摘要：
An electrophysiology catheter includes a catheter body and at least one porous electrode. The porous electrode is formed by forming a substrate of a first more noble metal and forming an alloy on the substrate. The alloy includes a second more noble metal and a less noble metal. The alloy is de-alloyed to form a porous matrix consisting essentially of the second more noble metal. The more noble metals can be gold, copper, and/or platinum, while the less noble metal can be silver, zinc, and/or lead.
