A transaction management system is capable of simply and accurately gathering information about the use of medical products with minimized human errors and automatically executing issuance of invoices of suppliers and restocking of used products on the basis of the results of use of products deposited at medical centers. The system comprises a computer system having an antenna electrically connected to a reader and a medical product encapsulated in a sterilized environment in a package. The package is provided with an IC tag arranged such that signal transmission and/or reception is disabled while the package remains unopened so that the medical product is in the sterilized condition. The IC tag becomes wirelessly communicable with the antenna when the package is opened to remove the medical product. The computer system reads the product information about the medical product from the IC tag now wirelessly communicable with the antenna and, on the basis of the obtained product information, places an order to a supplier for the replenishment of the used medical product through a dedicated line or an external network.

A guide wire includes a first wire located at the distal end of the guide wire, a second wire located at the proximal end of the guide wire and having a flexural rigidity greater than that of the first wire, and a tubular connector for joining the first and second wires. The connector has one or more grooves or slits formed on the distal side of the boundary between the first wire and the second wire. The connector is formed of a material different from the material of the first wire. The proximal portion of the first wire is provided with a thin metal coating. The first wire is joined to the connector by brazing at the portion provided with the thin metal coating.
