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.

Abstract: Insolubilized serum protein adsorbent, for example bovine serum albumin, of small particle size is an excellent adsorbent for adsorbable components in a biological fluid such as serum. Macroaggregated and polymerized albumin are particularly suited as adsorbents for unbound thyroid hormone in serum and can be used in diagnostic kits for determining total T.sub.4 and for T.sub.3 uptake.
