摘要： A stent Includes a stent body formed by a strut. The stent body is cylindrically-shaped and extends in an axial direction. The stent body includes a plurality of helical portions and an annular portion. The strut is helically-shaped along the axial direction to form the plurality of helical portions and the strut is annularly-shaped in the circumferential direction to form the annular portion. Each of the plurality of helical portions has a distal end point and a proximal end point. The plurality of helical portions include a first helical portion and a second helical portion adjacent to the first helical portion in the axial direction. The annular portion is disposed between the first and second helical portions in the axial direction. At least one of the distal and proximal end points of the plurality of helical portions is directly connected to the annular portion.

摘要： A stent has mechanical properties changing in a multistage manner and capable of effectively exhibiting functions thereof in response to a period after indwelling. A stent includes linear struts forming an outer circumference of a cylindrical shape with gaps formed therein and a plurality of link sections each containing a biodegradable material and connecting the struts to each other in each of the gaps, includes at least two link sections having different decomposition periods under identical conditions.

摘要： An operation device is configured to remotely operate a medical device including a movement mechanism configured to move an elongated body to be inserted into a living body forward and backward along the longitudinal direction of the elongated body, and includes an endless linear member. The medical device is operated based on a forward and backward movement of the linear member in the endless axis direction along an endless axis.
