  • Patent number: 10405912
    Abstract: An intravascular catheter for peri-vascular or peri-urethral tissue ablation includes multiple needles advanced through supported guide tubes which expand with open ends around a central axis to engage the interior surface of the wall of the renal artery or other vessel of a human body allowing the injection an ablative fluid for ablating tissue, such as nerve fibers in the outer layer or deep to the outer layer of the vessel, or in prostatic tissue. The system also controls the depth of penetration of the ablative fluid into and beyond the tissue of the vessel wall. The catheter includes structures which provide radial and lateral support to the guide tubes so that the guide tubes open uniformly and maintain their position against the interior surface of the vessel wall as the sharpened injection needles are advanced to penetrate into the vessel wall.

  • Patent number: 10391706
    Abstract: A method of creating a three-dimensional object includes generating a spray from a fluid by stretching the fluid between two diverging surfaces into a fluid filament until the fluid filament breaks into a plurality of droplets and forms the spray, entraining the spray in a carrier gas flow, directing the carrier gas flow toward a target surface through a multi-nozzle array, and repeatedly applying the carrier gas flow on a target surface to form the three-dimensional object by controlling the direction of the carrier gas flow toward the target surface.

  • Publication number: 20190256764
    Abstract: The invention is directed to delayed gelation agents comprising a degradable polymeric cage containing therein one or more gelation agents. The cage degrades in situ, e.g, in an oil reservoir, thus releasing the gelation agent(s), which can then crosslink second polymers in situ to form a gel.

  • Publication number: 20190216493
    Abstract: An apparatus comprises a body assembly, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The shaft extends distally from the body assembly and defines a longitudinal axis. The acoustic waveguide comprises a flexible portion. The articulation section is coupled with the shaft. A portion of the articulation section encompasses the flexible portion of the waveguide. The articulation section comprises a plurality of body portions aligned along the longitudinal axis and a flexible locking member. The flexible locking member is operable to secure the body portions in relation to each other and in relation to the shaft. The end effector comprises an ultrasonic blade in acoustic communication with the waveguide. The articulation drive assembly is operable to drive articulation of the articulation section to thereby deflect the end effector from the longitudinal axis.
