Abstract:
1. A delivery device for deployment of a surgical coil and attachment member, comprising: an elongate deployment shaft assembly including an elongate delivery sheath which includes a delivery lumen, a distal port and an outer sheath disposed about at least a portion of the delivery sheath; a surgical coil which is configured to pass through the delivery lumen in a straightened constrained state and which includes an unconstrained state wherein an elongate element of the surgical coil is formed into an enclosed configuration with an overlapped portion with the elongate element making contact in the overlapped portion; an attachment member including an attachment loop which is disposed adjacent the distal port of the delivery sheath and which is positioned at or near a center of the surgical coil being deployed from the distal port such that the coil passes through and captures the attachment loop upon deployment from the distal port; and an actuator body secured to a proximal portion of the elongate deployment shaft assembly including an actuator configured to advance the surgical coil distally from the delivery sheath.
