Patent number: 9211657Abstract: A method for manufacturing an end effector assembly includes providing first and second jaw members moveable relative to one another about a pivot between a first, spaced-apart position and a second, approximated position. One of the first and second jaw members includes a cavity defined therein and the other of the first and second jaw members includes a stop member configured to be inserted into the cavity.

Patent number: 9150908Abstract: An automated method for detecting the presence of a nucleic acid in a sample, where the method is performed within a housing of a self-contained, stand-alone analyzer. The method includes purifying the nucleic acid after it has been immobilized on a magnetically-responsive solid support. A pipette of the analyzer is used to form a reaction mixture comprising the purified nucleic acid and all reagents required to perform a nucleic acid amplification. Amplification products are synthesized that include a nucleotide sequence contained in the nucleic acid or the complement of the nucleic acid. The amplification products are exposed to a probe in a mixture, where the probe forms a hybrid with one of the amplification products. The formation of the hybrid in the mixture provides an indication of the presence of the nucleic acid in the sample.Type: GrantFiled: May 21, 2014Date of Patent: October 6, 2015Assignee: GEN-PROBE INCORPORATEDInventors: Kelly G.
