Thus, if parts of the means for cleaning 4 come loose during use, these will be degraded by natural processes in the body and will not remain in the body and cause negative body reactions. ## Claims ### Claim 1 (canceled) ### Claim at position 2 -41. (canceled) ### Claim 42 A debridement and/or implant cleaning tool comprising an elongated based member comprising a bioresorbable polymer, and means for cleaning in a cleaning section at a first end of said base member; wherein said means for cleaning is in the form of bristles, wherein said debridement and/or implant cleaning tool comprises an insert for a rotating, oscillating, or ultrasonic handpiece at a second end of the tool; and wherein said bioresorbable polymer is selected from the group consisting of polylactic acid (PLA, polylactide), polyglycolic acid (poly(glycolide), PGA), cross-linked alginates, trimethylene carbonate (TMC), polymers of L-lactic acid, polymers of D-lactic acid, trimethylene carbonate polydioxanone (PDS, PDO), poly(DL-lactide-co-L-lactide) (LDLPLA), poly (DL-lactide-co-glycolid)(DLPLG), poly(glycolide-co-trimethylene carbonate) (PGA-TMC), poly(L-lactide-co-glycolide) (LPLG), poly(e-caprolactone) (PCL), chitosan, collagen, and any combination thereof. ### Claim 43 (depends on 42) A debridement and/or implant cleaning tool according to claim 42, wherein said bioresorbable polymer consists of LPLA, DPLA, and PGA in a weight percentage ratio of about 85:10:5; or LPLA and DPLA in a weight percentage ratio of about 85:15; or LPLA and DPLA in a weight percentage ratio of about 85:15; or LPLA and DPLA in a weight percentage ratio of about 58:42. ### Claim 44 (depends on 42) A debridement and/or implant cleaning tool according to claim 42, further comprising a motor-driven unit, such as a contra-angle handpiece. ### Claim 45 (depends on 42) A debridement and/or implant cleaning tool according to claim 42, wherein said bristles have a length of 0.5-50 mm. ### Claim 46 (depends on 42) A debridement and/or implant cleaning tool according to claim 42 wherein said base member is formed of two or more wires, such as metallic wires, being twisted with each other, and wherein said means for cleaning is in the form of bristles inserted in between the twisted wires. ### Claim 47 (depends on 42) A debridement and/or implant cleaning tool according to claim 42, wherein at least part of the base member between an insert or a handle and the cleaning section comprising the means for cleaning is covered by a protective coating. ### Claim 48 (depends on 42) A debridement and/or implant cleaning tool according to claim 42, wherein the cleaning section is about 5-12 mm long. ### Claim 49 (depends on 42) A debridement and/or implant cleaning tool according to claim 42, wherein the length of the debridement and/or implant cleaning tool, including both the base member and the cleaning section, is about 15-300 mm. ### Claim 50 (depends on 42) A method for preparing a debridement and/or implant cleaning tool according to claim 42, comprising the steps of mixing at least one biodegradable substance with a catalyst, and heating in suitable cast in an injection molding process. ### Claim 51 (depends on 42) A method for preparing a debridement and/or implant cleaning tool according to claim 42, comprising the steps of a) preparing a suspension of at least one bioresorbable polymer in an aqueous solution; b) pouring the suspension of step (a) into a mold; c) allowing the suspension to solidify during heating; and d) cooling to room temperature and removal of the tool from the mold.
