International Classification:

US Classification:

Abstract:

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.

US Classification:

434272000, 156242000, 156061000, 264313000

Abstract:

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.

Abstract:

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.
