Abstract: A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents. Polymeric materials may be utilized to fabricate any of these devices, including stents. The stents may be balloon expandable or self-expanding. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics.

Abstract: An intramedullary nail structure is formed with opposing dynamization windows, and spacers of a bioresorable material are positioned within the dynamization windows. The dynamization windows are longer than they are wide. The spacers may be integrally formed as a single insert. Tale nail is used with a bone fastener such as a bone screw which is advanced transversely through the bone and into the spacer, preferably in a bicortical attachment with the bone. The bone fastener is smaller across than the dynamization windows, so each spacer spaces the bone fastener relative to its dynamization window. As the spacers resorb, stress (at least in one direction) is increasingly transmitted through the fracture site rather than through the intramedullary nail. The positioning of the bone fastener, the shape and size of the dynamization windows and spacers, and the material of the spacers all allow design control over the type and amount of dynamization seen at the fracture site. Also, because the bone fastener is smallel across than the dynamization windows and spacers, a larger error in placement of the bone fastener is permissible.

Abstract translation: 髓内钉结构形成有相对的活化窗，生物可除去材料的间隔物位于动态窗内。 动态窗口比它们更广泛。 间隔件可以一体地形成为单个插入件。 特征指甲与骨紧固件（例如骨螺钉）一起使用，骨螺钉横向穿过骨头并进入间隔件，优选地与骨的双皮质附件。 骨紧固件比动态窗口更小，因此每个隔离物相对于其动态窗口将骨紧固件间隔开。 当间隔物吸收时，应力（至少在一个方向）越来越多地通过骨折部位传递，而不是通过髓内钉。 骨固定件的定位，动态窗和间隔件的形状和尺寸以及间隔件的材料都允许对在断裂部位看到的动力学的类型和数量进行设计控制。 而且，由于骨紧固件与动态窗和间隔物平行地跨越，因此允许骨紧固件的放置误差较大。

Abstract: A biocompatible material may be configured into any number of implantable medical devices including intraluminal stents. Polymeric materials may be utilized to fabricate any of these devices, including stents. The stents may be balloon expandable or self-expanding. The polymeric materials may include additives such as drugs or other bioactive agents as well as radiopaque agents. By preferential mechanical deformation of the polymer, the polymer chains may be oriented to achieve certain desirable performance characteristics. The stent has a plurality of hoop components interconnected by at least one flexible connector. The hoop components are formed as a continuous series of alternating substantially longitudinally oriented strut members and connector junction struts, whereas the longitudinal strut is connected to the connector junction strut by alternating substantially circumferentially oriented arc members.

In one embodiment of the invention the resulting stent includes one or more members each having at least one component. The component has non-uniform cross-sections to achieve near-uniform stress distribution along the component when the component undergoes deformation.
