  • Patent number: 12098638
    Abstract: Provided is a method and system for coalbed permeability-enhancement induced by pressure-relief with mining an extremely thin slice, belonging to the technical field of coalbed permeability-enhancement induced by pressure-relief. The method includes arranging a boundary gateway and a boundary roadway along a mine field boundary, constructing a row of boreholes into the coal seam to run through a conventional development roadway and the boundary roadway, and arranging devices in the conventional development roadway, the boundary roadway, and the row of boreholes to cut the extremely thin stratified coal seam between boreholes, thus creating a mining space in the coal seam, which causes a deformation failure of the coal around the boreholes.

  • Publication number: 20240197392
    Abstract: Examples presented herein illustrate various end effector designs with multiple spines that can expand from a collapsed configuration as the end effector traverses vasculature to an expanded configuration when the end effector is at a treatment site. In some examples, the end effector includes three frame loops which each include a pair of spines. At least one of the three frame-loops can have a bend at a distal end of the end effector so that the spines of the frame loop are not directly opposite each other with respect to the longitudinal axis. In some examples, the end effector includes an inner and an outer frame, each having multiple spines and configured such that one or both of the frames can rotate from an aligned configuration to an unaligned configuration.

  • Patent number: 11864904
    Abstract: Systems and methods for measuring the magnetic fields generated by renal nerves before and/or after neuromodulation therapy are disclosed herein. One method for measuring the magnetic field of target nerves during a neuromodulation procedure includes positioning a neuromodulation catheter at a target site within a renal blood vessel of a human patient near the target nerves, and detecting a measurement of the magnetic field generated by the target nerves. The method can further include determining, based on the measurement of the magnetic field, a location of the target nerves, a location of ablation at the target nerves, and/or a percentage the target nerves were ablated by delivered neuromodulation energy.
