Systems and methods for microvascular anastomotic coupler ring delivery device

A device, comprising:

• an elongated body including a proximal portion, a distal portion, and a channel defined axially through the elongated body, the elongated body defining a longitudinal axis extending along a length of the elongated body;
• an actuator in association with the proximal portion of the elongated body;
• an actuation member disposed at least partially within the channel, the actuation member being operable in response to the actuator to translate along a first axial direction relative to the elongated body;
• a pair of coupling arms in association with the distal portion of the elongated body, wherein each coupling arm of the pair of coupling arms includes a free end and a pivotable end;
• and
• a lower post coupling the pivotable ends of the pair of coupling arms such that each coupling arm is operable to pivot about a pivot axis of the lower post between an open configuration and a closed configuration, wherein the pivot axis is substantially perpendicular to the first axial direction;
• wherein the actuation member includes a first wedge and a second wedge configured to guide the pair of coupling arms toward one another upon translation of the actuation member along the first axial direction such that the pair of coupling arms are parallel with one another in a closed configuration;
• and
• wherein the pair of coupling arms removably engage a pair of coupler rings and orient a plurality of pins of the pair of coupler rings towards the proximal portion of the elongated body when in the open configuration.
