Patent Images
1. A percutaneously-insertable apparatus for guiding laser light percutaneously in a body, comprising:
- an elongated tube having an exterior end which remains outside the body and having an interior end which extends into a solid mass of the body;
an optical guiding means for guiding a laser beam, said optical guiding means being disposed along said elongated tube, said laser beam emitted from said optical guiding means being nonaligned with at least a first portion of said elongated tube and being percutaneously guidable in the solid mass from said exterior end of said elongated tube;
position indicator means for preventing said optical guiding means from being inserted beyond a preset distance in the body; and
engagement means for providing that said elongated tube and said optical guiding means are rotatable together while inserted percutaneously in said solid mass, said engagement means including a housing and a deformable member disposed in said housing that grips said optical guiding means when said housing is rotated.

Abstract
An elongated tube for inserting instrumentation during a percutaneous diskectomy using a laser introduces an optical guide into the nucleus of a herniated disc. The optical guide is disposed along the elongated tube and guides a laser beam. The laser beam which is guided by the optical guide is not aligned with at least a portion of the elongated tube.

5. A percutaneously-insertable apparatus for guiding laser light percutaneously in a body, comprising:
-
an elongated tube for receiving an optical guiding means for guiding a laser beam therewithin, said elongated tube having an exterior end which remains outside the body and having an interior end which extends into a solid mass of the body, said elongated tube being configured so that said laser beam emitted from said optical guiding means is nonaligned with at least a first portion of said elongated tube and is percutaneously guidable in said solid mass from said exterior end of said elongated tube; position indicator means for preventing said optical guiding means from being inserted beyond a preset distance in the body; and engagement means for providing that said apparatus and said optical guiding means are rotatable together while inserted percutaneously in said solid mass, said engagement means including a housing and a deformable member disposed in said housing that grips said optical guiding means when said housing is rotated.
