    摘要： A one-piece, single-use disposable device for transurethral needle ablation (TUNA) of prostate tissue to alleviate BPH is disclosed. The device may include a flexible catheter tip including a rigid core and a flexible tip. The device may also include a single use lockout to help ensure that the device is used to perform only one ablation procedure on a single patient. The device may further include a simplified needle deployment mechanism and/or an automatic needle retraction mechanism.

    摘要： Methods and apparatus for ablating a target tissue are discussed. Such methods and apparatus include those that simplify tissue ablation. For example, a tissue ablation device having an actuator, such as a trigger mechanism, coupled to a power source and an electrode is discussed. A single step of engaging the actuator causes the electrode to be introduced into the target tissue and causes energy to be delivered from the power supply to the tissue via the electrode. By way of additional example, a tissue ablation device having an actuator coupled to a fluid source and an electrode is discussed. A single step of engaging the actuator causes conductive fluid to flow from the fluid source to the target tissue location and causes the electrode to be introduced to the target tissue location. The fluid source may be a conductive fluid, such as saline, which may increase the efficiency of ablation. Various other configurations and methods that simplify tissue ablation are also discussed.

    摘要： Delivery elements, including needle electrodes and sheaths of tissue ablation devices, containing a conductivity-enhancing agent are discussed. The delivery elements contain a body member and optionally one or more coating layers. The conductivity-enhancing agent is disposed on or in the body member and/or at least one of the one or more coating layers. The conductivity-enhancing agent is capable of eluting from the delivery element when the delivery element is contacted with bodily tissue or fluid and increases conductivity of the tissue, making tissue ablation more efficient.

    摘要： In general, the invention provides a transurethral ablation device comprising an electrode for delivery of neurostimulation therapy to a patient to prevent or alleviate pain experienced during the course of a transurethral ablation procedure. The device may include a conductive ablation needle that delivers electrical current for ablation of prostate tissue, as well as neurostimulation current to prevent or alleviate pain encountered in response to the ablation current. In this sense, the ablation needle is integrated with a neurostimulation electrode. Alternatively, the device may incorporate a dedicated neurostimulation electrode independently of the ablation needle, either on the needle or on a catheter body that carries the needle.
