Publication number: 20240299155Abstract: 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. 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.Type: ApplicationFiled: November 9, 2023Publication date: September 12, 2024Inventors: Mohammed S. El-Kurdi, William R. Wagner, David A. Vorp, John J. Stankus, Lorenzo Soletti, Jonathan McGrath, Yi Hong, J. Christopher Flaherty

Patent number: 4817600Abstract: A blood clot filtration device, for implantation percutaneously, for preventing movement of blood clots within a blood vessel. The device has a head and a plurality of legs extending therefrom. The legs include a first linear leg portion of predetermined length emanating distally from the head generally parallel to the axis of the device; a second multi-angled leg portion of relatively greater length extending generally outwardly from the distal end of the first linear leg portion at an acute angle to the axis, to form, with other second leg portions, a conical aspect, the second leg portion having a series of discrete linear segments arrayed generally tangent to a cone defined by the second leg portions of the set of legs; and a hook portion at the distal end of each the leg extending outwardly, away from the axis in a manner for engaging the blood vessel to fix the position of the device therewithin.Type: GrantFiled: May 22, 1987Date of Patent: April 4, 1989Assignee: Medi-Tech, Inc.Inventors: James K.
