Patent number: 5791088Abstract: A vehicle door assembly includes first and second weatherstripping components secured directly to the vertically movable window beneath the opening between the outer door panel and inner door trim panel such that the weatherstrips are not visible. The weatherstrips include upwardly protruding lip portions which cooperate with the base portion of the respective weatherstrip to form a channel for carrying water out of the door assembly. By securing the weatherstripping directly to the window, unsightly beltline weatherstrips are eliminated. Also, the frictional engagement of prior art beltline weatherstrips with the window is eliminated, thereby allowing downsizing of the window lifting mechanism, and allowing the use of plastic or glazed windows because the abrasion of prior art designs is eliminated.Type: GrantFiled: October 25, 1996Date of Patent: August 11, 1998Assignee: Ford Global Technologies, Inc.Inventors: Douglas Michael Martinelli, William Ernest Buehler, Darrell Kenneth Kleinke, Christian Michael Norton

Patent number: 5592939Abstract: A system for navigating a catheter probe through a body cavity includes a sensing coil affixed to a distal end of the probe. Magnetic fields are projected into the body cavity to induce voltage signals in the sensing coil that are sufficient to describe the orientation and position of the probe. A set of magnetic coils each generates a substantially uniform field in a single respective dimension. The orientation angles of the sensing coil may be determined from known values of the unidirectional fields and the measured induced voltage signals. Gradient magnetic fields with components in two dimensions are projected into the body cavity to induce another group of voltage signals. The geometrical intersection of constant voltage surfaces developed by certain gradient fields that produce the measured induced voltage signals is a set of lines on which the catheter is located. The point of intersection of such lines yields the positional coordinates.Type: GrantFiled: June 14, 1995Date of Patent: January 14, 1997Inventor: Michael A. Martinelli

Patent number: 5207672Abstract: An instrument for and method of effectively treating the prostatic urethra so as to relieve the symptoms associated with an enlarged urethra is disclosed. The tissue of at least selected portions of the prostate are compressed (preferably with a balloon inserted into the prostatic urethra so as to enhance hemostasis) and at least selected portions of the compressed tissue are directly irradiated (preferably with a laser beam transmitted from within the passageway in selected radial directions and moved along the prostatic urethra while exposing the tissue) so as to cause coagulation necrosis of selected portions of the compressed tissue so that as the tissue heals, the necrosed tissue slowly sloughs off during normal urination through the urinary tract so as to effectively remove the constricted portions of the prostatic urethra. Ultrasonic transducers are used from within the prostatic urethra to image the tissue as it is irradiated so as to monitor the procedure to insure proper exposure to the laser beam.Type: GrantFiled: January 14, 1991Date of Patent: May 4, 1993Assignee: Intra-Sonix, Inc.Inventors: Robert A.

Patent number: 4821731Abstract: An apparatus and method is disclosed for imaging internal features of a living body at a preselected site so that the data can be imaged in a quick, efficient and reliable manner with high resolution. The apparatus includes a catheter having a longitudinal axis, a proximal end and a distal end such that the catheter is adapted to be partially inserted into said living body so that said distal end is positioned relative to the preselected site and imaging data relating to the internal features can be acoustically provided at said distal end by moving said distal end through a plurality of positions relative to the site and generating an acoustic signal when the distal end is at each of said positions.
