  • Patent number: 9844406
    Abstract: Systems and methods deploy an electrode structure in contact with the tissue region. The electrode structure carries a sensor at a known location on the electrode structure to monitor an operating condition. The systems and methods provide an interface, which generate an idealized image of the electrode structure and an indicator image to represent the monitored operating condition in a spatial position on the idealized image corresponding to the location of the sensor on the electrode structure. The interface displays a view image comprising the idealized image and indicator image. The systems and methods cause the electrode structure to apply energy to heat the tissue region while the view image is displayed on the display screen.

  • Patent number: 9539052
    Abstract: An apparatus treats tissue at or near a sphincter. The apparatus has an elongated member having at least one lumen including an inflation lumen, and a basket assembly including a first and a second arm. An inflatable member is coupled to the inflation lumen and has a deployed and a non-deployed state. In the deployed state, the inflatable member expands the basket assembly into contact with tissue. At least one of the first and second arms of the basket assembly has a fluid lumen having an aperture for conveying a fluid from the basket assembly. A source of fluid is coupled to the fluid lumen for conveyance of fluid through the aperture. The fluid can be, e.g., an electrolytic solution, and/or an anti-infection agent, and/or an echogenic media, and/or a steroid, and/or an anesthetic, and/or a medicament, and/or a tissue cooling agent. The source can be a drug delivery device.

  • Patent number: 8968284
    Abstract: Apparatus and methods are provided for treating female urinary incontinence by applying a form of energy to tissue in the vicinity of the urethra and/or bladder outlet to change tissue compliance without substantially narrowing the urethral and/or bladder outlet lumen. The apparatus comprises an elongated shaft having a means for treating urethral tissue and an expandable member deployable distal of the means for treating. The expandable member is configured to be anchored against the bladder outlet to dispose the means for treating at a desired treatment site in the urethra using only tactile feedback. The means for treating may include a needleless RF electrode, an ultrasound transducer, or a cryogenic probe configured to be advanced through a hollow needle, each of which are designed to reduce or eliminate symptoms associated with urinary incontinence.
