  • Patent number: 5401270
    Abstract: Applicator device for laser radiation wherein the end of the radiation conducting light-wave conductor faces toward the object to be treated and is mounted in a tube-like sleeve which is closed and transparent at the end for the laser radiation. The end of the sleeve and/or the end of the light-wave conductor are provided with a scattering device which includes a scattering volume. For this purpose, the application of the scattering medium can be adapted to the particular requirement.

  • Patent number: 5364396
    Abstract: An implantable bone distraction device and method of using the device are disclosed. The device includes spaced first and second low profile blocks for subcutaneous implantation and attachment to osteotomically separated bone sections. The first block defines a drive chamber bore while the second block defines a threaded bore. A rotatable drive rod having a first end is received in the drive chamber bore of the first block. The rotatable drive rod's other end is threadably received in the threaded bore of the second block. The device further includes drive rod actuator located in the drive chamber bore for cooperating with the first end of the drive rod to rotate the drive rod so that one can adjust the depth to which the rod's threaded end is received in the threaded bore of the second block. This enables one to adjust the spacing between the first and second blocks, thereby enabling one to controllably distract the separated bone sections to enhance bone growth therebetween.

  • Patent number: 5275593
    Abstract: An ophthalmic surgery probe assembly includes a handpiece having a handpiece body and a hollow tip of a size suitable for insertion into a human eye, the hollow tip extending distally from the handpiece body. A laser connector is provided for connection to a laser source. A first optical fiber terminates at its proximal end in the laser connector and terminates at the distal end in the handpiece for transmitting laser light from the laser source to an eye to be treated, the first optical fiber extending at least partially through the handpiece tip. An illumination connector is provided for connection to an illumination source. A second optical fiber terminates at its proximal end in the illumination connector and terminates at the distal end in the handpiece for transmitting illumination from the illumination source to an eye to be treated, the second optical fiber extending at least partially through the handpiece tip.
