Abstract
A medical member having flexibility and strength suitable for application to anastomotic portions, and having effectively improved breaking processability. The medical member includes a mesh-like main body that promotes adhesion of the anastomotic portions, in which the main body includes a breakable portion having a relationship between a breaking strength and a compression elongation percentage, represented by the following formulas (1) to (4): Y ≤ 244734 ( X - Z ) - 1.665 ( 1 ) 0 ≤ Z < 408.216 ( 2 ) X - Z > 0 ( 3 ) 39 ≤ X . ( 4 )
Claims20
A medical member comprising:
- a mesh-like main body that has a plurality of through-holes, the mesh-like main body configured to induce expression of a biological component by being applied to anastomotic portions of a biological organ, and to promote adhesion of the anastomotic portions by the induced biological component passing through the through-holes and being accumulated, wherein the main body includes,
- when a breaking strength of the main body in a direction intersecting with a plane direction is represented by Y, and
- a compression elongation percentage of the main body in the plane direction is represented by X,
