Disclosed herein are suture clip delivery devices that can be loaded with several flat, disk-shaped suture clips and can deploy the suture clips one after another onto respective sutures without reloading the device with additional suture clips. An exemplary device includes a handle portion with an actuation mechanism that is coupled to a shaft portion that holds and deploys the suture clips. The shaft portion includes a mandrel on which the suture clips are mounted and a retainer that restricts the suture clips from moving proximally when the actuation mechanism pulls the mandrel proximally, which causes a distal-most suture clip to slide off the mandrel and be deployed onto one or more suture. The mandrel and remaining suture clips can them move distally to prepare to deploy the next suture clip.

The device of claim 1, wherein the actuation mechanism causes the retainer to rotate relative to the mandrel and the suture clips, and wherein the rotation of the retainer causes cutting of the one or more sutures. 5. The device of claim 1, wherein the actuation mechanism causes the retainer to rotate relative to the mandrel and the suture clips, and wherein the rotation of the retainer allows the suture clips to move distally along with the mandrel relative to the handle portion. 6. The device of claim 1, wherein the suture clips each comprise at least one radially extending tab that projects into the axially extending slot in the retainer and is positioned in one of the circumferentially extending notches. 7. The device of claim 6, wherein the retainer has a first rotational position wherein the at least one tab of each suture clips is positioned in a respective one of the notches such that axial motion of the suture clips relative to the retainer is restricted, and wherein the retainer has a second rotational position wherein the at least one tab of each suture clip is not positioned in one of the notches and the suture clips are allowed to move axially relative to the retainer. 8. The device of claim 1, further comprising an electrical heating element positioned at a distal end of the mandrel, the heating element configured to cut a suture after a suture clip is deployed onto the suture. 9. A device for successively deploying a plurality of preloaded suture clips onto sutures, comprising: a proximal handle portion comprising an actuation mechanism;a mandrel having an inner lumen for receiving sutures, a proximal end portion coupled to the actuation mechanism, and a distal end portion having a distal opening in communication with the inner lumen, wherein the mandrel defines an axial dimension extending between the distal end portion and the proximal end portion, and a radial dimension perpendicular to the axial dimension, and wherein the mandrel is configured to receive at least one suture extending through the distal opening and into the inner lumen; anda plurality of annular suture clips mounted around the distal end portion of the mandrel, the annular suture clips being generally disk shaped and having a diameter oriented in the radial dimension and a thickness oriented in the axial dimension, wherein the thickness is smaller than the diameter;wherein the actuation mechanism causes the mandrel to move proximally relative to the suture clips, such that a distal-most one of the suture clips slides off of a distal end of the mandrel and onto one or more sutures extending into the distal opening of the mandrel; andwherein, after the distal-most one of the suture clips is deployed onto one or more sutures, the actuation mechanism causes the mandrel and a remaining portion of the suture clips to move distally relative to the handle portion such that a distal-most one of the remaining portion of the suture clips is ready to be successively deployed;the device further comprising a retainer positioned at least partially around the mandrel and coupled to the actuation mechanism independently of the mandrel, the retainer configured to restrict the suture clips from moving proximally relative to the handle portion when the mandrel moves proximally relative to the handle portion;wherein the actuation mechanism causes the retainer to rotate relative to the mandrel and the suture clips, and wherein the rotation of the retainer allows the suture clips to move distally along with the mandrel relative to the handle portion. 10.
