  • 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.

  • Publication number: 20200114153
    Abstract: Devices, systems, and methods are described by which the blood pressure, nervous system activity, and neurohormonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably a baroreceptor located in the carotid sinus. A control system may be used to modulate the baroreceptor activation device. The control system may utilize an algorithm defining a stimulus regimen which promotes long term efficacy and reduces power requirements/consumption. The baroreceptor activation device may utilize electrodes to activate the baroreceptors. The electrodes may be adapted for connection to the carotid arteries at or near the carotid sinus, and may be designed to minimize extraneous tissue stimulation.

  • Patent number: 10335152
    Abstract: Methods are provided for partial aortic obstruction for cerebral perfusion augmentation in patients suffering from global or focal cerebral ischemia. Alternatively, the methods can be used to partially obstruct aortic blood flow to condition the spinal cord to secrete neuroprotective agents prior to abdominal aortic aneurysm repair. Partial obstruction of a vessel can be accomplished by a device comprising an elongate catheter and a distally mounted expandable member. The expandable member may comprise one or two balloons. Other medical devices, such as an angioplasty, stent, or atherectomy catheter, can be inserted distal the expandable member to provide therapeutic intervention.
