Title:
BIODEGRADABLE POLYMER FOR MARKING TISSUE AND SEALING TRACTS
Document Type and Number:
WIPO Patent Application WO2003093338
Kind Code:
B1
Abstract:
A tissue marker (14) formed of a biodegradable polymer (10) having drug-delivery capabilities is combined with a sealant (12) that encapsulates the tissue marker and which serves to help anchor the tissue marker against migration. The sealant (12) 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.
