Patent number: 11583338Abstract: 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.Type: GrantFiled: October 3, 2019Date of Patent: February 21, 2023Assignee: Visualase, Inc.Inventors: Ashok Gowda, Roger J. McNichols

Patent number: 10869721Abstract: In one embodiment, the disclosure is directed to an integrated apparatus for delivering energy to a tissue. The integrated apparatus included a housing having a distal end and a tubular structure located within the housing forming a first annulus between the tubular structure and the housing. The tubular structure is configured to accept an energy delivery component and is configured to form a second annulus between the tubular structure and the energy delivery component. The first annulus and the second annulus are configured to communicate with each other proximate to the distal end of the housing.Type: GrantFiled: May 16, 2016Date of Patent: December 22, 2020Assignee: Visualase, Inc.Inventors: Ashok Gowda, Roger J.

Patent number: 10219873Abstract: This invention is directed to devices and methods for stereotactic access, and particularly to a frameless stereotactic access device for accessing a body cavity and methods therefor. In general, a stereotactic device may include portions or features for fixing the device to a portion of a patient's body, such as, for example, a skull, such that the device may be generally spatially fixed in relation to the patient's body or part thereof. The stereotactic device may also generally include portions or features for guiding a medical device or other device at a particular trajectory in relation to the patient's body or part thereof.Type: GrantFiled: February 26, 2018Date of Patent: March 5, 2019Assignee: Visualase, Inc.Inventors: Ashok Gowda, Roger J. McNichols, Charles Houssiere, Manish Ahuja, Ravish Patwardhan
