Disclosed are example embodiments of a stent. The stent is formed by cutting cells from a tubular shape. The tubular shape may include multiple distinct areas, including a first area configured to produce a strong radial force to expand, and a second area, adjacent to the first area, configured to produce a smaller radial force to expand. The strong radial force generated by the first area may be designed to provide significant support to the vessel walls, effectively maintaining patency in the targeted region. In contrast, the second area, which generates a smaller radial force relative to the first area, may be optimized to minimize pressure on adjacent sections of a vessel, reducing the risk of injury to those areas. This strategic distribution of radial forces within the stent structure may enable the stent to address varying levels of stenosis, offering both robust support and gentle expansion.

Provided is a male connector connectable to a female connector having an elastic valve body. The male connector comprises: a flow passage pipe member having an opening; an elastic opening/closing part; a biasing part; a housing; and a moving body having a moving body regulation part and holding the elastic opening/closing part. The male connector undergoes a change in configuration from a first configuration in which the opening is closed by the elastic opening/closing part to a second form in which the opening is opened when the flow passage pipe member protrudes from the elastic opening/closing part due to a connecting operation in which the elastic valve body is pressed against the elastic opening/closing part so that, against a biasing force of the biasing part, the elastic opening/closing part and the moving body move toward a proximal side in an axial direction. The moving body regulation part moves radially inward to regulate the movement of the female connector with respect to the elastic opening/closing part. The housing has a housing regulation part that, due to the change in configuration from the first configuration to the second configuration, regulates the movement of the moving body to thereby regulate, via the moving body regulation part, the movement of the female connector.
Provided are a connection state determination method and a connection state determination system that enable provision of work assistance to a medical worker to reduce workloads and human mistakes.

This male connector is connectable to a female connector having an elastic valve body, and has an elastic opening/closing part, a biasing part, a housing, a movable body, and a flow passage pipe member that has an opening in an axially tip side portion. The movable body has a movable body restriction part and a holding part that is for holding the elastic opening/closing part, and changes a form from a first form, in which the opening is closed by the elastic opening/closing part, to a second form in which the opening is opened as a result of protrusion of the axially tip side portion of the flow passage pipe member to the axially tip side from the elastic opening/closing part due to a connection motion in which the elastic opening/closing part and the movable body move to an axially base end side with respect to the flow passage pipe member while resisting to a biasing force of the biasing part resulting from pressing of the elastic valve body to the tip surface of the elastic opening/closing part. The movable body restriction part moves to the radially inner side due to the resistance from the housing generated in association with the connection motion, and moves to the axially tip side with respect to the holding part due to elastic deformation of the movable body in the axial direction, thereby restricting the movement of the female connector to the axially tip side portion with respect to the elastic opening/closing part.
