This novel device for endoluminal drug delivery, unlike the conventional stenting, enables direct localized drug treatment and at the same time reduces rupture of blood vessel wall and enables healing without coil interference. The coils can be coated with drug-loaded biodegradable coating or be porous where the pores contain drugs to enable drug or combination of drugs release into aberrant cavities. A combination of drugs transformed liquid into solid can also be delivered. The solid would further form a seal at the cavity mouth to reduce fluid pressure inside the cavities. Moreover, the device can form bonds with surrounding walls to prevent dislodgement. The devices can be fabricated with, but not limited to, biodegradable or bio-soluble materials, which can completely dissolve and further allow the cavity to shrink. The combinations of drugs delivered by the device can strengthen the walls surrounding the cavities.

• Applications in blood vessels.
• For direct localized drug treatment.
• Healing without coil interference.
• Effective and efficient.
