摘要： A method for creating tubular inserts is useful for creating custom fitted inserts that correspond to the anatomy of a patient and solve the problem of pressure points, wear of the implant, damage to surrounding tissue, and denting. Surface measurements of the affected portion of a patient's internal cavity are obtained. Those measurements are used to design a core. The core is 3D printed with a soluble material. The core is wrapped with a thin filament or film such that the contours from the core develop on the outer surface of the covering. The covering is hardened and the core is dissolved away, leaving a custom-made implant device that can be deposited in the patient's cavity.
