Abstract
According to one embodiment, a tissue penetrating device includes an elongate shaft having a proximal end, a distal end, and a lumen extending there between. A first needle is disposed within the lumen of the elongate shaft and is extendable therefrom between a first configuration and a second configuration. In the first configuration, the first needle is disposed within the elongate shaft's lumen and is substantially aligned with an axis of the lumen. In the second configuration, the first needle extends distally of the elongate shaft's distal end and bends away from the lumen's axis. A second needle is disposed within a lumen of the first needle and is extendable therefrom when the first needle is positioned in the first configuration and when the first needle is positioned in the second configuration. The second needle may be extended from the first needle to penetrate tissue of a patient.
