    摘要： A removable stent system and method for extraction of a removable stent from a target site is disclosed. The removable stent includes a removable stent having a collapsible end and a collapsing element configured for coupling with a removal tool. The collapsing element can be configured as a lasso or can be movable between two positions when deployed at a target site in vivo. The removable stent overcomes disadvantages and limitations of previous types of stents as well as overcoming complications during or following stent deployment in vivo. The removable stent further includes features that increase its ease of use and reduce the maneuvering required of devices or tools used to remove the stent. This then decreases the amount of effort required by the physician, the procedure time, and the level of discomfort experienced by a patient during the procedure.

    摘要： Method and surgical instrument for treating prostate tissue including a surgical instrument having a main body, a needle deployment port, a needle, first and second handles and a lockout release mechanism to limit needle extension. Additionally, a kit includes the surgical instrument, together with a cystoscope, and optionally a syringe and reservoir of ethanol. The method includes needle-less injection and visualizing the ethanol injection by delivering both an echogenic agent and ethanol either by needle or needle-less injection or by providing an ultrasonically visible marker near the tip of the ethanol delivery cannula. The method also includes extending the needle transversely of the instrument housing using a link assembly.
