Self extended sutento which includes the body outside manner, and medicine liquation which install the body outside medicine liquation in the medical instrument

摘要

A medical appliance is provided that includes a self-expanding stent; a sheath adapted to enclose the self-expanding stent in an interior space during deployment; and an external body comprising a bioactive agent attached to the self-expanding stent and adapted to lie outside the interior space of the sheath when the self-expanding stent is enclosed in the sheath. The medical appliance may be deployed in a lumen of a human body and the external body may release the bioactive agent. A method of producing a medical device is provided that includes attaching an external body to a stent and coupling the stent to a delivery arrangement. The external body includes a bioactive agent. A medical device is provided that includes a tissue scaffold; a sheath adapted to enclose the tissue scaffold in an interior space during deployment; and an external body comprising endothelial cells attached to the tissue scaffold and adapted to lie outside the interior space of the sheath when the tissue scaffold is enclosed in the sheath.
