Patent ID: 7833223

Claim:
A device for cutting tissue, comprising: a flexible elongate member; a first tissue cutting wire extending along the member having a first constrained portion with respect to the member, a distal portion anchored to the member, and an unconstrained portion that is adjacent to a first bend region on the member; a second tissue cutting wire extending along the member having a first constrained portion with respect to the member, a distal portion anchored to the member, and an unconstrained portion that is adjacent to a second bend region on the member; and a third tissue cutting wire extending along the member having a first constrained portion with respect to the member, a distal portion anchored to the member, and an unconstrained portion that is adjacent to a third bend region on the member, wherein the unconstrained portions of the first, second, and third wires are adapted to be selectively tensioned to move from a delivery configuration to a cutting configuration to effect cutting of tissue.
