Abstract
A ligation clip module of unitary construction adapted for use with a ligation clip applicator for housing and applying a ligation clip around a vessel. The ligation clip module comprises a module housing, ligation clip and pusher. The module housing forms a cavity having a first and second channels therein that house the ligation clip and pusher therein. The ligation clip includes a Y-shaped clip track having two extended arms and a U-shaped clip body with an extended slot for slidably engaging the clip track and closing the arms of the clip track about the vessel during application by the applicator. The module housing includes a frustoconical section with opposing tapered beveled portions that enhance visibility along the longitudinal axis of the module housing and a reduced diameter section that is adapted for attachment to the applicator. In operation, the module is attached to a distal neck portion of the applicator wherein an advancing element of the applicator forces the pusher inside the module housing forward through the two channels. The pusher then engages the proximal end of the clip body which slides over the clip track, thereby ligating the vessel between the two arm…
