Abstract: A catheter system (100) for treating a vascular lesion (106) within or adjacent to a vessel wall (108) includes an energy source (124), a plurality of energy guides (122A) and a system controller (126). The energy source (124) generates energy that is received by the energy guides (122A). The system controller (126) controls the energy source (124) so that the energy is sequentially directed to each of the plurality of energy guides (122A) in an advancing wavefront. The system controller (126) controls a firing rate of the energy source (124) to each of the plurality of energy guides (122A). The system controller (126) can control a firing sequence to the plurality of energy guides (122A) so that the advancing wavefront is generated toward the vascular lesion (106) from near a balloon proximal end (104P) and from near a balloon distal end (104D). The system controller (126) can control the energy source (124) so that the energy from the energy source (124) is alternatively directed to at least two of the plurality of energy guides (122A) at a different firing energy level from one another. The energy level can be based on pulse width, wavelength and/or amplitude of the energy pulse(s).

Abstract: A catheter system for ablation of tissue around a blood vessel, e.g., the pulmonary artery, to reduce neural activity of nerves surrounding the blood vessel. The catheter system includes an elongate shaft having a proximal portion coupled to a handle, and a distal portion. The distal portion includes a transducer and an expandable anchor, which may be actuated to transition between a collapsed delivery state and an expanded deployed state where the anchor centralizes the transducer within the blood vessel. The transducer may be actuated to emit energy to reduce neural activity of the nerves surrounding the blood vessel. Systems and method are further provided for confirming that neural activity of the nerves surround the blood vessel has been sufficiently reduced.

Abstract: Disclosed are systems and techniques for providing laser treatment. For example, a vasculature structure associated with a tissue region can be determined. Based on the vasculature structure, one or more laser parameters for configuring a laser to deliver laser energy to at least one blood vessel within the tissue region can be determined. Laser energy can be delivered to the at least one blood vessel to halt blood flow to a targeted area within the tissue region.

Abstract: A system, method and leak signal discriminator for detection of a leak or mechanical breach in a catheter shaft in the presence of an electrical interferer are disclosed. According to one aspect, a leak signal discriminator having a leak detection circuit is configured to distinguish between a leak signal arising from a leak in a catheter and an interfering signal arising from an electrical interferer. The leak signal discriminator includes circuitry configured to receive from the leak detection circuit a response signal responsive to a test signal the test signal having component signals, each component signal being at a different frequency, and distinguish between a leak and an electrical interferer based at least in part on an evaluation of the response signal
