Examples relating to a medical device (100) are described. In an example, the medical device (100) includes a tubular support structure (102) having a plurality of ringlets (202, 204, 206, 208) arranged sequentially along a common longitudinal axis thereof, a plurality of long connecting elements (212) to connect the plurality of ringlets (202, 204, 206, 208). Each of the plurality of ringlets (202, 204, 206, 208) is formed by of plurality of crowns (210) connected along a circumferential direction, each crown (210) being formed by two straight struts (216) arranged in V-shaped configuration. At least one of the plurality of long connecting elements (212) connects adjacent ringlets (202, 204, 206, 208). Additionally, consecutive long connecting elements (212) connecting adjacent ringlets (202, 204, 206, 208) are to form a mirror-reflection of each other about a radial plane of reflection.
