  • Publication number: 20070100229
    Abstract: An apparatus and method for determining a volume of tumor mass destroyed. The present invention includes a temperature probe and a laser probe having a temperature sensor. The laser probe and temperature probe are inserted to measure a temperature of the tumor mass and a temperature of tissue mass surrounding the tumor mass. By determining the volume of tumor mass destroyed, a graphical representation of the volume of tumor mass destroyed is provided whereby real-time visual monitoring of the destruction of the tumor mass is achieved.

  • Publication number: 20060241727
    Abstract: Apparatus and method for performing interstitial laser therapy and adjunctive therapy on a patient are revealed. The apparatus employs a combination of a mammography unit, an interstitial laser treatment device attached to the mammography unit and a treatment platform positioned relative to the mammography unit to enable the interstitial laser therapy to be performed. The use of the treatment platform with the mammography unit enables the interstitial laser therapy to be performed and, if necessary, adjunctive therapy to be performed in the same treatment room without transferring the patient to a new platform.

  • Patent number: 5853366
    Abstract: A marker element is made of radiopaque material and includes at least two leg portions of approximately equal length connected at an angle relative to each other to form a generally V-shaped resilient member that is capable of being positioned wholly within the body of a patient. A localizing device and method using the marker element for marking a tissue mass of interest are also provided. The device and method include an elongate guide member, such as a cannula, having a first end that is inserted into the body so as to be directed toward a position proximate the tissue mass of interest and an opposite second end that extends from the body. A guide path extends between the first end and the second end of the guide member. The marker element is introduced into the second end of the guide member using a marker element dispenser and then urged along the guide path using a stylet or similar prodding member.

  • Patent number: 5569240
    Abstract: Apparatus and method for locally generating hyperthermia-induced coagulation necrosis in tissue masses located deeply within the body of a subject. High energy laser radiation is introduced into the target tissue mass using an optical fiber inserted into a metallic cannula through which a suitable fluid is coaxially flowed. A combination of the fluid flow and the slow withdrawal of the cannula/fiber combination during therapy protects the optical fiber tip, thereby preserving its energy transmission characteristics. After establishment of a small fluid bolus in front of the fiber tip, fluid flow which is approximately proportionate to the laser energy employed has been found to be most effective in this regard.
