Abstract
A needle delivery device is described and includes generally, a needle made of a shape memory alloy pre-formed in an unconstrained configuration, such as, for example, an arc or a curved needle. The needle delivery device also includes a needle delivery guide, a suturing guide and a positioning member. The needle has an eye at its leading tip for holding suture material. The needle delivery guide has a needle channel for passage of the needle therethrough. The needle channel is configured to hold the needle in a constrained configuration, for example, in substantial alignment with the longitudinal axis of the needle channel. The suturing guide is pivotally connected to the delivery guide. The positioning member moves the suturing guide between an extended position and a collapsed position, wherein, in the extended position, the suturing guide is configured to stabilize the tissue and guide the needle in its unconstrained configuration and to enable access by, for example, a grasper or other tool, to the suture material.
