Implantable neuroma formation preventing devices

An implantable neuroma formation preventing and/or treatment device configured to prevent formation of and/or to treat traumatic neuroma at two mammalian nerve stumps, the device comprising:

• a lower shell member,
• an upper shell member,
• wherein the lower shell member is provided with:
• open-topped first and second trenches, each having a receiving section that extends from a respective nerve stump entry port of the device and is configured for placing one mammalian nerve stump therein, wherein each first trench and second trench further has an outlet section adjoining said receiving section and configured to receive therein nerve fibres projecting from the nerve stump received in the receiving section,
• an open-topped and open-loop shaped third trench having opposed ends that each adjoin to a corresponding outlet section of the first and second trenches, the third trench being configured to install therein an axonal guiding structure having opposed axon entry faces and being configured to allow for entry of regenerating axons from each outlet section via the respective axon entry face into the axonal guiding structure,
• wherein the upper shell member is configured to be secured onto the lower shell member after placing of each of the mammalian nerve stumps in the respective one of the receiving sections and after the installation of the axonal guiding structure in the third trench, so that the secured upper and lower shell members form a closed shell about the nerve stumps and the axonal guiding structure.
