  • Patent number: 10239071
    Abstract: A cartridge device is provided for applying a fiber matrix to a tubular member such as a saphenous vein graft. The cartridge includes a housing, a tubular member holder, a rotational drive, and a polymer delivery assembly. The housing defines a chamber which surrounds the tubular member holder. The rotational drive rotates the tubular member during the fiber application process.
    Type: Grant

  • Patent number: 9622849
    Abstract: A tubular tissue graft device is provided comprising a tubular member and a restrictive fiber matrix of a bioerodible polymer about a circumference of the tubular tissue. The matrix may be electrospun onto the tubular tissue. In one embodiment, the tubular tissue is from a vein, such as a saphenous vein, useful as an arterial graft, for example and without limitation, in a coronary artery bypass procedure. 5 Also provided is method of preparing a tubular graft comprising depositing a fiber matrix of a bioerodible polymer about a perimeter of a tubular tissue to produce a tubular tissue graft device. A cardiac bypass method comprising bypassing a coronary artery with a tubular tissue graft device comprising a vein and a restrictive fiber matrix of a bioerodible polymer about a circumference of the vein also is provided.

  • Publication number: 20060075963
    Abstract: An apparatus for seeding material in a scaffold member capable of entrapping such seeding material therein is provided. The apparatus may include a chamber having an interior and capable of maintaining a negative pressure and capable of enclosing the scaffold member therein, and a support member for rotating the scaffold member disposed within the interior of the chamber and for introducing the seeding material into the chamber. At least a portion of rotating the scaffold member occurs simultaneously with applying the negative pressure condition to the scaffold member. The seeding material may be passed from the interior of the scaffold member to the exterior of the scaffold member in response to the application of negative pressure such that at least of portion of the seeding material is entrapped in the scaffold member.
