  • Patent number: 5441539
    Abstract: Apparatus for depositing a cell product, such as endothelial cell product, in a graft and inserting the graft in a vessel is disclosed. The apparatus preferably comprises a tunneler tube that has a hollow portion for supporting the graft therein, apertures to permit the flow of cell product, and a pointed end cap attached to a distal end of the tunneler tube. The apparatus also has a handle connected to the graft and releaseably connected to a proximal end of the tunneler tube that provides an inlet for cell product and outlet in fluid communication with the lumen of the graft. During deposition, the cell product thus flows through the handle, into the graft and exits through the apertures. During insertion, the tunneler tube is manipulated by the handle to enter a vessel, and is then released from the handle and removed to accommodate anastomoses.

  • Patent number: 5372945
    Abstract: Methods and apparatus for collecting and processing tissue to produce an endothelial cell product having a vessel for rinsing, draining, digesting and isolating tissue. The vessel has a rinsing and digesting chamber for containing tissue during processing. An inlet in the rinsing and digesting chamber allows entry of rinsing solution and tissue from a liposuction device. A waste chamber in fluid communication with the rinsing and digesting chamber preferably connects with a vacuum source. An isolation chamber is separated from the rinsing and digesting chamber by a screen. An ampule in fluid communication with the isolation chamber includes a pair of ports controlled by valve devices to be selectively in fluid communication with the isolation chamber. After processing, the ampule isolates a pellet of endothelial cells and the valve devices permit the pellet to be in fluid communication with the ports.

  • Patent number: 5312380
    Abstract: The invention is an endothelial cell procurement and deposition kit for collecting fat from a patient, processing said fat to produce an endothelial cell deposition product, and depositing said product on the surface of a graft, all under sterile conditions established and maintained within the components of said kit comprised of: fat collection means for collecting subcutaneous fat from a patient; digestion means connectable to said fat collection means to maintain sterility during reception of said fat and for retaining said fat under sterile conditions during rinsing and digestion to produce a digested product; endothelial cell isolation means connectable to said digestion means for maintaining sterile conditions during reception of said digested product and for separating and isolating microvessel endothelial cells from said digested product to produce an endothelial cell product; cell deposition means connectable to said isolation means for maintaining sterile conditions during reception of said endothel

  • Patent number: 4923464
    Abstract: An intravascular prosthesis comprises a lining rolled upon itself around an axis so that it is introducible into a vascular lumen. An inflatable channel is included for unrolling the lining when the prosthesis is positioned within the lumen so that the lining may engage the vascular wall to provide support therefor.

  • Patent number: 4705517
    Abstract: An intravascular prosthesis comprises a lining rolled upon itself around an axis so that it is introducible into a vascular lumen. An inflatable channel is included for unrolling the lining when the prosthesis is positioned within the lumen so that the lining may engage the vascular wall to provide support therefor. An occlusion member is provided for occluding the vascular lumen, when the lining is unrolled, by preventing blood from passing through the prosthesis.

  • Patent number: 4662885
    Abstract: An intravascular prosthesis comprises a lining rolled upon itself around an axis so that it is introducible into a vascular lumen. An inflatable channel is included for unrolling the lining when the prosthesis is positioned within the lumen so that the lining may engage the vascular wall to provide support therefor. A filter is provided for filtering the blood which passes through the prosthesis when the lining is unrolled.
