Abstract: A graft for inducing helical blood flow, including a tubular body with fluid inflow and fluid outflow ends, and with inner and outer sidewalls. A lumen extends between the fluid inflow end and fluid outflow end. A compressible chamber is disposed between the outer sidewall and the inner sidewall. The compressible chamber has an incompressible seam that follows a substantially helical path around a longitudinal axis of the tubular body. When internal (e.g., blood) pressure increases on the inner sidewall, a vane element is formed that follows the substantially helical path around the longitudinal axis of the tubular body. The vane element may induce helical blood flow. The width of the compressible chamber may decrease in a compressed state (e.g., systole). The chamber may be filled with a predetermined amount of at least one of a gas, liquid, or vapor. The graft may have a second incompressible seam/vane.

Abstract: A graft having a tubular body having a first end configured for attachment to a first vessel having a first compliance and second end configured for attachment to a second vessel having a second compliance different from the first compliance, and having a plurality of compressible chambers in the wall of the tubular body in which the chamber adjacent the first end of the tubular body is less compressible than the chamber adjacent the second end of the tubular body such that first end of the tubular body substantially matches the first compliance and the second end of the tubular body substantially matches the second compliance.

Abstract: A drug delivery device is provided for directly treating a treatment site. The device allows body fluids to perfuse past the device while it is expanded to increase the amount of treatment time that is possible. The drug is delivered through a hollow helical tube that extends around a support structure. The hollow tube includes a series of lateral holes to allow the drug to directly reach the desired treatment site.

Abstract: A perfusion device and a delivery system for repair of a damaged portion of a body vessel. Perfusion device can include a tubular body that is self-expandable, having a proximal portion, a distal portion, and an intermediate portion. One or more series of barbs can be disposed circumferentially along the intermediate portion. Barbs are capable of penetrating into the tunica intima and tunica media of said vessel wall upon insertion of said device into said body vessel, and not into said tunica adventitia. A graft can be associated with the tubular body. Graft has a proximal end and a distal end, and preferably extends entirely along a luminal wall of the tubular body. Graft may also extend along an exterior surface of the tubular body at the proximal and distal portions. Delivery devices for the perfusion implant and methods of delivering the perfusion implant are also provided.
