  • Patent number: 11664585
    Abstract: An on-body antenna is provided that overcomes mismatch loss problems associated with current on-body antennas and is capable of operating over a wide range of frequencies with low transmission loss. At least a first antenna element of the on-body antenna is configured to receive an oscillating electric current and to radiate an oscillating electromagnetic field over a predetermined range of frequencies. The first antenna element is made of non-electrically-conductive material having a first relative permittivity. At least a second material having a second relative permittivity can be disposed on or in the first antenna element. Disposing the second material provides the first antenna element with an effective permittivity that can be closely matched to a frequency-dependent permittivity of biological tissue of a subject. The first non-electrically-conductive material and the second material can be preselected to have relative permittivities that allow anisotropy to be achieved.

    Abstract: The invention comprises novel microwave antennas wherein the microwave field profile generated by an antenna is tailored and optimized for a particular clinical application. The antennas disclosed herein incorporate one or more additional elements called shaping elements that use unique properties of microwaves such as interaction of a microwave field with one or more conductive or non-conductive elements to shape or redistribute the microwave field. Such shaping elements may be used to reduce the undesired backward coupling of the emitted microwave field to the transmission line. Such shaping elements may be used to increase the power efficiency of the antenna. The invention also discloses devices and methods for treating tissue with microwave energy emitted from the antennas for use in applications such as destroying a soft tissue by microwave ablation.

  • Patent number: 11185234
    Abstract: Resonance Raman scatter is used to differentiate in quasi-real time (QRT) anomalous tissue from adjacent normal tissue. The fingerprint generated from the tissue by a 1 second pulse of 532 nm emission for approximately one second is collected and is relayed by fiber-optic to a computerized controller that determines whether the target tissue is anomalous or normal. If anomalous it is ablated. This is performed by a pattern of Resonance Raman diagnostic emission and diagnostic sensor fibers. This diagnostic/therapeutic pattern of fibers can be moved by a joystick or robotically controlled. The data received by the computer is examined instantly, and should the site be diagnosed as anomalous, the optical biopsy/ablation is repeated immediately and repeated until the site is read as normal. Novel arrays of the diagnostic and therapeutic energies ensure a 3D anomalous tissue free zone around the removal site.

  • Patent number: 11129673
    Abstract: A vapor-based ablation method mitigates constriction of the airways for the treatment of asthma and COPD. A vapor ablation catheter is advanced along the airways, through the airway wall, and to an extra-airway target tissue. The position of the catheter is assessed to determine whether the catheter is in contact with the target tissue. In embodiments, the distal energy delivery section of the catheter is manipulated to contact an exterior surface of the target tissue, or to enter the target tissue. Once the position is confirmed, vapor is delivered to the target tissue through an egress port with a sufficient amount of energy to ablate the target tissue. The target tissue may vary and include smooth muscle surrounding the airways, and nerves that control the smooth muscle. Methods for treating lung cancer are also described including delivering a vapor at lung tumors and growths, and blood vessels feeding the lung tumors and growths.
