The balloon catheter of the present invention is provided with a balloon base at a front end of a tubular catheter body having a predetermined length. The balloon base includes a cylindrical base having a larger diameter than an outer diameter of the catheter body, and a lumen having substantially the same diameter as the outer diameter of the catheter body is formed on the base over an entire length with both ends opened. A central axis of the lumen is inclined at a predetermined angle with respect to a central axis of the base concentric with a central axis of the catheter body, and an outer peripheral surface is formed in parallel with the central axis of the base. The balloon is provided on the outer peripheral surface of the parallel base to obliquely inflate with respect to the central axis of the catheter body during inflation.

A device for fixing biological soft tissue is endowed with strength and deformation performance for being used as a device for coupling biological soft tissue that has been cut or separated due to an incision or the like during a surgical procedure, and is completely degraded in vivo and discharged after adhesion of the soft tissue or after healing of the incision tissue. The device is composed of a ternary Mg alloy material of Mg&#x2014;Ca&#x2014;Zn. In the Mg alloy material, the Ca and Zn are contained within the solid-solubility limit with respect to the Mg. The remainder is composed of Mg and unavoidable impurities. The Zn content is 0.5 at % or less. The Ca and Zn content has a relationship of Ca:Zn=1:x (where x is 1 to 3) by atom ratio. The crystal grain structure is equiaxed, the crystal grain size according to linear intercept being 30 to 250 &#x3bc;m.

Provided is a spacer for ionizing radiation therapy, which can be easily disposed in a living body, does not require abdominal surgery for removing the disposed spacer after radiation therapy, and can effectively separate a tissue to be treated from other tissues. The spacer for ionizing radiation therapy includes a fiber assembly obtained by three-dimensionally entangling a fibrous material formed of a biocompatible synthetic polymeric material. Specifically, the spacer has a thickness of 1 mm to 100 mm.
