摘要：
The disclosure is directed to a resilient implant for implantation into human or animal joints to act as a cushion allowing for renewed joint motion. The implant endures variable joint forces and cyclic loads while reducing pain and improving function after injury or disease to repair, reconstruct, and regenerate joint integrity. The implant is deployed in a prepared debrided joint space, secured to at least one of the joint bones and expanded in the space, molding to surrounding structures with sufficient stability to avoid extrusion or dislocation. The implant has opposing walls that move in varied directions, and an inner space filled with suitable filler to accommodate motions which mimic or approximate normal joint motion. The implant pads the damaged joint surfaces, restores cushioning immediately and may be employed to restore cartilage to normal by delivering regenerative cells.
摘要（中）：
本公开涉及一种用于植入人或动物关节的弹性植入物，以充当允许更新的关节运动的缓冲垫。 植入物承受可变的关节力和循环负荷，同时减少疼痛和改善损伤后的功能或疾病来修复，重建和再生关节完整性。 将植入物部署在准备好的清创关节空间中，固定到至少一个关节骨并在该空间中膨胀，以足够的稳定性模制到周围结构以避免挤压或脱位。 植入物具有沿不同方向移动的相对的壁，以及填充有合适填充物的内部空间，以适应模拟或近似正常关节运动的运动。 植入物可以将损伤的关节表面进行垫片，立即恢复缓冲，并可用于通过传递再生细胞将软骨恢复正常。
