An absorbable occluder (100) comprises a woven net (110) comprising a decomposable polymer fiber having a polydispersity coefficient ranging from 3 to 10, and a weight-average molecular weight ranging from 20,000Da to 800,000Da. The absorbable occluder (100) can prevent a decomposed product of the polymer forming the woven net (110) from being released in a certain timer interval and resulting in severe inflammation in tissues.
