MEDICAL MATERIAL FOR IN VIVO IMPLANTATION CONTAINING SOFTENING AGENT AND/OR MOISTURIZING AGENT , METHOD FOR CONTROLLING CONTENT OF SOFTENING AGENT AND/OR MOISTURIZING AGENT IN THE MEDICAL MATERIAL, AND METHOD FOR PRODUCING THE MEDICAL MATERIAL FOR IN VIVO IMPLANTATION

摘要

Provided are a medical material for in vivo implantation which causes no retention of an exudates in the surroundings and yet shows a flexibility; a method for controlling the content of a softening agent and/or a moisturizing agent in the medical material; and a method for producing the medical material for in vivo implantation. When a hybrid medical material for in vivo implantation, which comprises a bioabsorbable material containing a softening agent and/or a moisturizing agent and a non-bioabsorbable porous base material, contains large amount of the softening agent and/or a moisturizing agent, retention of an exudates occurs in the surroundings of the medical material. It is found out that this phenomenon is a side effect of the softening agent and/or a moisturizing agent. To prevent this side effect, a medical material for in vivo implantation in which the content of a softening agent and/or a moisturizing agent is controlled less than 20 wt%; a method for controlling said content; and a method for producing a medical material for in vivo implantation are provided.
