Methods and apparatus for performing interstitial laser therapy and interstitial brachytherapy
First Claim
1. A therapeutic energy application system comprising:
- a laser energy source;
an x-ray energy source;
an energy probe insertable into a tissue at a first position;
a stylet removably insertable into the energy probe, wherein the stylet is in the energy probe when the energy probe is inserted into the tissue, and wherein the stylet is configured to be removed from the energy probe after the energy probe is inserted into the tissue at the first position;
a laser optical fiber configured to be connectable to the laser energy source, the laser optical fiber removably insertable into the energy probe after the stylet is removed from the energy probe, and configured to emit laser energy to heat and ablate tissue;
an x-ray optical fiber configured to be connectable to the x-ray energy source, the x-ray optical fiber removably insertable into the energy probe after the stylet is removed from the energy probe and when the laser optical fiber is not in the energy probe;
a sensing probe separate from the energy probe, the sensing probe configured to be independently and separately inserted into the tissue at a second position spaced apart from the first position and configured to detect at least one temperature; and
at least one microprocessor configured to co-act with the laser energy source, the x-ray energy source, and the at least one sensing probe to;
send a signal to the laser energy source to change the amount of laser energy generated,receive a signal from the at least one sensing probe indicating a detected temperature, andsend a signal the x-ray energy source to change the amount of x-ray energy generated.

Abstract
A therapeutic energy system for performing interstitial laser therapy and brachytherapy includes two categories of components. The first category includes components usable to perform both interstitial laser therapy and brachytherapy. The second category of components includes components usable to perform either interstitial laser therapy or brachytherapy, but not both. The components co-act to apply therapeutic energy to tissue. The components of the first system include components inserted percutaneously into the tissue, such that interstitial laser therapy and brachytherapy can be performed sequentially without removing and re-inserting percutaneous components. Components of the second category include components not requiring additional puncturing of the skin of a patient, such that removing and inserting components of the second category from a patient is done easily and painlessly. An energy probe component does not maintain a cavity around the tumor mass. Surgical excision of tissue can be performed coincident to therapeutic energy treatment as disclosed.
