Abstract: An embolic device includes a microcoil having a portion comprising one or more sets of loops. Loops of each of the one or more sets intersect one with another in succession in a cycle, collectively forming a three-dimensional shape. A shape-setting device includes a three-dimensional (3D) body having a curved surface and a plurality of winding members extending from the curved surface of the 3D body and arranged in a plurality of groups. Winding members of each of the plurality of groups are configured to allow a microcoil to wrap around to form a loop, and adjacent groups of winding members share a winding member to allow loops formed by the adjacent groups to intersect one with another. A method of making an embolic device is also provided.

Abstract: The invention proposes a four-port coupler using micro-strip line in combination with ultra-wide-band compensation circuits. It can be applied for communication systems or information machine systems. The main feature of the invention is the structure and the distribution of the components in the compensation circuit to reduce the size of the coupler. The proposed coupler includes: microstrip directional coupler and compensation circuits, in which the microstrip directional coupler consists of one main line and two secondary transmission lines; the main transmission line has two ports: input and output ports; each secondary is connected to a load and a compensation circuit. The compensation circuit is composed of a low-pass filter and two parallel attenuation regulator circuits.

Abstract: Provided are devices and methods for dispensing a multicomponent composition comprised of a mixture of a plurality of different fluid components. A diffuser surface is placed downstream from a plurality of inlets. An outlet extends through the diffuser surface. At least one inlet placed in fluid communication with a source of a pressurized carrier fluid, and each of a plurality of inlets is placed in fluid communication with a source of a different fluid component. Once the diffuser surface receives fluid components, each received fluid component is directed toward the outlet for mixing and dispensing therethrough by the pressurized carrier fluid from the carrier fluid inlet. Typically, the fluid components are maintained in a different flow path on the diffuser surface before mixing.
