    Abstract: An apparatus for sodding onto the inner lumenal surface of a synthetic graft of harvested and concentrated microvessel endothelial cells from liposuctioned fat tissues, which harvested cells are formed into a "pellet" of isolated endothelial cells in loose aggregations, includes a sodding tube having a single rigid outer wall bounding a sodding chamber. A filter pack assembly is provided to communicate the pellet of cells from a processing vessel to the graft. This filter pack assembly includes a series of successively finer filter members cooperatively defining a series of turbulent-flow chambers in which aggregations of cells too large to pass through a particular filter are exposed to liquid flow turbulence which is effective to break up the aggregations. A check valve assembly ensures that liquid flow is unidirectional so that sodding of the cells onto the inner lumenal surface of the graft is not interfered with by possible liquid reflux, and sodded cells are similarly not dislodged from the graft by such liquid reflux.

    Abstract: This disclosure includes a method for generating a functional hybrid bioprosthesis. Tissue formed naturally of interstitial collagens is treated to kill native cells and remove potentially immunologically active soluble molecules. Then it may be treated sequentially with extracellular matrix adhesion factor, extracellular matrix glycosaminoglycan, and growth factor appropriate to the cell type required to function within the matrix, and incubating the transplant tissue matrix with cells that are either allogeneic or autologous for the recipient thereby imparting to the matrix the characteristics of the cell type and tissue selected. Tissues with a variety of functional bioactivities can thus be formed in vitro prior to graft transplantation or implantation which will exhibit reduced or no stimulation of an immunological response in the recipient.

    Abstract: A method for polishing radially expandable surgical stents is disclosed where fluid abrasive media M flows over surfaces of the stent (10) causing the surfaces of the stent (10) to be polished and streamlined. The stent (10) is temporarily provided with cylindrical support ends (20), which are not radially expandable to support the stent (10) during the polishing process. An interior polishing fixture (100) is provided which has cylindrical chambers (135) therein adapted to receive a stent (10) therein. Fluid abrasive media M then flows into bores (108) in the fixture (100) leading to the cylindrical chambers (135) and adjacent the inner diameter surfaces of the stent (10). Surfaces of the stent (10) forming the outer diameter are polished by placing the stent (10) within an exterior polishing fixture (200) which has a cylindrical recess (220) therein. The cylindrical recess (220) has a diameter greater than a diameter of outer surfaces of the stent (10) and includes a cylindrical shaft (270) passing axially through the cylindrical recess (220) upon which the stent (10) is located. Slanted bores (208) pass through walls of the exterior polishing fixture (200) and into the cylindrical recess (220), directing the abrasive media M adjacent exterior surfaces of the stent (10) and causing polishing of the exterior surfaces of the stent (10). The direction of abrasive media M flow can be reversed to make streamlining of segments of the stent (10) occur in a symmetrical fashion. After polishing of the stent (10) is completed, the cylindrical support ends (20) are removed and the stent (10) is ready for implantation and radial expansion within a body lumen L. When polished and streamlined, the radially expandable surgical stent (10) more effectively supports a body lumen L without excessive thrombus, restenosis and other medical complications.

    Abstract: An improved method of making a medical device having immobilized heparin on a blood-contacting surface in which heparin is admixed with sufficient periodate to react with not more than two sugar units per heparin molecule in a buffer solution having a pH in the range of about 4.5-8. This mixture is reacted for at least 3 hours while protected from light and is then applied to the immobilized amine groups. This is an improvement over the prior art methods which included using an excess of periodate and then stopping the reaction at a desired point by the addition of glycerol since the conversion of only a few of the natural functional groups to aldehydes better preserves the antithrombotic bioeffectiveness of the heparin molecules bound to the surface. The invention also avoids the prior art steps of drying and reconstituting the heparin by providing a reacted mixture of heparin and periodate that can be stored as a stable liquid and applied directly to the aminated surface several days later.

    Abstract: An implanted device such as a stent is provided which is capable of holding an induced charge of sufficient magnitude that the device may, by electrostatic means, attract the bioactive material to itself. The charge, either positive or negative, or relative to the bioactive material sufficiently positive or negative, is deposited into the implantable device via an exterior induction coil. The implantable device itself becomes an introduced "dosage form", becoming part of a biologically closed electric circuit, through which the bioactive material is attracted to the implanted device.
