    摘要: A device for treating disease along a main vessel and at least one branch vessel extending from the main vessel includes a branch member for deployment in the branch vessel, the branch member having a branch lumen; and a main body for deployment in the main vessel. The main body has a generally tubular wall extending generally longitudinally between opposite first and second ends. The wall has an internal surface defining a main lumen and an opposite outer surface. The wall has a recessed portion that is recessed relative to the outer surface of the wall and positioned between the first and second ends of the main body. The main body has an opening formed in the recessed portion of the wall for receiving the branch member therethrough such that the branch lumen is in fluid communication with the main lumen.

    摘要: A system for treating an aneurysm includes a first double-walled filling structure having an outer wall and an inner wall. The filling structure is adapted to be filled with a hardenable fluid filling medium so that the outer wall conforms to an inside surface of the aneurysm and the inner wall forms a generally tubular lumen to permit blood flow therethrough. The inner wall comprises a blood contacting layer and a reinforcing layer. The reinforcing layer prevents circumferential creep or elastic expansion of the lumen.

    摘要: A bioartificial device, such as a bioartificial pancreas, for implantation in a patient's vascular system. The bioartificial pancreas includes a scaffold adapted to engage an interior wall of a blood vessel, a cellular complex support by the scaffold and extending longitudinally within the interior cavity of the scaffold so as to be exposed to the blood flow when the scaffold is engaged with the blood vessel, the cellular complex support comprising one or more pockets bordered by thin film; and cellular complex comprising pancreatic islets disposed in the one or more pockets, the thin film being adapted to permit oxygen and glucose to diffuse from flowing blood into the one or more pockets at a rate sufficient to support the viability of the islets. The invention also includes methods of making and using a bioartificial pancreas.

    摘要: The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.
