摘要:
This invention relates to aggregated compositions comprising short peptides, or sub-sequences, of full length VP22 protein for delivery of substances such as nucleic acids and proteins into cells. The invention relates to such compositions in themselves, and to methods for their manufacture and use.

A process of forming a tissue scaffold is described, the process comprising electrospinning polymer fibers from a spinneret onto a tissue scaffold template. In embodiments, the fibers are plasma-treated between the spinneret and the template. The scaffold may be constructed of alternating layers of aligned and randomly oriented fibers. The scaffold may be heat treated to control the mechanical properties of the scaffold, such as density, pore size and pore interconnectivity.

摘要:
Disclosed herein are methods of modifying a nitinol surface by using abrasive blasting techniques. The surface modification can be performed by abrasively blasting the surface and delivering at least one dopant from one or more fluid jets to cause the at least one dopant to impregnate and/or coat the nitinol surface. The nitinol surface can form a portion or all of a medical device, such as an implantable medical device, e.g., a stent.
