  • Patent number: 6783491
    Abstract: Apparatus and methods are provided for placing and advancing a diagnostic or therapeutic instrument in a hollow body organ of a tortuous or unsupported anatomy, comprising a handle, an overtube, a distal region having an atraumatic tip. The overtube may be removable from the handle, and have a longitudinal axis disposed at an angle relative to the handle. The overtube may be selectively stiffened to reduce distension of the organ caused by advancement of the diagnostic or therapeutic instrument. The distal region permits passive steering of the overtube caused by deflection of the diagnostic or therapeutic instrument while the atraumatic tip prevents the wall of the organ from becoming caught or pinched during manipulation of the diagnostic or therapeutic instrument.

  • Patent number: 6750971
    Abstract: An instrument and related process for measuring color, shade, gloss, shape and/or translucence of a tooth. First, the instrument uses searchlight illumination to illuminate a tooth with constant irradiance. Second, the instrument uses colorimetric imaging to collect time-separated frames of different wavelengths of light reflected from a tooth and to combine those frames into a color image. Third, the instrument includes a sanitary shield to establish a reference color and a predetermined distance to a target tooth. Fourth, the instrument provides line-of-sight viewing so an operator may simultaneously view a display of the image on the instrument and the object being measured. Fifth, the instrument is impervious to pollutants because it incorporates a sealed measurement window. Sixth, optical measurements of a tooth taken by a dentist are compared to optical measurements of a prosthetic restoration for that tooth to confirm satisfactory matching of optical characteristics of the tooth and restoration.

  • Patent number: 6270494
    Abstract: A sheath for use on a closed loop Joule-Thomson cryosurgical probe, and the combination of the sheath and the closed loop probe. The sheath is slipped over the probe, thereby separating the probe from the environment. The sheath has a grip which fits over the handle of the cryosurgical probe, and an extendible shroud which can be longitudinally extended to cover tubing and which are attached to the handle. The sheath has a hollow multi-lumen catheter shaped and sized to fit snugly over the cannula of the cryosurgical probe. The catheter is not thermally conductive, preventing transfer of heat from the ambient to the gas mixture, and preventing the freezing of tissues at undesired locations along the catheter. A thermally conductive cap or tip is attached to the distal end of the hollow catheter. The thermally conductive cap or tip is biased against the cold tip on the probe by a biasing element in the sheath assembly, to promote heat transfer.

  • Patent number: 6196966
    Abstract: A method and apparatus are provided for imaging a narrow body lumen, the method comprising maintaining separation between a distal end of an optical viewing scope and a lumen wall with a spacing structure which extends distally from the distal end of an access catheter. Optional spacing structures include distal cages and a guidewire which is fixed to and extends distally from the access catheter body. The invention is beneficial during either retrograde imaging of the fallopian tube, and also allows antigrade imaging and advancing the access catheter and scope under the direction of the image provided, as it prevents the tubal wall from coming into such close proximity to a falloposcope as to produce “white-out” on the imaging monitor.

  • Patent number: 6022313
    Abstract: A minimally invasive technique for harvesting saphenous veins and the like for use as autografts in coronary artery bypass grafting surgery include a microsurgical instrument adapted to be demountably secured to the distal end of an endoscope. The instrument is inserted through an entry incision in the patient's skin, at the end of the endoscope which is used by a surgeon to advance the instrument along the saphenous vein, using the vein as a guide for the instrument. The instrument is tapered to provide initial separation of surrounding tissues from the vein, and cutting means supported by the instrument and viewed via the endoscope allow dissection of all tissues and side branch vessels from the saphenous vein. The instrument further provides a protective hood which prevents tissues or skin from blocking the endoscope. The desired length of saphenous vein is transected and is extracted via the entry incision. The technique minimizes trauma to the patient and to the saphenous vein graft.

  • Patent number: 5951464
    Abstract: A distal end part of an endoscope having a viewing window for introducing light from an object into an objective optical system for forming an observed image. An illuminating window is disposed in a side by a side relationship with the viewing window for illuminating a visual field of the objective optical system. A continuous transparent cover covers the surfaces of both the illuminating and viewing windows. A window glass is attached to the viewing window in such a manner that a virtual image of the outer edge portion of the window glass, which is produced by single reflection from the inner side of the outer surface of the transparent cover, lies outside the visual filed of the objective optical system.

  • Patent number: 5928140
    Abstract: The illuminated iris retractor probe system is a medical device for use in ophthalmic surgery, particularly anterior segment and posterior segment surgery where visualization of ocular structures is required. The device utilizes a handpiece to support a 23-gauge sheathed fiber optic element that transmits the illumination. The 23-gauge dimension of the sheathed fiber optic element allows it to be inserted through self-sealing incisions of 1.5-2.0 mm in size in the peripheral cornea, thereby allowing the incision to be self-sealing and thus avoiding the operative intervention and postoperative complications of sutures. The tip of the illuminated iris retractor probe has a backward bend or hook whose peripheral end is flush with the illumination end of a fiber optic element which is surrounded by a metal sheath. The specific angle of the hook and its location allows the probe to retract the iris during anterior segment procedures.
