Implantable device for modulating localized ph at implantation site

An implantable device configured to affect a localized pH at an implantation site, the implantable device comprising:

• a body of the implantable device, the body comprising a base material;
• a first feature coupled to the body of the implantable device, the first feature comprising a first metallic material;
• and
• a second feature coupled to the body of the implantable device, the second feature comprising a second metallic material;
• wherein the first metallic material has a lower electrode potential than the second metallic material such that the first metallic material is configured to be preferentially oxidized over the second metallic material.

An inferior vena cava filter comprising:

• a body comprising a base material;
• a first feature coupled to the body, the first feature comprising a first metallic material;
• and
• a second feature coupled to the body, the second feature comprising a second metallic material;
• wherein the first metallic material has a lower electrode potential than the second metallic material such that the first metallic material is configured to be preferentially oxidized over the second metallic material.
