초록 ▼

Novel apparatus and methods for a circumferential laser and methods for using a circumferential burning laser are disclosed. The circumferential burning laser comprises a conical surface at the distal end of a probe of the laser which is coated with a highly reflective material such as gold. The conical, reflective surface is designed so as to direct the laser light which is emitted through the interior metal lumen of the laser probe so that the laser light is redirected perpendicular to the longitudinal axis of the laser probe. This is in contradistinction to the typical laser probe wherein the laser light is directed longitudinally through the end of the laser probe. The laser light is provided by a carbon dioxide laser which is attached at the proximal end of the laser probe. The present invention also comprises methods for using a circumferential burning laser. The methods for using a circumferential burning laser involve placing the above-described laser probe in position relative to a target site. In the preferred embodiment, the laser probe is placed in the urethral canal such that a transurethral resection of benign prostatic hypertrophy may be performed.

대표청구항 ▼

A laser apparatus for placement into a body cavity and for redirecting laser light at a target site, the target site being comprised of body tissue or the like that is circumferentially located about the laser apparatus, the laser apparatus comprising: a probe means for insertion and placement comprising: lightguide means for guiding laser light along a pathway to a distal end of the lightguide means; tip means, joined to the lightguide means at the distal end thereof, for redirecting the laser light onto the target site but without focusing it such that the redirected laser light contacts the circumferentially located target site about substantially its entire periphery in a substantially continuous and uninterrupted annular pattern of substantially uniform power distribution; and placement means surrounding the probe means for supporting the probe means and for simultaneously isolating the target site from adjacent body tissue so as to protect the tissue from increased thermal conditions while laser light is directed through the laser probe, and wherein the placement means comprises window mean for allowing the redirected laser light to reach the target site through the placement means.
