    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: 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.

    摘要: Endoprosthesis, such as a stent, includes at least one annular element defined by a first set of strut members interconnected to define apices proximate opposite sides of the annular element. The annular element further includes a foot extension extending between at least one pair of circumferentially-adjacent strut members. The foot extension has first and second foot portions extending circumferentially from corresponding ends of the circumferentially-adjacent strut members, and are contoured to provide at least two areas of flexure. The first and second foot portions are joined at a toe portion of the foot extension, and define a circumferentially-directed apex between the pair of circumferentially-adjacent strut members. Preferably, at least one or more additional annular elements, each defined by interconnected strut members, are provided. The annular elements are generally expandable between a delivery configuration and a deployed configuration. The annular elements are longitudinally aligned and connected at connection locations with connectors, wherein at least one of the connectors is constructed of a bio-absorbable material.

    摘要: Endoprosthesis for delivery in a body lumen is provided. The endoprosthesis includes an annular element defined by a set of interconnected strut members, each strut member including a first end and a second end. The first end of selected pairs of circumferentially-adjacent strut members of the annular element are interconnected to define apices proximate a first longitudinal side of the annular element and the second end of selected pairs circumferentially-adjacent strut members are interconnected to define apices proximate a second longitudinal side of the annular element. At least one of the selected pairs of circumferentially-adjacent strut members has a modulator disposed proximate the apex defined there between, the modulator having a first mode to allow expansion of the annular element from an unexpanded configuration toward an expanded configuration and a second mode to resist contraction of the annular element from the expanded configuration toward the unexpanded configuration.

    摘要: The invention is directed to a delivery system for delivering a medical device. The delivery system includes an inner member having a proximal end and a distal end. The inner member defines a longitudinal axis between the proximal end and the distal end. A tip is formed at the distal end of the inner member. A bumper is freely disposed on the inner member. The bumper has a proximal end and a distal end. A seat is defined between the tip and the distal end of the bumper. Additionally, a sheath is disposed about the inner member, the sheath having a proximal end and a distal end. The sheath is movable from a first sheath position substantially covering the seat, and a second sheath position axially offset to expose the seat. The invention also includes a handle in contact with the proximal end of the inner member.
