Abstract: Method for ameliorating secondary pulmonary hypertension in a patient including determining a pulmonary vascular resistance (PVR) of the patient suffering from secondary pulmonary hypertension; assessing a change in the PVR in response to a selection treatment; and treating the patient with a pulmonary artery manipulation device to provide pulmonary artery denervation if the patient is determined to suffer from fixed PH, thereby ameliorating the secondary pulmonary hypertension of the patient.

Abstract: Disclosed herein is a therapeutically active agent usable in the treatment of pulmonary arterial hypertension (PAH), for use in the treatment of pulmonary arterial hypertension, as well as methods of treating PAH, said treatment and methods comprising administering such an active agent and effecting pulmonary artery denervation in the subject. In some aspects, a sub-therapeutically effective amount of the active agent is administered. In some aspects, the method is devoid of administering such an active agent for at least one month subsequent to the denervation. Further disclosed is a method of treating PAH comprising determining a responsiveness of the subject to at least one therapeutically active agent usable in treating PAH; and effecting pulmonary artery denervation in a subject responsive to the active agent(s).

Abstract: The present invention, in some embodiments thereof, relates to methods and/or apparatus for measuring the effectiveness of a renal denervation treatment. In some embodiments, a method for determining effectiveness of the denervation treatment comprises tracking at least one of arterial wall movement, arterial blood flow rate, arterial blood flow velocity, blood pressure and arterial diameter at one or more selected locations in the renal artery over time, and assessing the effectiveness of said renal denervation treatment according to results obtained by tracking.

Abstract: According to some embodiments there is provided a method for controlling a treatment effect on blood vessel tissue during an ultrasonic treatment, the method comprising positioning an ultrasonic transducer device in the blood vessel lumen; controlling a treatment effect by controlling fluid flow, wherein controlling comprises deploying a fluid restrictor at a location relative to the transducer effective to block at least a portion of fluid flowing upstream, downstream or adjacent the transducer. According to some embodiments there is provided an ultrasonic transducer device sized for placement in a body lumen, and comprising a fluid restrictor effective to block at least a portion of fluid flowing upstream, downstream or adjacent the transducer. In some embodiments, the fluid is blood.

Abstract: Some embodiments relate to a method of reducing excess mucosa production and/or secretion in the respiratory tract, comprising: introducing into a respiratory tract lumen a device configured for damaging nerve tissue or blocking neural conduction in the surroundings of said lumen, the device comprising a plurality of energy emitters; positioning the energy emitters of the device inside the lumen at a distance from walls of the lumen; and activating the energy emitters to emit energy suitable to damage the nerve tissue enough to suppress parasympathetic nerve activity which causes excess mucosa production and/or secretion.

Abstract: The present invention, in some embodiments thereof, relates to a devices and methods for intravascular denervation and assessment thereof and, more particularly, but not exclusively, to devices and methods for renal denervation. Some embodiments of the invention relate to an intravascular catheter configured for ultrasonic ablation of the tissue, comprising a plurality of piezoelectric transceivers. In some embodiments, an intravascular distancing device is provided, the device adapted for obtaining at least a minimal distance between an ultrasound emitting element and a tissue, such as the blood vessel wall. Some embodiments of the invention relate to assessment of renal sympathetic denervation (RSD) treatment effectiveness. Some embodiments of the invention relate to processing echo of signals, such as processing of signals to characterize physical and/or mechanical properties of the blood vessel.

Abstract: Some embodiments relate to a method of reducing excess mucosa production and/or secretion in the respiratory tract, comprising: introducing into the lumen of the trachea or the lumen of the bronchi a device configured for damaging nerve tissue or blocking neural conduction in the surroundings of the lumen; and activating the device to damage the nerve tissue enough to suppress parasympathetic nerve activity which causes the excess mucosa production and/or secretion.
