Abstract: An expandable medical framework for implantation in a mammalian body comprises a plurality of serpentine bands and connector columns. Each serpentine band comprises alternating straight band struts and turns. Each connector column comprises a plurality of connector struts and connects adjacent serpentine bands. The turns of a serpentine band comprise connected turns and unconnected turns, each connected turn having a connector strut extending therefrom. Each unconnected turn has no connector struts extending therefrom. The serpentine bands at the ends of the framework are each connected to an intermediate serpentine band via four or more connector struts which are equally spaced about the circumference of the expandable medical framework. Each two adjacent intermediate serpentine bands is connected one to the other via two connector struts which are equally spaced about the circumference of the expandable medical framework.

Abstract: A biodegradable stent body is defined by a composite of a biodegradable polymer and a biodegradable metal insert. The composition, geometry, and location of the metal and polymer are selected for desirable stent performance.

Abstract: A stent having one or more beneficial agents which enhance the healing effect of the stent. The agent is positioned within a reservoir. The reservoir dynamically releases the agent when the stent is expanded. The reservoir makes use of various changes in stent shape during expansion to assure proper release of the agent. Agent release can be modulated at various points along the stent and with various rates of release. The reservoirs can also be cooperatively combined with features that enhance stent flexibility, structural integrity, and which prevent recoil.

Abstract: An expandable stent has a plurality of expandable rings formed of a plurality of struts and at least one first connector interconnecting adjacent expandable rings. The plurality of struts include a first strut and the at least one first connector has a first arm. A first portion of the first arm is engaged to a first portion of the first strut so that the first portion of the first arm and the first portion of the first strut define a through hole.
