Patent Images
1. A laser soft tissue aspiration device comprising:
- an aspiration cannula having a proximal end and a distal end, the aspiration cannula having a lumen provided with fluid flow connection to an aspirated soft tissue outlet port at the proximal end;
at least one aspiration inlet port adjacent to the aspiration cannula distal end and in fluid flow connection to the lumen;
a laser guide tube extending longitudinally along the exterior of the aspiration cannula, said laser guide tube extending from the aspiration cannula proximal end and terminating at a laser guide tube termination point near the at least one aspiration inlet port; and
a laser energy transmission guide extending longitudinally within said laser guide tube and external to the aspiration cannula, said laser energy transmission guide extending from a laser energy source at the aspiration cannula proximal end to a point near the laser guide tube termination point, the laser energy transmission guide being configured to direct laser energy substantially across the aspiration inlet port.

Abstract
This invention relates to a device and method for improving the surgical procedure of soft tissue removal by aspiration and more particularly to a device and method utilizing laser energy directed substantially across the inlet port to more readily and safely facilitate the separating of soft tissue from a patient in vivo. This invention has immediate and direct application to the surgical procedure of liposuction or body contouring as well as application in the surgical procedures of other soft tissue removal such as brain tissue, eye tissue, and other soft tissue inaccessible to other soft tissue aspiration techniques.

26. An in vivo surgical method of aspirating soft tissue from a patient comprising:
-
inserting an aspiration cannula through the patient'"'"'s epidermis, so that a distal end of the aspiration cannula is positioned in an area of soft tissue, said aspiration cannula provided with a lumen in fluid flow communication with at least one aspiration inlet port adjacent the aspiration cannula distal end; providing laser energy from a laser energy source to a laser energy transmission guide extending longitudinally within a laser guide tube, said laser guide tube extending longitudinally along the exterior of the aspiration cannula, the laser energy transmission guide transmitting the laser energy to a point near the at least one aspiration inlet port and being configured to direct laser energy substantially across the aspiration inlet port to perform localized soft tissue cutting and blood vessel coagulation; providing an aspiration source at a proximal end of said aspiration cannula to aspirate soft tissue through said aspiration inlet port and said aspiration cannula; activating the aspiration source; and activating the laser energy source. - View Dependent Claims (27, 28)
