Abstract
A soluble capsule, fairing or adherent material for a stent catheter or other device to inserted into the human body. The capsule, fairing or adherent material is made of a material which dissolves within the body in a convenient time, for example ten or fifteen minutes, allowing a convenient time for placement of the device and protecting the blood vessel from any sharp surfaces of the device.

9. A device suitable for insertion into a lumen of the body, said device comprising:
-
a stent;
a fairing structure mounted on the stent, said fairing structure sized and dimensioned to provide a smooth surface for at least a portion of the stent thereby facilitating intravascular movement of the stent, said fairing structure soluble within the body and having a thickness to allow at least a predetermined minimum amount of time for the intravascular insertion of the stent before the fairing structure dissolves to expose the stent.

16. A method of performing a medical procedure comprising the steps of:
-
providing a catheter having a distal end, said catheter comprising;
a stent mounted on the distal end of the catheter;
a fairing surface surrounding at least a portion of the stent for facilitating intravascular movement of the stent, said covering soluble within the body and having a thickness to allow at least a predetermined minimum amount of time for the intravascular insertion of the stent before the covering dissolves to expose the stent; and
inserting the catheter into a lumen of the body.
