  • Publication number: 20110152715
    Abstract: A surgical cutting device comprises a cannula attached to an actuation mechanism that moves the cannula from a cocked position to a cutting position, a stylet including a distal portion having a sharp distal end, a sample collection region, a vacuum port, and a lumen extending from the vacuum port to the sample collection region such that the sample collection region is in fluid communication with the first vacuum port. When the cannula is in the cocked position, the sample collection region of the stylet is disposed distal of the cannula. The device also includes a fixed volume vacuum source. When cannula is in the cocked position, the vacuum port is not in fluid communication with the fixed volume vacuum source, and when said cannula is in the cutting position, the vacuum port is in fluid communication with the fixed volume vacuum source.

  • Patent number: 5310039
    Abstract: An apparatus for the fast and efficient transfer of integrated circuits between three locations: an input location, a test site location, and an output location. The apparatus includes a front and a rear work press assembly for transferring integrated circuits between the locations and for applying pressure during testing. The work press assemblies is constructed of a variable length shaft coupled to an arm extension which is coupled to a work press. The work press assemblies can each move between three horizontal positions, a first horizontal position associated with the input location, a second horizontal position associated with the test site location, and a third horizontal position associated with the output location. The work press assemblies move independently of one another.
