loaded non - bioabsorbable tissue support 410 embedded within a bioabsorbable tissue support 140 . the spring - loaded non - bioabsorbable tissue support 410 can be an elastic sheet or an elastic mesh that is compressed into a shape surrounding the cavity 109 . the spring - loaded non - bioabsorbable tissue support 410 is in a “ spring - loaded ” shape , which refers to a non - equilibrium shape for an electric structure that returns , upon removal of a constraining force , to a different shape . the bioabsorbable tissue support 140 constrains the spring - loaded non - bioabsorbable tissue support 410 in the spring - loaded shape . in other words , the spring - loaded non - bioabsorbable tissue support 410 is a non - bioabsorbable tissue support including an elastic material that is spring loaded in a compressed state by the bioabsorbable tissue support 140 . the spring - loaded non - bioabsorbable tissue support 410 is self - expanding , and the expansive force of the spring - loaded non - bioabsorbable tissue support 410 is counterbalanced by the bioabsorbable tissue support 140 before the bioabsorbable tissue support 140 is absorbed by a tissue 30 . the bioabsorbable tissue support 140 can be formed on the outer surface of the spring - loaded non - bioabsorbable tissue support 410 . alternatively , the spring - loaded non - bioabsorbable tissue support 410 can be inserted into the cavity 109 of a device such as the exemplary devices illustrated in fig1 a - 1f , 3a - 3f , 4a , and 4b . in one embodiment , the spring - loaded non - bioabsorbable tissue support 410 can be present only within the elongated portion of the devices of the present disclosure , and not present in a pointed tip portion or in an end plate . the eighth exemplary device 800 can be inserted within the through - hole in the tissue 30 employing the methods illustrated in fig2 a - 2d . the spring - loaded non - bioabsorbable tissue support 410 is configured to expand during bioabsorption of the bioabsorbable tissue support 140 and to conform to a target shape upon release of stress in the elastic material . the target shape may , or may not , be a circular shape . after the insertion of the eighth exemplary device 800 in a through - hole of a tissue 30 , the stress in the spring - loaded non - bioabsorbable tissue support 410 is gradually released during the bioabsorption of the bioabsorbable tissue support 140 , which may take a time period ranging from 1 week to 8 weeks . fig1 b illustrates the configuration around the through - hole after the bioabsorbable tissue support 140 is absorbed into the tissue 30 and the spring - loaded non - bioabsorbable tissue support 410 is expanded to become a relaxed non - bioabsorbable tissue support 410 ′ after relief of the stress built into the spring - loaded non - bioabsorbable tissue support 410 . the through - hole in the tissue 30 may be enlarged during the process of the expansion of the spring - loaded non - bioabsorbable tissue support 410 , and the expansion process stops when the spring - loaded non - bioabsorbable tissue support 410 becomes the relaxed non - bioabsorbable tissue support 410 ′. referring to fig1 a , a ninth exemplary device 900 of the present disclosure includes a spring - loaded non - bioabsorbable tissue support 410 embedded within a bioabsorbable tissue support 140 as in the eighth exemplary device 800 . the ninth exemplary device 900 can be formed and installed in a through -

circular shape . specifically , the spring - loaded non - bioabsorbable tissue support 410 is configured to expand during bioabsorption of the bioabsorbable tissue support 140 and to conform to a target shape upon release of stress in the elastic material . after the insertion of the eighth exemplary device 800 in a through - hole of a tissue 30 , the stress in the spring - loaded non - bioabsorbable tissue support 410 is gradually released during the bioabsorption of the bioabsorbable tissue support 140 , which may take a time period ranging from 1 week to 8 weeks . the spring - loaded non - bioabsorbable tissue support 410 gradually changes its shape during the bioabsorption of the at least one bioabsorbable material of the bioabsorbable tissue support 140 . during the shape change of the spring - loaded non - bioabsorbable tissue support 410 , the spring - loaded non - bioabsorbable tissue support 410 , still containing unrelieved stress , applies pressure at selective regions of sidewalls of the tissue 30 to prevent growth of new tissues therefrom while removing pressure at some other regions of the sidewalls of the tissue 30 to facilitate growth of new tissues therefrom . the growth of new tissues can be thus molded to induce formation of a target shape for the through - hole in the tissue , which can have peripheral surfaces of an arbitrary shape . the through - hole in the tissue 30 may be enlarged at selective regions during the process of the expansion of the spring - loaded non - bioabsorbable tissue support 410 , and may shrink at other selective regions during the process of the expansion of the spring - loaded non - bioabsorbable tissue support 410 . the molding process for the shape of the through -
