摘要：
An intravascular mapping and anchoring assembly is disclosed, comprising: a tubular sheath； an expandable anchor comprising a first portion and a second portion, each having a compressed position and an expanded position, the anchor having a fully compressed position in which the first and second portions are disposed in their compressed positions within the sheath； an array of electrodes mounted to the first portion； wherein the sheath is slidable retractable relative to the anchor to release the anchor from the fully compressed position to a mapping position in which the first portion is released from the sheath to an expanded position while the second portion remains in the compressed position within the sheath； and wherein the sheath is further slidable relative to the anchor to further release the second portion to an expanded position.
