    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： The disclosure describes a hand-held device that utilizes a mechanical lever system to operate the device with a single hand. The mechanical lever system is coupled to a sliding element within the housing of the hand-held device that slides linearly. The sliding element may be attached to another element that is extended, retracted, or rotated in or out of the device. For example, the hand-held device may be used for prostate ablation therapy. The hand-held device may include an ablation needle electrode that is extended out of a catheter and into a tissue of a patient by depressing an extension lever of the mechanical lever system to deliver ablation therapy. Depressing a retraction lever of the mechanical lever system may retract the needle electrode back into the catheter of the hand-held device. Other variations of the mechanical system and applications of the hand-held device are also described.

    摘要： A system that is used to lock an accessory, for example a cystoscope that is locked to a hand held device that provides prostate ablation therapy, within a housing includes a sliding lock device (SLD) which receives and surrounds at least a portion of the cystoscope in an opening. Once the cystoscope is positioned within the SLD, the user may slide a cover to engage a tab of the cystoscope and secure the cystoscope within the SLD and the housing. The SLD also includes a mechanism for prohibiting cystoscope rotation. After the cystoscope is locked, the SLD allows for a defined amount of axial movement to facilitate prostate viewing and the deployment of prostate ablation therapy. Alternatively, the cover may slide in a rotational manner to secure the cystoscope.
