1. A post-biopsy cavity treatment implant, comprising:
- a radiopaque element;
a core portion coupled to the radiopaque element, the core portion including a first porous matrix defining a first controlled pore architecture, and a shell portion coupled to the core portion, the shell portion including a second porous matrix defining a second controlled pore architecture that is different from the first controlled pore architecture.

Abstract
A post-biopsy cavity treatment implant includes a radiopaque element, a core portion and a shell portion. The core portion is coupled to the radiopaque element, and includes a first porous matrix defining a first controlled pore architecture. The shell portion is coupled to the core portion and includes a second porous matrix defining a second controlled pore architecture that is different from the first controlled pore architecture.

61. A method of treating a cavity created by a percutaneous excisional procedure carried out through an incision, comprising the steps of:
-
providing a post-procedure cavity implant, the post-procedure cavity implant including a radiopaque element;
a core portion coupled to the radiopaque element, the core portion including a first porous matrix defining a first controlled pore architecture, and a shell portion coupled to the core portion, the shell portion including a second porous matrix defining a second controlled pore architecture that is different from the first controlled pore architecture;
implanting the post-procedure cavity implant into the cavity, and closing the incision.

62. A method of treating a cavity created by an excisional procedure, comprising the steps of:
-
selecting a first biodegradation rate range;
selecting a second biodegradation rate range that is different from the first biodegradation rate range;
providing a post-procedure cavity implant, the post-procedure cavity implant including a radiopaque element;
a core portion coupled to the radiopaque element, the core portion being configured to biodegrade at a first effective rate within the first biodegradation rate range, and a shell portion coupled to the core portion, the shell portion being configured to biodegrade at a second effective rate within the second biodegradation rate range, andimplanting the post-procedure cavity implant within the cavity.
