Patent number: 9675819Abstract: A system and method for providing real-time, image-guided high intensity focused ultrasound (HIFU) targeting and treatment of tissue. In one embodiment, the system includes an HIFU applicator and a user interface with a touchscreen display for three-dimensional visualization of the tissue. Image frames displayed on the user interface depict real-time images of the tissue, including an image parallel to a feature of the applicator and an image orthogonal to the parallel image. Reference lines may be sketched using the touchscreen and displayed on the image frames. In one embodiment, tissue boundaries are detected and marked on the image frames, either by the user or automatically by the system. In another embodiment, the user interface includes a footswitch for the user to interact with the system. In another embodiment, the system includes an ultrasound imaging component configured to undock from the system for use as a stand-alone ultrasound imaging device.Type: GrantFiled: July 16, 2013Date of Patent: June 13, 2017Assignee: Mirabilis Medica, Inc.Inventors: Lee David Dunbar, Jessica E. Parsons, Robert H. Pedersen, Tim Etchells, Gregory Paul Darlington, Michael P. H. Lau, Jens Ulrich Quistgaard

Patent number: 8337407Abstract: A two-stage control system is disclosed being made of a first control means for providing command and control of a robotic arm, and a second control means for the control and movement of a therapy device, such as an ultrasound transducer. The therapy device is positioned within a therapy head. The therapy head is attached to the distal end of the robotic arm. The two-stage control system provides for a macro and micro level of control for the therapy device during a therapy procedure.Type: GrantFiled: December 29, 2004Date of Patent: December 25, 2012Assignee: LipoSonix, Inc.Inventors: Jens U. Quistgaard, Tim Etchells, Gregory Paul Darlington, Charles S. Desilets

Patent number: 8052604Abstract: A combined imaging/HIFU probe includes an imaging scan head, a HIFU transducer, and an outlet port that delivers a flow of fluid across the HIFU transducer. At least a portion of the body cavity is filled with fluid in which the probe is immersed. The fluid provides a coupling for transmission of ultrasound energy between the probe and the patient. A flow of fluid may also be used to flush obstructions from an area of tissue near the HIFU transducer. Further described herein is a cuff to help retain fluid in the body cavity, a regulator to regulate fluid flow with respect to the body cavity according to a desired fluid pressure, and a cover for the HIFU transducer that has at least one perforation defined therethrough to allow fluid to flow through the cover. Further disclosed herein are methods of deploying a combined imaging/HIFU probe in a body cavity.Type: GrantFiled: July 31, 2007Date of Patent: November 8, 2011Assignee: Mirabilis Medica Inc.Inventors: Michael P. H. Lau, Gregory Paul Darlington, Michael J. Connolly, Zihong Guo

Publication number: 20110213280Abstract: A transducer seal designed to seal an open aperture of a transducer housing for a therapeutic ultrasound procedure. The seal has a membrane, a retainer and a mating device for locking in place with the transducer housing. The membrane is essentially transparent to ultrasound energy while being stretched taut about the retainer. The transducer seal may be made in a disposable or re-usable form.Type: ApplicationFiled: February 8, 2011Publication date: September 1, 2011Applicant: Medics Technologies CorporationInventors: Charles S. Desilets, George Barrett, Jens U. Quistgaard, Gregory Paul Darlington

Patent number: 7993289Abstract: Described is a system and method for the destruction of adipose tissue using an energy applicator such as a HIFU transducer. The system has a scan head containing an energy applicator, a mechanical arm for carrying the weight of the scan head, and a therapy controller such as a computer for controlling the operation of the scan head. The therapy controller may be part of a general purpose computer, and may be used as a robotic controller to automate the procedure. Methods are included for destroying adipose tissue in a quick, non-invasive manner.Type: GrantFiled: December 29, 2004Date of Patent: August 9, 2011Assignee: Medicis Technologies CorporationInventors: Jens U. Quistgaard, Tim Etchells, Gregory Paul Darlington, Charles S. Desilets

Publication number: 20110077559Abstract: A therapy head for use in HIFU procedures is described. The therapy head has an enclosure with a window, an energy applicator and a means of moving the energy applicator within the enclosure. The therapy head uses motors and actuators to move the energy applicator, usually an ultrasound transducer, inside the enclosure. A controller is provided either internally or externally that allows the therapy head to identify and distinguish locations where the therapy head should be to radiate energy into a patient. The controller uses the motors and actuators to move the energy applicator into the desired locations.Type: ApplicationFiled: December 6, 2010Publication date: March 31, 2011Applicant: Medicis Technologies CorporationInventors: Jens U. Quistgaard, Tim Etchells, Gregory Paul Darlington, Charles S. Desilets
