Abstract
Some implementations provide an apparatus for percutaneous delivery of laser energy, the apparatus including two or more hollow spikes, each having an insertion end and a coupling end, each including an optical fiber embedded as a permanent fixture therein, each optical fiber capable of emitting laser from the insertion end of the corresponding hollow spike; and\a hub coupled to the two or more hollow spikes at the respective coupling ends of each hollow spike, the hub including a connector for coupling the apparatus to a laser generator.
Claims17
An apparatus for percutaneous delivery of laser energy, the apparatus comprising:
- two or more hollow spikes, each having a central cavity, an insertion end, and a coupling end, each including an optical fiber embedded as a permanent fixture in a respective central cavity, each optical fiber capable of emitting laser from the insertion end of the corresponding hollow spike;
- and
- a hub coupled to the two or more hollow spikes at the respective coupling ends of each hollow spike, the hub including a connector for coupling the apparatus to a laser generator,
- wherein the insertion end of each hollow spike comprises a cutting edge of a Quincke type spinal needle tip, the cutting edge including a beveled edge, and
- wherein each optical fiber is coaxial with an axis of the respective central cavity, and is positioned such that a distal end of the optical fiber is retracted within the respective central cavity corresponding to a plane that is inclined with respect to the axis of the respective central cavity, the plane defining a beginning end of the beveled edge and a distal end of the beveled edge.
A method of percutaneous application of laser energy for medical treatment, the method comprising:
- coupling a laser generator to a hub that is connected to two or more hollow spikes, wherein a connector included in the hub is configured to couple the laser generator to the hub, and wherein each hollow spike includes a central cavity, an insertion end, a coupling end that is connected to the hub, and an optical fiber that is embedded in a respective central cavity as a permanent fixture;
- percutaneously inserting the insertion ends of the two or more hollow spikes into a treatment area through a subject's skin, wherein the two or more hollow spikes are inserted at a same time;
- and
- delivering laser energy to the treatment area through the optical fibers housed within the two or more spikes,
- wherein the insertion end of each hollow spike comprises a cutting edge of a Quincke type spinal needle tip, the cutting edge including a beveled edge, and
- wherein each optical fiber is coaxial with an axis of the respective central cavity, and is positioned such that a distal end of the optical fiber is retracted within the respective central cavity corresponding to a plane that is inclined with respect to the axis of the respective central cavity, the plane defining a beginning end of the beveled edge and a distal end of the beveled edge.
