The present disclosure provides a technique capable of ensuring good visibility when introducing an embolic agent and reducing the visibility after introduction. Provided is an embolic agent kit. The embolic agent kit includes: a catheter having an inner cavity; a reaction product of an ethylenically unsaturated monomer and a crosslinking agent, which is filled in the inner cavity; and a priming solution containing a visualization agent and configured to prime an inside of the catheter.

Embolic agent kit

A drug supply device for supplying drug to a living body surface that includes a shaft and a drug holding sheet attached to the distal end of the shaft. The drug holding sheet has a first face that faces distally and a second face opposite the first face that faces proximally when the drug holding sheet is expanded. The drug holding sheet includes folded portions that fold such that the first face is positioned to face radially inward while exposing the second face to an outside environment when the drug holding sheet is in a folded state. A drug is applied on the first face of the drug holding sheet. The drug supply device includes an expandable member on the second face of the drug holding sheet. The expandable member is expandable to cause the drug holding sheet to expand from the folded state into the expanded state.

Drug supply device

A medical apparatus for joining body lumens in a living body includes a puncture member having a lumen, a distal opening portion and a needle tip at the distal end of the lumen. The needle tip can puncture a tube wall of the body lumen to form a puncture site. The medical apparatus includes a tubular member in the lumen of the puncture member that expands radially outward and contracts radially inward and a plunger movable relative to the puncture member to release the tubular member from the distal opening portion of the puncture member. The tubular member expands to be fixed to the puncture site when the tubular member is released from the distal opening portion of the puncture member.

Medical apparatus

The catheter includes a hollow shaft, at least one adhering portion provided on an outer surface of the shaft, and plural protrusions arranged on the adhering portion. The protrusions are configured to increase a contact surface area to show adhesive strength due to a Van der Waals force.

Catheter

A device for treating the lumen of a living body includes a shaft insertable into a blood vessel, and a balloon provided on the shaft and shiftable between a deflated state and an expanded state. In the expanded state, the balloon has a recessed portion configured to form a coating chamber which is substantially blocked between an inner surface of the blood vessels and the device for treating the lumen of a living body, a discharge port provided on the recessed portion to discharge a coating substance toward the coating chamber; and a suction port provided on the recessed portion to apply a negative pressure to the coating chamber.

Device for treating lumen of living body

To provide a fluorescent hydrogel having superior detectability of saccharides such as glucose and minimal invasiveness, a method for producing the same, and a sensor for measuring saccharides using the same. A florescent hydrogel having a structure represented by the following chemical formula 1, a method for producing the same, and a sensor for measuring saccharides using the same. 

Fluorescent hydrogel and method for producing the same, and sensor for measuring saccharides using the same

An apparatus transfers data between a plurality of input/output (I/O) devices and a main storage unit and includes a plurality of channel devices and a channel control unit. Each channel device is provided with a first data buffer for holding data to be transferred to and transferred from an I/O device. The channel control unit has an address register and a second data buffer. An address register is provided for each channel device, and holds an address of the main storage unit at which address the data to and from the I/O device is stored, and the second data buffer holds the data to be transferred to and transferred from the I/O device, which data is accessed based on the address designated by the address register. A data bus is connected between the first and second data buffers, the data bus having a bit capacity larger than that for data transfer between the I/O device and the channel device.
