摘要：
A biodegradable drug stent (100). The stent (100) is tubular and comprises multiple first circular rings (101) that are arranged longitudinally. Each first circular ring (101) is in the sinusoidal waveform in the circumferential direction. The first circular rings (101) are aligned longitudinally. A second circular ring (102) is arranged between every two longitudinally adjacent first circular rings (101). Each second circular ring (102) is formed by connecting multiple rhombuses in a surrounding mode in the circumferential direction. Two connecting arms (13) are connected between the wave crests of the two first circular rings (101) close to the second circular ring (102) longitudinally and the second circular ring (102) respectively, so that the two first circular rings (101), the second circular ring (102) and the connecting arms (13) form multiple honeycomb structures (103) and multiple diamond-shaped structures (105). Each honeycomb structure (103) comprises two diamond-shaped structures (105). After the stent (100) is expanded, the honeycomb structures (103) and the diamond-shaped structures (105) are linked mutually, so that a stable supporting structure is formed and therefore the radial supporting force of the stent is increased.Linvention concerne une endoprothèse de médicament biodégradable (100).
