Sutureless, implantable fluid shunting devices and associated methods for controlling the pressure of fluids within anatomical spaces or cavities of the body. The device generally comprises a tube having a diffusion barrier (e.g., diffusion chamber) formed on a proximal end thereof. Fluid which flows through the tube will collect within the diffusion chamber and will diffuse outwardly therethrough. However, the presence of the diffusion chamber will prevent microbes, cells or other matter from interfering with or backflowing through the tube. Additionally, the tube may be provided with a pressure-openable aperture through which fluid from the tube may flow into the diffusion chamber. Such pressure-openable aperture will remain closed, until the pressure of fluid within the tube exceeds a predetermined maximum pressure P_MAX. In this manner, the pressure-openable aperture will limit the amount of fluid drained from the anatomical space or cavity of the body, thereby avoiding hypotony within such anatomical space or cavity. The diffusion barrier of the device is preferably configured to fit between, and to be engaged by, adjacent recti muscles of the eye. Such engagement of the diffusion barrier with the adjacent recti muscles serves to prevent unwanted migration or post-implantation movement of the device, without the need for suturing of the device to the tissue of the eye.

There is provided by this invention a novel apparatus and method of operating a dc plasma process that diverts the power supply current from the plasma at the initiation of an arc, thereby inhibiting energy from flowing from the power supply to the plasma, and then to allow energy to flow again when the power supply re-enables energy flow to the plasma. The diverting means is connected to the output of the power supply to divert current away from the plasma at the initiation of an arc wherein the diverting means is actuated when the arc is detected on the output and diverts the current for a first pre-determined time. The diverting means is released at the end of the first pre-determined time before the current reaches zero wherein current is redirected to the plasma and the diverting means is reactivated at the end of a second pre-determined time in the event the arc is not extinguished.

The CT image uniformization metal artifact correction method includes the specific steps of collecting data, reconstructing images, dividing metal zones, calculating priori images, obtaining re-projection of the metal zones and the priori images, uniformizing projection data, performing four-order total-variation equation correction, reversely uniformizing the corrected data, reconstructing images again and restoring the image metal zones. The CT image uniformization metal artifact correction method can effectively remove metal artifacts, well maintains structural information of metals and the periphery of the metals, and limits secondary artifact from appearing to the maximum extent and the like.

An occlusion device having at least five arms. Though the number of arms is increased, the diameter of each arm is reduced. As a result, the increased number of arms provides the desired tension as the occlusion device is deployed and provides the desired strength to hold the occlusion device in place and properly occlude the defect. At the same time, the reduced diameter of the arms improves the cycle life of the occlusion device. Furthermore, the increased number of arms provides for better sealing across the defect and reduces residual shunting.

Some embodiments of the invention relate to an inhaler device for pulmonary delivery of at least one substance from a drug dose cartridge to an inhaling user, comprising: a first conduit for conducting a carrier airflow to a proximal opening of a mouthpiece for use by the user; a holder configured to position the dose cartridge within the carrier airflow; and a second conduit for conducting a shunting airflow to the mouthpiece without passing through the dose cartridge position. In some embodiments, a controller connected to a valve controls a rate of carrier airflow, for example by controlling the shunting airflow, based on a sensor indication of airflow rate and a target airflow profile.

The invention relates to the technical field of gray release, and provides a gray release management method, device, equipment and system. The method comprises the steps that a gray release managementplatform sets a gray distribution proportion, and synchronizes the gray distribution proportion to a publishing module; when the version distribution is carried out, the version distribution module calculates the target number of the candidate grayscale servers according to the grayscale distribution proportion and the number of the production servers; the publishing module selects a target graylevel server from the candidate gray level servers, and after a new version is published, the publishing module synchronizes the IP address of the gray level server subjected to gray level publishingto the shunting engine; and the distribution engine divides users of each version into a plurality of user groups according to the gray level distribution proportion and the IP addresses of the gray level servers, marks the types of the user groups, confirms the server type corresponding to each user group, and distributes the service data streams of different versions to the corresponding user groups according to the types of the user groups to which the users belong. By adopting the scheme, the intelligent shunting can be realized, and the error probability of manual shunting can be reduced.
