Abstract: A multicomponent fluid separation and irradiation system is described containing a centrifuge drum and a source of radiant energy located within the drum. In a first embodiment a disposable rigid separation/irradiation chamber is provided with a cylindrical outer compartment located within the drum and opposing the radiant energy source. Whole blood is supplied to the chamber through a dynamic seal located at the center of the chamber. As the chamber is rotated, blood is separated so that energy from the source passes through the inner wall of the chamber and the separated plasma layer to irradiate the buffy coat layer. In a second embodiment, one or both of the walls of the outer compartment of the chamber are flexible so that the chamber will expand as blood is pumped in and will collapse as blood is pumped out.

Abstract: An insertion tool for an intraocular lens including a hollow barrel, a rigid annular tube extending from the distal end of the barrel, the stylet for reciprocating within the barrel and the rigid tube, an actuator extending through the side wall of the barrel and connected to the stylet to permit the user to move the stylet back and forth within the barrel. A paddle is attached to the distal end of the stylet. The intraocular lens is loaded into the paddle and then the paddle and the lens are retracted into the rigid tube for insertion into the eye through a small incision. The paddle unfolds the lens as it is retracted into the tube. When the distal end of the instrument is placed into the eye, the paddle and lens are ejected from the tube so that the lens may be deposited within the eye.

Abstract: An optic for an intraocular lens with finished, molded radii on the anterior and posterior edges of the peripheral surface of the optic. The optic has a thin central optical zone and a surrounding annular ring having sufficient material to support haptics. The ring is thicker than the optical zone and, thus, recesses the posterior surface of the optical zone to provide a capsulotomy space. The present novel optic is produced by novel molding pins which are shaped to provide the finished molded radii on the edges of the optic so that the optic requires little or no post-molding finishing or polishing other than the degating and deflashing.
