Abstract: An endoscopic insertion device for inserting an anastomosis ring having two unitary members in an anatomic tubular body member comprises an anastomosis ring adapter for mounting the unitary members in an engaging position, an inserter for inserting the ring adapter in the tubular body member, and an actuator for actuating the adapter to close the anastomosis ring. A method of using the endoscopic insertion device includes the steps of inserting the anastomosis ring in an engaged position into the tubular body member, securing opposite ends of the tubular body member to the engaged anastomosis ring, applying a biasing force to close the anastomosis ring, releasing the biasing force, and axially withdrawing the insertion device from the closed anastomosis ring.

Abstract: This application discloses a liquid reagent cuvette cartridge which is adapted for use with an analyzer apparatus. The disposable, substantially rigid cartridge includes a chamber and a plurality of cuvettes disposed adjacent the chamber. The cartridge has no secondary air escape means. An opening is located between the chamber and each cuvette. The cartridge is preferably filled by a series of pressurizing steps in which pressure is exerted on fluid in the chamber and fluid from the chamber is forced into the cuvettes. The air pressure in the cuvettes and chamber is then equalized, after which the chamber is again pressurized and fluid is again forced into the cuvettes. The filling operation is repeated until the cuvettes are uniformly filled to the desired level. The cuvette filling operation occurs in essentially a closed system so that the air in the cuvettes is not permitted to escape during a filling operation.
