Patent ID: 8052711

Claim:
An implantable device, comprising: an elongate body including a proximal portion and a distal portion; a fixation mechanism formed about the body, extending from the proximal portion to the distal portion and comprising: a fixation segment positioned in proximity to a distal end of the fixation mechanism and including a deployable lobe, a push tube segment extending from the fixation segment proximally to a proximal end of the fixation mechanism, and an anchor fixedly coupling the fixation mechanism distal end to the body at a location spaced from a distal end of the body such that a portion of the distal portion of the body is located between the fixation mechanism distal end and the distal end of the body; a lubricious interface between the body and a portion of the push tube; wherein the distal portion of the body comprises a bend formed therein, wherein the bend is located between the fixation mechanism distal end and a distal end of the body, and wherein, when the portion of the body about which the fixation mechanism is formed is straight and a longitudinal axis is drawn through the center of that portion, the bend is such that a distal end of the body is deflected by a distance from the longitudinal axis that is greater than a height of the deployed lobe as measured from the longitudinal axis; and wherein the deployable lobe is deployed when the push tube segment is pushed distally.
