  • Patent number: 8252010
    Abstract: A method for removing a clot using and inserting a catheter balloon assembly, having proximal and distal ends including a catheter carrying a remotely inflatable occlusion balloon and another catheter carrying a mechanical device for moving a clot, into patient on one side of clot; a balloon-collared sheath, having a collar sheath with proximal and distal ends, the collar sheath having an open interior, and sealing valve for sealing the interior of the collar sheath, and inflatable collar balloon, disposed on the exterior distal end of said collar sheath, inserted on other side of clot; a suction module, having a suction sheath having proximal and distal ends, the suction sheath having an open interior, and sized to be inserted in a vein, attachable to a suction device. The balloons are inflated and the mechanical device is positioned near the clot, toward the balloon collared sheath towards the suction device.

  • Patent number: 6558060
    Abstract: In conjunction with a guidewire, a handheld guidewire lubrication device. The device has a fluid reservoir for storing a lubricating fluid, where the reservoir has an exterior surface with a first and second face portions, and the reservoir is flexible to allow the first and second face portions to be brought into opposition. The first and second face portions have a compressible permeable material positioned on the face portions, and the compressible material is in fluid communication with the interior of the reservoir.

  • Publication number: 20030013997
    Abstract: The invention is a venous pump used to promote circulation in an extremity. It comprises an inflatable chamber, a compression cell, and tubes to carry a fluid between them. The compression cell is designed to be placed underneath the foot so that walking produces a cyclical compression. The inflatable chamber is designed to be secured about a limb. When weight is placed on the foot, fluid is forced into the inflatable chamber which expands and applies pressure to the limb. When weight is removed, fluid is forced back into the compression cell, removing the pressure from the limb.

  • Patent number: 6149584
    Abstract: The invention is a sternal retractor comprising a curved crossbar and a pair of arms perpendicularly attached to the crossbar, at least one of which may slide over the length of the crossbar. Sternum engaging blades extend from the arms in a general direction from the concave side to the convex side of the retractor. The present invention lifts the ribcage, allowing access to the internal mammary artery while decreasing tissue damage associated with current retractors.
