Blood separation chamber with constricted interior channel and recessed passage
First Claim
1. A blood separation chamber for rotation about an axis comprisinga low-G wall and a high-G wall extending circumferentially about the axis in a spaced apart relationship to define between them a separation channel, a partial interior wall extending partially into the separation channel from the low-G wall toward the high-G wall, to thereby define a constricted channel along the high-G wall, the constricted channel including a recess extending into the high-G wall, a first passage communicating with the separation channel on one side of the recess, and a second passage communicating with the separation channel on the other side of the recess, and a full interior wall extending across the separation channel to define a terminus in the separation channel circumferentially spaced from the partial interior wall.

Abstract
A blood separation chamber for rotation about an axis includes an interior channel, which includes a recess that extends outside the bounds of the walls establishing separation zone. The recessed interior channel permits the yields of individual blood components separated in the chamber to be. maximized without cross-contamination or contamination by other components present in the chamber.
