摘要： Devices and methods for treating rhinitis are described where the devices are configured to ablate a single nerve branch or multiple nerve branches of the posterior nasal nerves located within the nasal cavity. A surgical probe may be inserted into the sub-mucosal space of a lateral nasal wall and advanced towards a posterior nasal nerve associated with a middle nasal turbinate or an inferior nasal turbinate into a position proximate to the posterior nasal nerve where neuroablation of the posterior nasal nerve may be performed with the surgical probe. The probe device may utilize a visible light beacon that provides trans-illumination of the sub-mucosal tissue or an expandable structure disposed in the vicinity of the distal end of the probe shaft to enable the surgeon to visualize the sub-mucosal position of the distal end of the surgical probe from inside the nasal cavity using, e.g., an endoscope.

摘要： Surgical devices with integrated visualization and cauterization are described herein where such devices include an elongate structure having a central lumen and an expandable space-creating structure having at least one expandable leaflet mounted in the vicinity of the distal end and is configured for placement within a mammalian body proximate to a therapeutic target. Also included is a proximal terminal having an actuator mounted in the vicinity of the proximal end and is configured to remain outside of said body and provide an actuation mechanism for actuating the space-creating structure. Additionally, at least one fluid connector and said central lumen is in fluid communication between an interior of the expandable space-creating structure and the at least one fluid connector.

摘要： Epicardial access and treatment systems are described herein where such devices may utilize multiple expanding frame members coupled to a flexible or rigid deployment catheter shaft. The multiple frame members may extend distally to collapse into a low-profile configuration and may further expand or open radially to create a working or surgical field under direct visualization and defined by the frame members and surrounding membrane while retracting any surrounding tissue. Moreover, the distal ends of each frame member may be tapered such that the frame members may close tightly relative to one another forming an atraumatic end. Any number of therapeutic tools can be passed through the catheter for performing any number of procedures on the tissue.

摘要： Apparatus and methods for cooling selected regions within a body are described herein. An implantable cooling system is used to cool regions of the brain, spinal cord, fibrous nerve bodies, e.g., vagus nerve, etc. down to about 30° C. to diminish nerve impulses which control seizures or chronic pain. The system includes an implantable unit containing a pumping mechanism and/or various control electronics. It also has a heat exchanger attachable to a tubular body organ, such as the superior vena cava or the inferior vena cava, through which the heat is effectively dissipated. Also included is a heat pump such as a Peltier junction configured to be placed into contact with the region of tissue to be cooled. The heated portion of the Peltier junction is cooled by a liquid heat transfer medium which absorbs the heat from the junction and dissipates it into the tubular body organ.
