal of the bottle.
