Abstract: A catheter for use in angioplasty and other medical procedures is disclosed. The catheter features a flexible-wire mesh tip movably attached at a distal end of the catheter, the tip being expandable from a contracted position which it is first in when the catheter is deployed inside the lumen of a vessel, to stretch open the lumen and eliminate a flow obstruction therein, such as is caused by plaque deposits; the tip subsequently being returnable to its contracted position inside the catheter when the catheter is withdrawn from the lumen of the vessel. Radio frequency energy may additionally be used to weld the source of the flow obstruction to the wall of the lumen leaving a conduit of sufficiently expanded diameter to allow resumption of normal flow in the vessel.

Abstract: In an external-cavity tunable wavelength light source using a semiconductor laser (LD) (1), when an interferometer serving as an optical filter is constituted by part of an external cavity, an external-cavity longitudinal mode can be selected with good reproducibility, and a side mode suppression ratio can be increased. A light beam emitted from an AR-coated facet of an LD (1) is converted into a collimated beam by a lens (2), and the collimated beam is incident on a Mach-Zehnder (MZ) interferometer (5) serving as an optical filter. An interference light beam emerges from the MZ interferometer (5) toward a diffraction grating (3) serving as a preselector. Only a light component having a specific wavelength and selected by spectrally dispersing the interference light beam reversely travels in the same optical path as that of the interference light beam and is returned to the LD (1). In this manner, a cavity is formed between the LD (1) and the diffraction grating (3), and a laser beam having a wavelength determined by three relationships between an external-cavity longitudinal mode, a cavity loss caused by the diffraction grating (3), and the output characteristics of an interference light beam from the MZ interferometer (5) is oscillated.
