Reconfigurable design for multiple airway treatments

Examples of devices, systems and methods for treating airway tissue disclosed herein include features that allow a device to change among multiple configurations. This configurability can allow the treatment of different tissue types and/or different locations within the airway. The different configurations may have different mechanical or energy delivery profiles suited for addressing different treatment goals, such as tissue shrinkage versus tissue shaping. Additionally, there may be sensors for determining a current configuration of a device and changing parameters to suit the current configuration.

APPARATUS AND METHOD FOR TREATING RHINITIS

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. 1a surgical probe shaft having an elongated hollow structure with a proximal end and a distal end, wherein the surgical probe shaft is sized for insertion into and advancement within a sub-mucosal space of a lateral nasal wall from within a nasal cavity of a patient;a handle coupled to the proximal end to facilitate handling and positioning of the surgical probe shaft within the nasal cavity;a position indicator disposed in the vicinity of the distal end of the surgical probe shaft to facilitate visual tracking of a position of the distal end of the surgical probe shaft within the sub-mucosal space of the lateral nasal wall; anda cryo-ablation element coupled to the distal end of the surgical probe shaft configured to cryogenically ablate at least one nasal nerve to reduce at least one symptom of rhinitis.. A cryo-surgical probe having a position indicator for treating rhinitis of a patient, the cryo-surgical probe comprising: The present application is a Continuation of U.S. application Ser. No. 14/808,690 filed Jul. 24, 2015, which claims the benefit of U.S. ...

TISSUE RESECTION WITH PRESSURE SENSING

Prostate treatment using fluid stream to resect prostate tissue, thereby relieving symptoms of conditions such as BPH, prostatitis, and prostatic carcinoma. A device having a fluid delivery element is positioned within a lumen of the urethra within the prostate. A fluid stream is directed outwardly from the fluid delivery element toward a wall of the urethral lumen. The fluid delivery element is moved to scan the fluid stream over the wall to remove a volume of tissue surrounding the lumen. The fluid may be combined with therapeutically active substances or with substances that increase resection efficiency. Fluid force may be adjusted to provide selective tissue resection such that soft tissue is removed while harder tissue is left undamaged. In order to gain a working space within the urethra, another fluid may be introduced to insufflate the urethra in the region of treatment. 1. A tissue modification device for the treatment of a tissue , comprising:an elongate element having a proximal end and a distal end, wherein the elongate element is configured to be inserted into the tissue;a first lumen in the elongate element configured to deliver a fluid into a working space in the tissue to flush the working space; anda pressure sensor to measure a pressure of the fluid and maintain the pressure of the fluid within a range;an energy source disposed within the elongate element, wherein the energy source is configured to resect a volume of tissue through the working space; anda second lumen in the elongate element to remove tissue products resected with the energy source.2. The device of claim 1 , wherein the device is configured to maintain a pressure differential between the first lumen and the second lumen to evacuate resected products through the second lumen.3. The device of claim 1 , wherein the second lumen and the pressure sensor are arranged to remove the tissue products with the second lumen while the pressure sensor measures the pressure and the energy source ...
