Publication number: 20130216114Abstract: Systems and methods are provided for performing a minimally invasive procedure in an automated or semi-automated fashion, where an imaging probe having an imaging modality compatible with the presence of an intraluminal medium is employed to record images that are processed to identify regions of interest and direct a medium displacement operation during a subsequent minimally invasive operation that benefits from the displacement of the intraluminal medium. The minimally invasive operation may include recording images with a second imaging modality, or may be a therapeutic treatment. The method is may be performed in real-time, where images obtained from the first imaging modality are processed in real time to determine whether or not the minimally invasive operation is to be performed at a given position.Type: ApplicationFiled: November 8, 2011Publication date: August 22, 2013Applicant: COLIBRI TECHNOLOGIES INC.Inventors: Brian Courtney, Amandeep Thind

Patent number: 7972272Abstract: The present invention provides an imaging probe for imaging mammalian tissues and structures using high resolution imaging, including ultrasound and optical coherence tomography. The imaging probe uses electrostatic discharge for actuating a metalized cantilever which holds the end portion of imaging assembly which emits energy in the imaging probe device by holding the cantilever at a potential such that it is neither grounded or charged such that the only electrical path to ground is through a dissipative polymer forming part of the device which is enveloped by a wire or coil held at ground potential. A high voltage electrode attracts the metalized cantilever and the dissipative polymer is used to connect to the cantilever to ground causing the cantilever to move about thereby scanning the region in front of the probe.Type: GrantFiled: January 22, 2008Date of Patent: July 5, 2011Assignee: University Health NetworkInventors: Nigel Robert Munce, Victor Xiao Dong Yang, Brian Courtney, Amandeep Singh Thind

Publication number: 20060276743Abstract: The control of fluid introduction into and out of body conduits such as vessels, is of great concern in medicine. As the development of more particular treatments to vessels and organs continues it is apparent that controlled introduction and removal of fluids is necessary. Fluid delivery and removal from such sites, usually referred to as irrigation and aspiration, using fluid exchange devices that control also need to be considerate of potential volume and/or pressure in the vessel or organ are described together with catheter and lumen configurations to achieve the fluid exchange. The devices include several electrically or mechanically controlled embodiments and produce both controlled and localized flow with defined volume exchange ratios for fluid management. The applications in medicine include diagnostic, therapeutic, imaging, and uses for the introduction or removal of concentrations of emboli within body cavities.Type: ApplicationFiled: July 18, 2006Publication date: December 7, 2006Applicant: Kerberos Proximal Solutions, Inc.Inventors: JOHN MacMAHON, THOMAS GOFF, BRIAN COURTNEY
