Abstract: A novel medical device and a method for delivery of a scaffold for treatment of secondary lymphedema and ischemia is provided. In some embodiments a catheter medical device and a magnetic guidance method are provided for delivering cell-seeded implants for guided lymphatic regeneration.

Abstract: Embodiments of the present invention relate to a therapeutic device (graft) comprising a collagen membrane having an aligned uniaxial or biaxial structure such that mammalian cells plated on the membrane align mainly along the direction of the collagen fibrils. In a further aspect, a graft comprising a substantially tubular body, wherein the body has an exterior surface, an interior surface, and at least one lumen extending therethrough such that a fluid flow through the lumen can direct mammalian cell migration. In a further aspect, mammalian cells or growth and angiogenic factors can be optionally attached to the exterior and/or interior surface of the substantially tubular body. In various aspects, the graft can be used as a vascular prosthesis, a stent, or a nerve regeneration scaffold. Methods of preparing and implanting same are also provided.

Abstract: Described herein are gene-activated fibrillar compositions and methods, processes, devices for the design, preparation, manufacture and/or formulation of thereof which are capable to encode at least one polypeptide of interest. Methods treating a disease, disorder and/or condition in a subject by increasing the level of at least one polypeptide of interest, by administering to said subject the gene-activated fibrillar composition are also disclosed.
