  • Patent number: 7335197
    Abstract: 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.
    Type: Grant

  • Publication number: 20070179491
    Abstract: The disclosure describes a method and a system that may be used to provide feedback on the progress of ablation therapy. The system includes a first needle that penetrates a target tissue to deliver radio frequency energy, with or without a conductive fluid, that heats and ablates the target tissue and a second needle that penetrates the target tissue and detects a tissue property indicative of the ablation progress. Temperature, impedance, or another parameter may be the tissue property detected and measured by the system. In addition, more than one sensor may be positioned on the first or second needle. The system may provide real-time monitoring of the tissue property or use the tissue property measurement to automatically terminate the ablation therapy. In particular, the system may be used to treat benign prostatic hypertrophy.

  • Publication number: 20070077827
    Abstract: The disclosure describes a system that is used to lock an accessory within a housing. For example, the accessory is a cystoscope that is locked to a hand held device that provides prostate ablation therapy. The system 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.
