  • Publication number: 20240075569
    Abstract: A system and method for transferring a part being machined by a machine from a first fixture to a second fixture so that an un-machined side of the part can be exposed for machining, where the first fixture is secured to a first actuator and the second fixture is secured to a second actuator. The method includes securing the part to the first fixture, operating the first actuator so that the part is able to be machined on sides of the part except a side of the part coupled to the first fixture, and machining the part while the part is secured to the first fixture. The method operates the first actuator and the second actuator so that the part secured to the first fixture is aligned with the second fixture, and secures the part to the second fixture and releases the part from the first fixture.

  • Patent number: 6540768
    Abstract: A removable vascular filter system for blocking micro- and macro-emboli while allowing the continued perfusion of blood comprises a filter membrane positioned on a guidewire, wherein a free end of the membrane sits tightly against the guidewire when the filter membrane is in a collapsed state and wherein the filter has a means for deploying the filter membrane to assume a position substantially normal to the longitudinal axis of the guidewire. The filter membrane is comprised of a fine mesh material which has a pore size capable of blocking emboli while allowing continued blood flow, a preferred embodiment of which comprises regularly spaced, laser-formed holes, and in which the membrane has a scalloped proximal profile.
