1. An endoscopic device for deploying a hemoclip onto a desired target, the device comprising:
at least one hemoclip comprising a first jaw and a second jaw that intersect at a pivot joint to form an X-shape, the pivot joint including a joint with one axis of rotation;
a spring located behind the pivot joint and in between the first jaw and the second jaw, one end of the spring contacting the first jaw and another end of the spring contacting the second jaw such that the spring contacts both the first and second jaws; and
an endoscope comprising a channel sized for the at least one hemoclip and a distal portion having an opening connected to the channel where the at least one hemoclip is deployed,
wherein:
the at least one hemoclip is configured to be in an open position or in a closed position, and ends of the first jaw do not contact ends of the second jaw in the open position,
the at least one hemoclip is in a compressed X-shape when not deployed from the endoscope and is capable of being in an expanded X-shape when deployed from the endoscope; and
the at least one hemoclip has a proximal portion facing a target site and a distal portion facing inward towards the endoscope.
