  • Patent number: 11819236
    Abstract: A tissue-removing catheter for removing tissue in a body lumen includes a catheter body assembly having an axis and proximal and distal end portions spaced apart from one another along the axis. At least a portion of the catheter body assembly is sized and shaped to be received in the body lumen. A handle is mounted to the proximal end portion of the catheter body assembly and operable to cause rotation of the catheter body assembly. The handle includes internal handle components that interface with the catheter body assembly. The internal handle components provide at least four interface locations spaced axially along the catheter body assembly. A tissue-removing element is mounted on the distal end portion of the catheter body assembly. The tissue-removing element is configured to remove the tissue as the tissue-removing element is rotated by the catheter body assembly within the body lumen.

  • Patent number: 11399935
    Abstract: Transcatheter guidewire delivery systems, catheter assemblies and associated methods for percutaneous guidewire delivery across heart valves are disclosed herein. A catheter assembly configured in accordance herewith includes an elongated tubular component and an alignment assembly at a distal portion of the tubular component and which is adapted to be located at a target location adjacent a heart valve of a patient. In one embodiment, the alignment assembly deploys to a shape set loop configuration with a side port in an open configuration positioned to allow advancement of a guidewire to exit the catheter in an aligned path with a leaflet coaptation region of the heart valve. In another embodiment, the alignment assembly has a plurality of spaced apart side ports that a guidewire may advance therethrough and toward the heart valve. In some embodiments, a wire guide is used to align the guidewire with a selected side port.

  • Patent number: 10433907
    Abstract: Catheters including elements configured to deliver energy to nerves at or near a treatment location within a body lumen. A treatment assembly is transformable between a low-profile delivery configuration wherein a pair of electrodes are in a staggered arrangement relative to each other along the longitudinal axis, and an expanded deployed configuration wherein the pair of electrodes is aligned along an electrode axis that is orthogonal relative to the longitudinal axis.
