  • Patent number: 10824729
    Abstract: A local environment verification method, performed by a server of a computer network, includes injecting, into a linear communication orbit, a bundle of information items regarding deployment of a respective local environment verification framework at each of a first subset of nodes in the computer network. The bundle of information items is distributed to a respective node of the first subset of nodes through the linear communication orbit, and used to establish the respective local environment verification framework at the respective node of the first subset of nodes. The respective node of the first subset of nodes is configured to perform a set of local environment verifications using the respective local environment verification framework. The method further includes injecting, into the linear communication orbit, a query message to collect respective local results of the set of local environment verifications from the first subset of nodes.

  • Publication number: 20200288783
    Abstract: An aerosol delivery device includes a receptacle configured to receive a substrate configured to carry an aerosol precursor composition, and a resonant transformer including a transmitter coupling device and a resonant receiver coupling device that is positioned in proximity to the substrate when received in the receptacle. The aerosol delivery device also includes a pulse width modulation (PWM) inverter configured to drive the resonant transformer. The PWM inverter includes a bridge circuit coupled to the transmitter coupling device, and a PWM controller embodied as an integrated circuit and configured to output a PWM signal to the bridge circuit configured to drive the transmitter coupling device to generate an oscillating magnetic field and induce an alternating voltage in the resonant receiver coupling device when exposed to the oscillating magnetic field.

  • Publication number: 20180325652
    Abstract: A system for open surgical repair of a body vessel is described herein. A retention sleeve receives an expandable prosthesis. The sleeve has a delivery and a deployed configuration. In the delivery configuration, the sleeve has at least one overlapped region and the sleeve is sized to retain the prosthesis in a compressed configuration for insertion of ends of the prosthesis into the vessel. In the deployed configuration, the sleeve is moves to a larger cross-sectional area to allow for expansion of the ends of the prosthesis for engagement with the vessel. One or more releasable members are extendable through the overlapped region to retain the sleeve in the delivery configuration. The releasable member is removable from the overlapped region, preferably from the center of the prosthesis, to permit the sleeve to move to the deployed configuration and expansion of the outer ends prior to the center of the prosthesis.

  • Patent number: 10010701
    Abstract: A drainage catheter includes an elongated tubular member and a locking assembly. The locking assembly includes a first protruding element and a collar. The first protruding element is disposed proximal to a port in the tubular member through which a proximal portion of a tension member may exit. The collar is coaxially disposed about the tubular member and has a second protruding element projecting from an interior surface of the collar. The collar is configured for longitudinal sliding movement relative to the tubular member such that the collar may be moved along the tubular member toward the proximal end of the tubular member thereby interacting with the first protruding element and securing the proximal portion of the tension member between the first protruding element and the collar.

  • Patent number: 8915941
    Abstract: Described are methods and systems for treating fistulae and other passageways and openings in the body. In certain aspects, an anchored suture is provided that extends from at or near a first fistula opening and through a fistula tract toward a second fistula opening. Various modes of anchoring may be used in this regard including, in some modes, having the suture extend from a deployed anchoring member positioned in and/or around the first opening. The anchored suture, which has a more slender cross sectional dimension relative to the fistula tract through which it extends, is capable of receiving an optional fill substance therealong in the tract. A fill substance can be or include a variety of biodegradable and/or non-biodegradable objects and materials including flowable and non-flowable materials.
