摘要： A method and system are described for performing photorefractive keratectomy, a desired refractive correction in the corneal tissue. The method and system employ control (32) of the effect of ocular fluid at the corneal surface so as to reduce the disturbance of such fluid on the desired ablation process while maintaining hydration of the corneal tissue. Controlling the average repetition rate (26) of the radiation pulses (24) applied to the corneal surface so as to reduce intrapulse fluid accumulation at the corneal surface without dehydrating the corneal tissue, selecting an increased fluence level of the pulse applied to the corneal surface to reduce the effect of fluid accumulation at the corneal surface, and applying evaporative energy to the site of incidence of a pulse of an ablative beam prior to incidence of said pulse at said site are shown as ways to effect this control. Application of the new method and system to wide area ablation techniques and to scanning techniques are described.

摘要： System for internally treating a body by thermal means using microwave energy. The system comprises a generator (1) of microwave energy at a frequency fO, at least one path (20, 21) for the transmission of microwave energy, each path generating a modulated microwave treatment signal, the microwave energy carrier wave of two successive paths having a phase shift of predefined value. At least one microwave applicator (30, 31) is associated with one of the paths to enable the microwave energy supplied by said path to be applied to distinct points adjacent to the area (Z) to be treated, and a radiometer (4) with two temperature references is selectively interconnected to the applicator (30, 31), which then acts as the temperature sensor, the absolute temperature of the point adjacent to area Z to be treated being thereby determined. The radiated microwave energies and the instantaneous temperatures of the distinct points of area Z to be treated are displayed (7). Application in hyperthermic treatments, especially of living tissues.

摘要： An instrument for and method of effectively dilating a stenotic region of a passageway of a portion of the living body, preferably the prostatic urethra, so as to relieve the symptoms associated with the stenosis. In the preferred system the tissue of at least selected portions of the prostate (172) are compressed (preferably with a balloon (8) inserted into the prostatic urethra so as to enhance hemostasis), and at least selected portions of the compressed tissue are denatured (preferably with a laser beam transmitted from within the passageway in selected radial directions) so that as the denatured tissue heals, the denatured tissue tends to shrink so as to effectively dilate the portions of the prostatic urethra. Ultrasonic transducers are used from within the prostatic urethra to image the tissue as it is denatured so as to monitor the procedure to insure proper exposure to the laser beam.

摘要： The skin surface of a patient may be irradiated with the microwaves of a frequency of 250 to 353 MHz (i.e., a wavelength of about 85 to 120cm.). A conductive metal housing (10) having an open bottom and closed walls on all other sides overlies the skin surface. The interior of the housing carries a pair of opposed slabs (14) of material having a dielectric constant of more than (4) and defining a space therebetween. The microwaves are radiated from a microwave antenna (18) projecting into said space (16) through a wall in the housing, with the antenna being generally parallel to the open bottom. The slabs are of sufficient thickness to provide generally uniform electric and magnetic field intensities throughout the space. During operation, air is blown into the space through an aperture (24) in a wall of the housing to cool the skin with the air passing out of the open bottom.

摘要： System (10) for irradiating living bodies or portions thereof, using electromagnetic radiation. A source or generator (18) provides electromagnetic energy at a selected frequency within an operational band width, via a coaxial cable (22) to an applicator (20) for radiation into living tissue (12). The source (18), cable (22), and applicator (20) each have a characteristic impedance approximately equal to the average impedance of the living tissue (12) over a broad frequency band, thus enabling efficient operation of the apparatus (10) without using auxiliary impedance matching devices. The applicator (20) is of a waveguide transmission line type (96) enabling efficient transmission and radiation of the electromagnetic energy and further incorporates means (58) for cooling surface portions (24) of the living tissue (12) during radiation thereof. Selective dielectric loading (114, 116, 118, 120 + 122) is provided. A feedback control system (28) including temperature sensors (34, 36 + 38) placed onto or into the tissue (12) enables the control of tissue surface and subsurface temperatures within a preselected range by adjusting the power level of the generator (18).

摘要： This invention is a non-contact apparatus and method for performing laser thermal keratoplasty capable of scanning of treatment areas with shapes that reduce regression. The apparatus includes laser sources (70, 78, 40), a projection optical system, observation system, and control system. The projection system uses two steering mirrors (56, 58) to control laser beam position on the cornea. This projection system enables precise control of the area of corneal heat shrinkage using relatively low-powered lasers, such as diode lasers. Desired changes in corneal refractive power are produced by selected patterns of photothermal shrinkage of corneal collagen tissue. The selected patterns are arrangements of oblong shapes that are preferably tapered at the ends of the long axis. The oblong shape and tapering distribute tension in the cornea over a wider area of collagen shrinkage and improve the stability of refractive correction. The long axes of the oblong treatment areas are preferably oriented radially for hyperopia correction and circumferentially for astigmatism correction.

摘要： A catheter shaft (32) carries a coaxial cable (76), the terminal end of which contains a dipole antenna (74) with opposing first and second helical elements (142, 144). The first and second helical elements (142, 144) originate from a common connection to an outer conductor (124) of the coaxial cable (76). The first and second helical elements (142, 144) are formed by winding flat wire (140) around an outer insulator (126) of the coaxial cable (76) near a terminal end of the coaxial cable (76). A variable, controllable impedance (128, 202) is connected between an inner conductor (120) of the coaxial cable (76) and a point on the second helical element (144) where the resistive component of the antenna's impedance matches the characteristic impedance of the coaxial cable (76). The impedance match minimizes reflective losses of the antenna (74), thereby maximizing power transferred to the antenna (74). The antenna (74) has an effective electrical length which is equal to one-half the wavelength of the radiation emitted, independent of the physical length of the antenna. The antenna (74) also has a radiation length which can be adjusted by varying the number in pitch and turns of the flat wire (140) and the location of the impedance matching point.
