  • Patent number: 5672179
    Abstract: An intubation device and a method of intubating a patient with an endotracheal tube is disclosed. The device comprises a housing and a flexible, tubular sheath having one end connected to the housing and a free end extending away from it. The sheath, which is adapted to fit within the endotracheal tube, also has a special light at the end of the sheath's free end for selectively providing illumination. In use, the sheath is inserted into the endotracheal tube until the light is at the end of the distal end of the tube. A clamp on the intubation device then clamps the endotracheal tube to the housing to prevent relative movement between the tube and the sheath. A tube stop is then slid along the sheath into abutting contact with the proximal end of the endotracheal tube to identify the location on the sheath corresponding to the proximal end of the tube. When the tube is properly positioned in the patient, the light will create a distinct glow visible to an observer in the area of the sternal notch.

  • Patent number: 5507739
    Abstract: A dual wavelength laser is disclosed for use in dental therapeutic applications. The dual wavelength laser includes a laser cavity in which a laser crystal is disposed and preferably the laser crystal is an Nd:YAG laser, which, upon excitation, lases at two different wavelengths, each of which has a different gain. A shutter, or alternatively an optical filter, is selectively disposed within the optical path of the laser crystal whereupon the higher gain wavelength is selectively suppressed. Thus, with the shutter or optical filter removed from the optical path, the laser lases at its higher gain wavelength. Conversely, with the shutter or filter positioned within the optical path, the higher gain wavelength is effectively suppressed so that the laser crystal lases at the lower gain wavelength.

  • Patent number: 5383874
    Abstract: A catheter carries a functional component, like an ablating electrode, having a predetermined operating characteristic. The catheter also electronically retains an identification code that uniquely identifies the predetermined operating characteristic. The catheter is capable of transmitting the identification code to an external reader in response to a predetermined prompt. An associated apparatus, like an ablating energy source, reads the identification code and compares it to predetermined operating criteria. The apparatus will not permit interaction with the functional catheter component, if the identification code indicates that the functional characteristics of the catheter are not suited for the intended interaction. The catheter can also store usage information, to prevent reuse.

  • Patent number: 5348552
    Abstract: In a laser surgical unit having a contact laser probe (1), a hydroxyl group (13) is included in the contact laser probe so that a laser beam is partially absorbed by the hydroxyl group (13) to heat the contact laser probe (1) for transmission to living tissue. Consequently, a coagulation layer is formed in the living tissue along with vaporization and incision. At least a part of the contact laser probe (1) is made of a material which contains the hydroxyl group (13) generally in an amount of between 0.5 and 10 ppm. Alternatively, the hydroxyl group (13) may be included only in a portion adjacent to a surface of a tip portion of the probe (1). As a further alternative, a coating film containing the hydroxyl group (13) may be attached to the tip of the contact laser probe (1). The laser beam preferably has a wavelength between 1.5 and 15 .mu.m. For example, use is made of an Er:YAG laser beam, a Ho:YAG laser beam, or a CO.sub.2 laser beam.

The delivery system includes a handpiece adapted for rotatable coupling to a delivery arm coupled to the laser energy source such that the handpiece is rotatable about its longitudinal axis with respect to the delivery arm. A distal delivery system is coupled to the handpiece and delivers laser energy to the surgical site when the laser energy source is actuated. The handpiece includes a handpiece body adapted for rotatable coupling to the delivery arm and a handpiece head coupled to both the handpiece body and the distal delivery system. The handpiece head can be rotatably coupled to the handpiece body. In one embodiment, the handpiece head is angularly oriented at a fixed angle with respect to the handpiece body.

  • Patent number: 5344418
    Abstract: An improved optical system for treatment of disorders of the skin, especially vascular lesions, such as PortWine Stains. The system irradiates the skin with radiation at a predetermined wavelength and cools the skin during a predetermined time interval in coordination with delivery of the radiation. The absorption of the radiation by the skin and the change in temperature of the skin is monitored by the system and the operation of the radiation delivery system is controlled to optimize treatment of the vascular lesion. The source of irradiation is an arc lamp and the cooling system delivers a cooling gas to a lens in contact with the skin. The cooling gas can be carbon dioxide, freon, or any other appropriate gas. The lens used has a high heat conductivity and may be formed of sapphire.
