Abstract: The invention provides composite materials that form a biocompatible and bioresorbable settable ceramic-forming composition, and that possesses high strength when set and other desirable mechanical properties. The composite materials may include additive materials that provide beneficial advantages in the handling and physical properties of the material. When a hydrated precursor, the composite material is capable of being injected through cannulas for placement in treatment sites. The composite material provided desirable handling properties and sets in a clinically relevant time period.

Abstract: Disclosed are radially expanding debridement tools configured to pass through an access channel present in a first tissue of a living being, expand radially, and create a void in a second tissue of the living being upon being advanced distally through the access channel and into the second tissue while being rotated, wherein the shape of the void comprises at least one step. Further disclosed are debridement systems and methods of treating tissue defects in living beings.
