POROUS BIOABSORBABLE IMPLANT

摘要

An implant for insertion into a breast lumpectomy cavity to serve as a guide for orienting a radiation source relative to the breast lumpectomy cavity, includes a body formed of a bioabsorbable material comprised of chitosan having a porosity sufficient to ensure tissue in-growth before significant bio-absorption of the implant, the body having exterior margins. An interior orientation marker is spaced inwardly from the exterior margins of the body to facilitate relative orientation between the implant and the radiation source.
