  • Patent number: 7842098
    Abstract: A stent for maintaining an open passageway through a body lumen, such as the prostatic urethra of a male patient, includes an elongated segment including a flexible polymer material bridging a plurality of hoops. The elongated segment defines a lumen extending therethrough and has a distal end. A retention structure may be coupled to the distal end of the elongated segment to inhibit the distal end from migrating when the stent is placed within a body of a patient. The flexible polymer material is disposed between the plurality of hoops, thereby creating hinged members that allow for the spaces between the hoops to expand and contract longitudinally to accommodate prostatic swelling when the stent is placed within the prostatic urethra of the patient.

  • Publication number: 20080064982
    Abstract: Described are a method and biopsy device which includes a tissue cutting arrangement and a cauterizing element. The tissue cutting arrangement is operable to excise a tissue sample from a sampling site. The tissue cutting arrangement defines a sample chamber therewithin for receiving a tissue sample after excision by the tissue cutting arrangement. The sample chamber includes insulated sample contacting surfaces. The cauterizing element is formed on at least a portion of an exterior surface of the tissue cutting arrangement. The cauterizing element is actuatable to cauterize the sampling site after excision of the tissue sample.
