摘要： Models are made through a process that provides for a bonding mechanism of pre-made PVA parts to create more complex structures. The components are bonded together by wetting the surfaces to be connected with a PVA solution. The components are then adjoined together and bonded through an additional processing or curing, e.g., freeze-thaw cycle. This process can be repeated multiple times to create more complex structures or models. In another embodiment, a textile or fabric type material is used to increase the radial strength of the models. In such an embodiment, a usually thin piece of textile material, such as a nylon fabric, may be placed within the core molding. Liquid PVA then flows through the nylon hosiery or textile material and one or more curing process are then applied, which allows the PVA solution to bond or otherwise adhere with the material.

摘要： Embodiments provide for partially cured, preformed pieces of PVA capable of later being formed into more specific models. The partially cured, pre-made pieces of PVA can take on many forms and shapes. For example, the shape may be a flat, tubular, cone, spherical, or other similar shape. In fact, more complex shapes such as full organs are also contemplated herein. Nevertheless, such pre-molded components are considered common or general shaped in that the particular shape is produced using standard or common molds, and then later formed into a more specific or desired shape. As such, the preformed pieces of PVA are only partially cured or cross-linked such that they can later be formed into the more specific models that then have additional processing (e.g., freeze-thaw cycle) to retain the new shape.

摘要翻译： 实施例提供了可以稍后形成更具体的模型的部分固化的预成型的PVA片。 PVA的部分固化预制件可以具有许多形式和形状。 例如，该形状可以是扁平的，管状的，锥形的，球形的或其它类似的形状。 事实上，这里也考虑了更复杂的形状，例如全器官。 然而，这样的预成型部件被认为是普通的或一般的形状，因为特定的形状是使用标准的或共同的模具制造的，然后形成更具体或期望的形状。 因此，预成型的PVA片仅部分固化或交联，使得它们可以随后形成更具体的模型，然后具有额外的加工（例如冻融循环）以保持新的形状。

摘要： Anatomical models are provided with simulated plaque, lesion, chronic total occlusion, as well as other vascular diseases that more accurately replicate these abnormalities. In such embodiment, the vascular disease may be formed separate from the structured anatomical model. The formed vascular disease material may then be bonded to or within a PVA material in a separate process from forming this simulated vascular disease, thus providing a replicated specific anatomy structure with an abnormality for demonstrating, testing, and/or developing medical functions and/or devices.
