[Problem] To provide, using a simple means, a method that can reduce the risk of insufficient post-operation suturing, in surgery and the like. [Solution] A medical apparatus comprising a biodegradable sheet in which a plurality of through-holes are formed, wherein the value of the ratio (D/P) of the hole diameter D to the pitch P of the through-holes is controlled so as to be within the range of at least 0.25 and less than 40. This medical apparatus is useful with an adhesion promoting device for promoting adhesion of a biological tissue. |
