Abstract: A vibration-type actuator can be miniaturized and can stabilize a pressure state between a driven body and a vibration body. A pressurizing unit applies a pressure force between projections on the vibration body and the driven body.

The pressurizing unit includes an energizing member, its support member, and a transfer member. A length of a contact area between the projections and the driven body is shorter than a length of an area in which the transfer member transfers the pressure force from the energizing member to the vibration body and a length of a contact area between the energizing member and the support member, in a direction perpendicular to the moving direction and to a pressurizing direction by the pressurizing unit.

Abstract: An artificial blood has a trunk portion with both ends connected to blood vessels, and access branch portions and a shunt branch portion branched from the trunk portion. The access branch portions are disposed with a solid column-shaped access port that plugs these branch portions. The access port has a solid center portion and a tube-shaped peripheral portion disposed to surround the center portion. The peripheral portion is harder than the center portion and prevents the needle from deviating from the inside of the center portion. This enables a puncture to be easily made in a therapy in which a puncture is highly frequently made in a blood vessel.

Abstract: An artificial blood vessel has a trunk portion which forms a part of the blood vessel and also has branch portions which are branched from the trunk portion. The branch portions are provided with access ports into which a needle, for discharging liquid out of a human body or introducing the liquid into the human body, is inserted. Tubular reinforcement members integrated with the blood vessel wall of the trunk portion are disposed at positions of the trunk portion, the positions being those from which the branch portions are branched, and at portions adjacent to the positions of the trunk portion. A lateral force at the time of needle insertion is borne by the reinforcement member, and this prevents the trunk portion from deforming. Thus, the configuration prevents the artificial blood vessel from deforming due to a force applied when a needle for discharging liquid from a human body or introducing the liquid into the human body is inserted into an access port of the artificial blood vessel.
