Abstract
A sacrificial anode stent system comprises a stent having at least one sacrificial anode portion and a vaso-occlusive device. The vaso-occlusive device has at least one portion with a potential different from that of the sacrificial anode portion of the stent.
Claims15
A method for treating a brain aneurysm, comprising:
- providing a sacrificial anode stent delivery system having a stent and a vaso-occlusive device, the stent being coated with at least one therapeutic agent, and the stent comprising at least one sacrificial anode portion wherein the at least one sacrificial anode portion is affixed to the stent;
- providing the vaso-occlusive device with at least one portion with a corrosion potential different from that of the sacrificial anode portion of the stent;
- providing a power source that is in electrical communication with the sacrificial anode portion;
- inserting the stent within a body lumen;
- advancing the stent delivery system to the brain aneurysm;
- deploying the stent within the body lumen;
- placing the vaso-occlusive coil within the brain aneurysm;
- applying a voltage potential from the power source through an electrical pathway to the sacrificial anode portion;
- corroding the sacrificial anode portion.

A method for treating a brain aneurysm, comprising:
- providing a stent and a medical device, each having at least one metal portion, the stent being coated with at least one therapeutic agent;
- providing the metal portion of the stent with a corrosion potential different from that of the metal portion of the medical device;
- selecting from either the stent or the medical device having a sacrificial anode portion of a different corrosion potential from that of a non-sacrificial portion of the stent or the medical device respectively;
- providing a power source that is in electrical communication with the sacrificial anode portion;
- inserting the stent within a body lumen;
- advancing the stent delivery system to the brain aneurysm;
- deploying the stent within the body lumen;
- placing the medical device within the brain aneurysm;
- applying a voltage potential from the power source through an electrical pathway to the sacrificial anode portion;
- corroding the sacrificial anode portion.
