    Abstract: Provided are systems for applying a polymer fiber matrix to a tubular conduit to create a graft device. The system comprises a polymer solution comprising at least one polymer and at least one solvent; a polymer delivery assembly constructed and arranged to receive the polymer solution and to deliver the polymer fiber matrix to the tubular conduit; a rotating assembly constructed and arranged to rotate at least one of the tubular conduit or the polymer delivery assembly; and a controller constructed and arranged to control the polymer delivery assembly and the rotating assembly. The system is constructed and arranged to reduce the amount of the solvent in the graft device. Methods of applying a polymer fiber matrix with reduced solvent are also provided.

    Abstract: In some aspects, a graft device can include a biodegradable inner layer, an outer layer, a first end portion, a second end portion, and a lumen therebetween. The biodegradable inner layer typically includes an inner surface and an outer surface. The outer layer typically includes a fiber matrix surrounding the outer surface of the inner layer. The graft device can include a reinforced end portion. At least 10% or at least 50% of the graft device can remain after 90 days of implantation. In some cases, at least 10% or at least 50% of the graft device can remain after 180 days of implantation. The graft device can include a kink-resisting element. The graft device can include at least one layer with a dynamic compliance less than or equal to at least one of: 20%/100 mmHg or 5%/100 mmHg.

    Abstract: A graft device for a mammalian patient tubular conduit comprises a fiber matrix surrounding the tubular conduit and a spine comprising a first support portion and a second support portion. At least one of the first support portion or the second support portions can be constructed and arranged to rotate relative to the other to receive the tubular conduit. The first support portion can comprise a first set of projections and the second support portion can comprise a second set of projections that interdigitiate with the first set of projections. Tools for creating the spine and for applying the spine are also provided.
