BIODEGRADABLE POLYMER FOR MARKING TISSUE AND SEALING TRACTS |
摘要 |
A tissue marker formed of a biodegradable polymer having drug-delivery capabilities is combined with a sealant that encapsulates the tissue marker and which serves to help anchor the tissue marker against migration. The sealant is delivered to a site in dehydrated form and moisture inherent in tissue at the site expands the sealant. The expanded sealant is formed of a hydrogel and is therefore more compatible to the surrounding tissue than the material of the tissue marker. The sealant and the tissue marker are both bioabsorbed over time.
