Abstract:
The present invention relates to a vascular embolic material for use in the treatment of an angiotropy of various tumors and a vascular malformation. Specifically, the present invention relates to a vascular embolic material having the specific morphological, physicochemical and radiological characteristics and multifunction in the form of a bead or a sponge comprising a mixture of a hydrophilic polymer material and a metal material. The specific physicochemical and radiological characteristics of the vascular embolic material according to the present invention facilitate its clinical use and aid in the diagnosis before and after the embolization. Further, a local radiation treatment and anticancer treatment is possible and thus the therapeutic effect on said disorders can be enhanced.
Abstract:
A system and method for determining the detachment of an embolic material using a single power supply are disclosed, wherein the determination is made by applying a DC power to an assembly with an embolic material, a sacrificial link and a guiding wire which are serially connected and repeatedly measuring a voltage and current between the assembly and the ground for a plurality of cycles and a plurality of times in each cycle; computing an average of the measured voltages and an average of measured currents; and determining the detachment of the embolic material from the guiding wire based on a change in impedance between the guiding wire and the ground, wherein the change is detected using the present average of the measured voltages, the present average of the measured currents and a previous average voltage which is previously measured for a plurality of times.
Abstract:
A baffle in a coil dialyzer is disclosed which encircles the upper portion of the outer layer of support material wrapped on the dialyzer core. This baffle prevents shunting of dialysate along the space between the dialyzer coil and outer dialyzer casing thereby materially improving dialyzer efficiency.
Abstract:
Disclosed herein is a method for displaying information about the use of a hack tool in the online game. When a game IDentification (ID) is input, a client system accesses a security server, and requests and receives the number of times that one or more hack tools have been used for the game ID. The client system provides the game ID and the number of times that hack tools have been used to a game server so that the number of times that hack tools have been used is shared by one or more gamers who participate in the game provided by the game server. When the client system detects the use of a hack tool, the client system increases the number of times that hack tools have been used for the game ID by 1, and provides the number of times that hack tools have been used to the security server.
