  • Publication number: 20200246598
    Abstract: A system for manipulating a guide catheter within a patient's nasal passages or sinus cavities includes a guide catheter formed from an elongate flexible member having a lumen passing there through. A wire guide is slidably disposed within the lumen of the guide catheter. The system further includes a steering member fixedly secured to a proximal end of the wire guide and a proximal hub secured to a proximal end of the guide catheter. The system further includes a recessed handle having a first recess for fixedly receiving the proximal hub of the guide catheter and a second recess for receiving the steering member, the second recess being dimensioned to permit axial and rotational movement of the steering member while disposed in the second recess.

  • Publication number: 20200155189
    Abstract: A method for treating OAB in a female patient includes positioning a visualization scope in the patent's vagina; advancing a guide wire through a working channel of a visualization scope, until a tissue penetrating distal tip of the guide wire advances out of the working channel and penetrates a wall of the superior portion of the vagina; continuing to advance the guidewire tip submucosally through the wall of the vagina, until it is positioned within tissue of the bladder trigone; advancing a balloon dilation catheter over the guidewire until a balloon carried on a distal end portion of the balloon dilation catheter is positioned proximate the distal tip of the guidewire within the bladder trigone tissue; and inflating said balloon to form a first dissection plane between separated layers of tissue within the bladder trigone.

  • Patent number: 10058381
    Abstract: A device and method that provides a minimally-invasive approach to performing treatments on soft tissue, such as that found in the bladder. The device is useful for manipulating tissue such that treatment tools can be inserted into the tissue at a controlled depth. In some implementations, the device and method described herein are suited to provide therapy to non-mucosal target tissue (or a target volume of tissue) to modulate bladder function. In an example, energy can be delivered to denervate selected portions of the bladder, such as afferent nerves.

  • Patent number: 9694167
    Abstract: A method of treating a constricted sinus passageway of a patient includes traversing the canine fossa region of the patient so as to form a passageway in the sinus cavity. A cannula is positioned in the passageway. A visualization tool such as an endoscope is passed through a lumen or channel in the cannula to aid in visualization of the anatomical site of interest. A balloon dilation catheter is then deployed through or along the cannula so as to place the balloon within or across the constricted anatomical space (e.g., ostium). The balloon is then expanded so as to expand at least a portion of the constricted anatomical space. Alternative embodiments include the use of an optional guide wire and incorporating a endoscope lumen through the balloon dilation catheter.

  • Patent number: 9278199
    Abstract: A method of treating diseased ethmoid sinuses in a patient with a therapeutic agent includes providing an injection device comprising an elongate member having a proximal end, a distal tip or end, and a lumen extending between the distal tip or end and the proximal end, the proximal end being operatively coupled to a source of the therapeutic agent. The distal tip or end of the injection device is inserted at least partially within an interior portion of an ethmoid air cell. The therapeutic agent is then injected into the interior portion of the ethmoid air cell using the injection device, the therapeutic agent being delivered via the lumen in the elongate member.
