    摘要: A hybrid stent prosthesis including a biodegradable tubular body, a first non-biodegradable self-expanding ring coupled to a proximal end of the biodegradable body, and a second non-biodegradable self-expanding ring coupled to a distal end of the biodegradable body. The hybrid stent includes a mechanism for longitudinally compressing the tubular body to increase the radial or hoop strength thereof. The longitudinally compressing mechanism may be protruding elements coupled to and extending radially outward from the hybrid stent or elastomeric compression bands or tethers extending between the non-biodegradable rings. The compression bands may be pre-connected to both non-biodegradable rings prior to stent delivery, or may be connected to one non-biodegradable ring prior to insertion and connected to the other non-biodegradable ring in situ.

    摘要: Methods and apparatus are disclosed for filling a therapeutic substance or drug within a hollow wire that forms a stent. The stent is placed within a chamber housing a fluid drug formulation. During filling, the chamber is maintained at or near the vapor-liquid equilibrium of the solvent of the fluid drug formulation. To fill the stent, a portion of the stent is placed into contact with the fluid drug formulation until a lumenal space defined by the hollow wire is filled with the fluid drug formulation via capillary action. After filling is complete, the stent is retracted such that the stent is no longer in contact with the fluid drug formulation. The solvent vapor pressure within the chamber is reduced to evaporate a solvent of the fluid drug formulation. A wicking means may control transfer of the fluid drug formulation into the stent.

    摘要: An implantable flow restrictor plug is disclosed that is disposed within a deployed endoluminal prosthesis to initially restrict, then gradually restore blood flow through the prosthesis after an angioplasty procedure. Upon initial deployment, the plug has a tubular biodegradable body defining a blood flow lumen therethrough that is sized to effectively reduce the amount of blood flow exiting the prosthesis. An inner surface of the body erodes or biodegrades in vivo to enlarge the plug lumen, thereby gradually restoring blood flow through the prosthesis until blood flow is unimpeded through the prosthesis, i.e., blood flow through the vessel is fully restored. The flow restrictor plug may be attached to the endoluminal prosthesis to be delivered and deployed therewith, or may be formed within a previously deployed prosthesis.

    摘要: Described herein are implantable medical devices that can be coated with polymers and/or bioactive agents with the aid of supercritical fluids and methods for coating the devices. The medical devices described herein can have at least a portion of their surface made of or formed from a porous material. The supercritical fluids are used as a carrier for the bioactive agents described. Once the bioactive agents are carried to the medical device surface, they are sequestered there, preferably in the pores. The supercritical fluid is sprayed onto the medical devices achieving precipitation of the fluid. If appropriate conditions are used in the area of precipitation, bioactive agents can penetrate into the pores of the medical device before coming out of solution and expanding.

    摘要: An implantable flow restrictor device is disclosed for initially restricting, then gradually restoring blood flow through a body vessel after an interventional procedure. A self-expanding annular member having a constricted diameter gives the device a frustoconical configuration that reduces blood flow therethrough upon initial deployment at a treatment site. The annular member is constricted by a plurality of linkages that operate to allow the annular member to gradually expand, thereby transforming the flow restrictor device to a cylindrical configuration that allows unimpeded blood flow therethrough. In one embodiment, expansion of the annular member is achieved via biodegradation of the linkages. In another embodiment, expansion of the annular member is achieved via creep deformation of the linkages. The flow restrictor device may be attached to an endoluminal prosthesis, or may be a separate complementary component that is delivered during an interventional procedure.
