  • Patent number: 10433909
    Abstract: The present invention is directed to systems and methods for thermal therapy, especially to detection-guided, -controlled, and temperature-modulated interstitial thermal therapy. Thermal therapy may be used to treat the tissues of a patient. In the case of interstitial thermal therapy, energy is applied to generate heating of the tissue to affect treatment, such as, for example, thermally inducing tissue damage (e.g. thermally-induced tissue necrosis), which may be useful in treating tumors and/or other diseased tissues. Since targets for thermal therapy are internal to the patient, the use of detection guidance may be useful in locating and monitoring treatment of a target tissue.

  • Patent number: 10314992
    Abstract: The volume of a hyperinflated lung compartment is reduced by sealing a distal end of the catheter in an airway feeding the lung compartment. Air passes out of the lung compartment through a passage in the catheter while the patient exhales. A one-way flow element associated with the catheter prevents air from re-entering the lung compartment as the patient inhales. Over time, the pressure of regions surrounding the lung compartment cause it to collapse as the volume of air diminishes. Residual volume reduction effectively results in functional lung volume expansion. Optionally, the lung compartment may be sealed in order to permanently prevent air from re-entering the lung compartment. The invention further discloses a catheter with a transparent occlusion element at its tip that enables examination of the lung passageway through a viewing scope.

    Abstract: Systems for visualizing cardiac tissue during an ablation procedure are provided. In general, the systems include an imaging module configured to measure absorbance data at first and second wavelengths wherein the ratio of these absorbance values identifies the nature of the tissue (e.g., lesion, de novo tissue, etc.). The imaging module can also include a video system having at least two chips with corresponding bandpass filters centered at the first and second target wavelengths. The system can also include a processor and/or video monitor for combining the images produced by the various chips, determining treated and non-treated tissue based on the ratio of absorbance values at the target wavelengths, and displaying images of the treatment area. Methods of visualizing cardiac treatment areas during ablation procedures are also provided herein.

  • Patent number: 9014788
    Abstract: An optical coherence tomography probe and laser combination device configured for real-time z-directional guidance of the incisional depth of a surgical procedure. It can be used alone or placed within the working channel of an endoscope. The device includes an OCT single mode fiber, and a laser fiber or laser hollow waveguide or electrical surgical wire positioned adjacent to the OCT single mode fiber. The single mode fiber is configured to move laterally when activated by an actuator to scan light data reflected from a sample that is positioned in front of a distal end of the device. The light data can be processed to generate a B-scan image. The device can collect data in real-time during lasing, or immediately prior to and following the cutting. The surgical tool, when coupled to a processor, can deactivate when the B-scan image identifies that the incision is within a predefined tolerance.

  • Publication number: 20150005577
    Abstract: A noninvasive treatment of uterine growths such as myomas (fibroids) and polyps is presented. Treatment involves carrying out diagnostic hysteroscopy and ultrasound procedures to detect, measure, and evaluate unwanted uterine growths; then inserting optical fiber into a hysteroscope, reaching target tissue with optical fiber and eliminating said tissue or shrinking it to a size/shape for easy mechanical removal. Finally, ultrasound imaging is used to confirm success of procedure. In one embodiment, optical fiber has an off-axis firing end but can be inserted inside a conventional hysteroscopy device. In another embodiment, a laser interstitial thermal therapy (LITT) fiber is used to treat myomas found on the outside of the uterus. A high energy laser is used that can emit at wavelengths easily absorbed by water and blood, such as 980 nm and 1470 nm. Procedure is fast and can be done in the physician's office with little or no anesthesia used.
