Covered stents

12 January 2017

Medical stent in general refers to a tubular mesh that can be inserted in a natural passage or conduit inside the human body. For various applications, the metal or polymeric mesh is coated with a membrane to improve the stent’s functionality, for example to seal the mesh, to trigger tissue regeneration or to obtain controlled release of drugs.

The versatility of the electrospinning process makes it ideally suited for developing covered stents for a variety of treatments and applications. The porous structure of electrospun membranes can precisely mimic the structure of the extracellular matrix to facilitate a favorable host response, the membranes can provide selective blocking of molecules, and by using biodegradable nano- or microfibers controlled drug release patterns can be realized.
