Abstract

An electromagnetically induced cutting mechanism provides accurate cutting operations on soft tissues. The electromagnetically induced cutter is adapted to interact with atomized fluid particles. A tissue remover comprises an aspiration cannula housing a fluid and energy guide for conducting electromagnetically induced cutting forces to the site within a patient's body for aspiration of soft tissue. The cannula is provided with a cannula distal end. The proximal end of the cannula is provided with fluid flow connection to an aspiration source. Separated soft tissue and fluid are aspirated through the cannula distal end and the cannula by an aspiration source at the proximal end of the cannula.

PRIORITY INFORMATION

[0001] This application is a continuation-in-part of co-pending U.S. application Ser. No. 09 / 188,072 filed on Nov. 6, 1998 and entitled TISSUE REMOVER AND METHOD, which is commonly assigned and the contents of which are expressly incorporated herein by reference.

[0002] 1. Field of the Invention

[0003] The present invention relates generally to medical apparatus and, more particularly, to methods and apparatus for cutting and removing soft or hard tissue by aspiration.

[0004] 2. Description of Related Art

[0005] Turning to FIG. 1, a prior art optical cutter includes a fiber guide tube 5, a water line 7, an air line 9, and an air knife line 11 for supplying pressurized air. A cap 15 fits onto the hand-held apparatus 13 and is secured via threads 17. The fiber guide tube 5 abuts within a cylindrical metal piece 19. Another cylindrical metal piece 21 is a part of the cap 15. The pressurized air from the air knife line 11 surrounds and cools the laser as the laser bridge...
