    摘要： An actuable truss with ordered or disordered planar or strut elements or pore walls may be seeded with tissue cells, wherein application of a magnetic field may result in mechanical strain on the cells and increased fluid flow in and out of the truss structure. Modified polymers, such as γ-Fe2O3/PLGA, may be used to form actuable scaffolds suitable for tissue engineering. It is also disclosed a device with a trap-door that may be remotely actuated by applying a magnetic field. Such a device may be employed to deliver and control the release of other micro-devices or materials such as drugs to a specific location inside the body of a human or an animal.

    摘要： A tissue illumination system and a method for harvesting a section of a blood vessel from a patient's body for further use. The tissue illumination system includes a light catheter inserted into a lumen of the blood vessel section to illuminate the vessel section and vessel side branches with an intensity which is visible to the physician from an exterior of the vessel section.

    摘要： A system for hemodynamic simulation comprises a vessel having properties of a blood vessel, a reservoir containing a quantity of fluid, tubing connecting the vessel and reservoir, and at least one pump for circulating the fluid within the system. Fluid can be tissue culture medium or blood analog fluid, and the vessel may include mammalian cells attached to its inside. A drive system, comprising two reciprocating drive shafts that are coupled by a cam, enables the uncoupling of pulsatile flow and pulsatile pressure to provide independent control over wall shear stress and circumferential strain. The shaft drives two pumps that are 180 degrees out-of-phase and are connected upstream and downstream of the vessel, and effect this uncoupling.
