摘要： The disclosure describes a method and a system that may be used to provide feedback regarding the flow of fluid during ablation therapy. The system includes a generator that generates energy to ablate at least a portion of a target tissue, a needle that delivers the energy to the target tissue, a return electrode that receives energy dispersed from the needle, a catheter that houses at least a portion of the needle, a pump that delivers a fluid to the target tissue via the catheter, a sensor that detects a fluid parameter indicative of at least one of flow or pressure of the fluid, and a processor that analyzes the fluid parameter detected by the sensor. The sensor may be located between the pump and the target tissue. The fluid parameter detected by the system may be pressure or flow. The system may be used to treat benign prostatic hypertrophy.

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.
