A wound closure device for promoting hemostasis includes a polyhedral body comprising a proximal body end portion and a distal body end portion, including a suture channel horizontally extending through the proximal and distal body end portions, the suture channel containing proximal and distal suture channel openings. An actuator system includes a suture engagement member configured to selectively facilitate axial movement or release of one or more sutures through the channel in an open configuration, and to facilitate securement of suture(s) in the channel in a locked configuration. The proximal body end portion includes a face configured to contact a body surface, anchoring the body to the body surface when suture(s) are secured under tension by the engagement member in the locked position. Once the sutures are secured, the device lends itself to hands-free anchoring until hemostasis is achieved. The device and sutures may then be removed that same day, shortly thereafter.

1. A cutaneous wound closure device comprising: a cuboidal body comprising a convexly curved proximal body end portion and a generally complementary, concavely curved distal body end portion and two pairs of two opposed lateral surfaces extending from the proximal body end to the distal body end, the proximal body end and the distal body end having a distance from each other that is about equal to the distance between the two opposed lateral surfaces of each of the two pairs, the body comprising a suture channel horizontally extending through the proximal and distal body end portions and dividing the body into a first body portion and second body portion, the suture channel comprising proximal and distal suture channel openings; an actuator system comprising a suture engagement member, the engagement member being configured to selectively facilitate axial movement or release of one or more sutures through the channel in an open configuration, and to facilitate securement of the suture(s) in the channel in a locked configuration,wherein the actuator system comprises a spring-activated biasing system comprising a plunger slidably displaceable through a longitudinal channel extending between the proximal body portion and the distal body portion, the plunger having a bottom plunger portion arranged in the longitudinal channel and a top plunger portion extending partially outside the longitudinal channel, wherein the actuator system further comprises an abutment surface formed on the top plunger portion outside the body, and a compression spring extending between the body and the abutment surface, the compression spring having a first end and a second end, the first end abutting an outside surface of the body and the second end abutting the abutment surface,wherein the proximal body end portion comprises a face configured to contact a body surface, anchoring the body to the body surface when suture(s) are secured under tension by the engagement member in the locked position;wherein the proximal body end portion is free from structure protruding proximally therefrom, and the distal body end portion is free from structure protruding distally therefrom. 2. The device of claim 1, wherein the face has a length and a width between about 10 mm to 30 mm, and the proximal end portion is configured to contact a cutaneous surface. 3. The device of claim 1, wherein the actuator system is configured so that the open configuration constitutes an activated state and the locked configuration constitutes a non-activated state. 4. The device of claim 1, wherein the actuator system is configured so that the open configuration constitutes a non-activated state and the locked configuration constitutes an activated state. 5. The device of claim 1, wherein the spring biases the plunger to render the suture channel open or closed. 6. The device of claim 1, wherein the plunger comprises a substantially hollow rectangular structure and is connected to a button lever, wherein a plunger opening extends through two oppositely spaced vertical plunger faces, the plunger opening disposed between the top plunger portion and the bottom plunger portion, andwherein the biasing system is configured so that depression of the button lever causes the bottom plunger portion to become displaced into the longitudinal channel disposed in the second body portion, thereby aligning the plunger opening with the suture channel so as to create an open suture channel for passing one or more sutures therethrough. 7. The device of claim 1, wherein the top plunger portion includes locking teeth extending from opposite vertical plunger faces, each locking tooth comprising a locking tooth face engaged by a top surface of an open keyway extending from a body face in the locked configuration, wherein depression of the locking teeth into a hollow plunger area facilitates insertion or removal of the plunger through the longitudinal channel. 8. The device of claim 1, wherein the spring is a cylindrical coil spring surrounding the top plunger portion.
