    摘要： A surgical device is provided for forming a channel through or partially through vascular tissue, including vascular tissue, utilizing both mechanical and laser energy, and, if desired, depositing a therapeutic agent therein. The device includes an optical fiber for transmission of laser energy, a housing, and a hollow guide attached to the housing through which the optical fiber extends. A needle is attached to the distal end of the optical fiber in fluid communication with a catheter surrounding the optical fiber. Additionally, an actuator is included operably connected to the optical fiber for selectively extending the needle and/or fiber from the hollow guide. Finally, a laser control device is contemplated operably connected to the optical fiber, transmitting laser energy from the distal end of the fiber after the needle has penetrated a layer of selected distance into the tissue.

    摘要： An optical fiber device for ablating a channel through a plaque deposit or a clot in a blood vessel is described. Laser energy is transmitted through one or a bundle of optical fibers to a quartz or fused silica cylinder, whose distal end surface has been made into a desired shape and sandblasted or carbon coated or both. The cylinder is received with a pocket defined in a sheath which surrounds the optical fibers. Moreover, the cylinder includes a circumferential recess and the sheath includes a circumferential rib which engages into the recess for securing the lens in the pocket. In one embodiment, the cylinder has a cavity formed therein and the distal end of the optical fiber extends into the cavity. In a further embodiment, the device is adapted to be guided along a wire extending through the pocket and an aperture defined in the sheath and/or a channel defined in the cylinder.

    摘要： A catheter device suitable for shrinking chordae tendineae of the human heart is provided having an energy conduit and a positioning device that facilitates the delivery of thermal energy, including coherent (laser) or non-coherent light, RF, microwave or ultrasound energy, to a predetermined region of the chordae tendineae or other collagen-containing tissue, such as the female urethra or the esophagus near the sphincter. The device comprises a tubular catheter containing an energy conduit, such as a fiber optic cable, adapted for delivering thermal energy to the tissue. The tubular catheter also contain a stabilizing device, disposed at its distal end, such as an asymmetrically shaped balloon or a retractable flexible metal hook. With the distal end of the catheter device positioned within a human heart, application of thermal energy to the chordae tendineae results in a shrinkage of the chordae, providing a treatment for primary mitral valve regurgitation.

    摘要： A lasing device for performing a myringotomy or like procedure is provided. The distal end portion of an optical fiber used to transmit a laser energy beam to the surgical site is covered with a disposable, removably mounted sheath, whose distal end is substantially transparent to the wavelength of laser energy being emitted through the optical fiber. Optionally, a relatively low power aiming beam can be emitted coaxially with the laser energy beam.

    摘要： The invention relates to a catheter device including an optical fiber whose distal end is disposed within a hollow tube with a sharp or needle shaped distal end, which can penetrate tissue. The distal end of the optical fiber and the hollow tube are configured so as to emit, by refraction (total internal reflection) or reflection from a metal surface, laser energy at an angle of about 80° to about 90° relative to the longitudinal axis of the optical fiber and hollow tube. The hollow tube is mounted to a housing and may be surrounded by a sheath.
