Patents by Inventor Klaus Baumeister

Klaus Baumeister has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7955324
    Abstract: A system for positioning the eye of a patient in alignment with a laser unit for laser surgery includes an alignment device that is mounted on the laser unit. It also includes a patient interface having a curved contact lens. Additionally, a clamp with an attached suction ring can be engaged with the interface to hold the lens against the eye of the patient. Thus, when the interface is joined with the alignment device, the lens is positioned against the eye of the patient at a predetermined distance from the laser unit for laser surgery.
    Type: Grant

  • Patent number: 7402159
    Abstract: A system for positioning the eye of a patient, relative to a stationary surgical laser unit, includes a chair for moving the patient. An eye stabilizing element is held against the eye, with a tapered receptacle extending outwardly therefrom. Also, an alignment device with a tapered tip is mounted on the surgical laser unit. In operation, the patient is moved to engage the receptacle of the eye stabilizing element with the tip of the alignment device, to thereby align the patient's eye with the surgical laser unit for laser surgery.

  • Publication number: 20060020259
    Abstract: A system for performing a corneal transplantation includes a laser source for generating a laser beam and a chair for positioning a patient relative to the laser source. A stabilizing element, engageable with the laser source, is fixated on the anterior surface of the patient's cornea to hold the cornea in alignment with the laser source. The laser source is then used to remove diseased tissue from the cornea of the patient, thereby creating a corneal cavity of known dimensions. In a subsequent step, a donor graft that was previously photoaltered to have substantially the same dimensions as the corneal cavity, is transplanted into the corneal cavity.

  • Patent number: 6730074
    Abstract: A system for accurately guiding a laser focal point along a predetermined path within the stroma of a cornea includes a contact lens for conforming the anterior surface of the cornea to a radius of curvature, Rlens, that is approximately 8.3 mm. Conforming the cornea to the lens causes minimal discomfort to the patient and does not upset the three-dimensional architecture of the corneal lamellae. As the focal point is advanced along a path within the cornea, the laser source is selectively translated parallel to the optical axis of the cornea to control the depth of the laser focal point. The movement includes three components: a first component, z1 that is dependent upon the shape of the contact lens, a second component, z2 that compensates for refraction at the surfaces of the contact lens, and a third component, z3, that compensates for refraction caused by the anatomical configuration of the cornea.
