Abstract: Provided is a magnetic actuation system controlling a magnetic microrobot, a magnetic actuation catheter, or a guide wire by using a magnetic field, and more particularly, a magnetic actuation system compatible with a C-arm that is applied to the C-arm, which is a mobile X-ray fluoroscopy device, in order to enable control of the microrobot or a catheter treatment in a human body by using the C-arm.

Abstract: Provided are a magnetic actuation device using a permanent magnet which may generate a magnetic field for a long time with lower power and lower heat by using the permanent magnet, and a system using the same. The magnetic actuation device may utilize the plurality of permanent magnets for controlling an alignment direction with two degrees of freedom to thus exclude an actuation element limiting space utilization, such as a robot arm, thus allowing an operator using a medical device to perform a safe procedure on a patient.

Abstract: Provided is an aspiration catheter having a tubular shape and used to remove an embolus or a thrombus by being inserted into a blood vessel, and more particularly, a steerable and expandable aspiration catheter which may apply an effective aspiration force to an embolus or a thrombus by steering a distal tip of the catheter in a three-dimensional direction and expanding a diameter of the tip.

Abstract: Carbon-containing nickel-particle powder is provided. The carbon-containing nickel-particle powder has improved shrinkage property when fired due to the presence of carbon. Also, the carbon-containing nickel-particle powder has a very restricted degree of forming agglomerates.

Abstract: Disclosed herewith is a compressor with mufflers. The compressor comprises a drive unit, a compression unit, at least a pair of exhaust mufflers, a coolant exhaust conduit, and a connecting conduit. The drive unit generates power. The compression unit sucks, compresses and exhausts coolant using power transmitted from the drive unit. The exhaust mufflers temporarily store coolant exhausted from the compressing unit. The coolant exhaust conduit is connected to one of the exhaust mufflers to guide the exhaust of coolant to the outside. The connecting conduit connects the exhaust mufflers to each other to cancel out noises during the recombination of divided coolant in one of the exhaust mufflers.
