Patent number: 11877889Abstract: Methods and apparatus are provided for electrically addressing multiple ultrasonic transducers that are connected to a common electrical channel and housed within an imaging probe. An imaging probe may comprise an imaging ultrasonic transducer and a moveable element for controlling the direction of an emitted imaging beam, and an angle sensing ultrasonic transducer, where the angle sensing ultrasonic transducer is configured for determining the direction of an ultrasonic imaging beam. The angle-sensing transducer may be configured to direct an angle sensing ultrasonic beam towards an acoustically reflective substrate and provide a signal by detecting a reflected ultrasonic beam reflected from the acoustically reflective substrate, where the acoustically reflective substrate is positioned relative to the movable element such that motion of the movable element produces a change in the signal.Type: GrantFiled: June 15, 2022Date of Patent: January 23, 2024Assignee: SUNNYBROOK HEALTH SCIENCES CENTREInventors: Brian Courtney, Amandeep Thind

Patent number: 10105918Abstract: Systems and methods are provided for forming an optical element within a transparent material using an irradiating optical beam, where the irradiating optical beam is employed to induce internal refractive index changes in the transparent substrate. Optical elements such as bulk and gradient index lenses may be formed in the transparent structure according various embodiments of the disclosure. An optical element may be formed by selecting a refractive index profile for the optical element, determining a corresponding suitable spatially dependent irradiation intensity profile for producing the selected refractive index profile, focusing an irradiating optical beam within the transparent structure, and controlling an intensity and position of the focused irradiating optical beam within the transparent structure according to the spatially dependent irradiation intensity profile.Type: GrantFiled: November 13, 2012Date of Patent: October 23, 2018Assignee: Conavi Medical Inc.Inventors: Amandeep Thind, Mark Harduar, Nigel Munce, Martin Jun

Patent number: 9907536Abstract: 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: GrantFiled: June 25, 2015Date of Patent: March 6, 2018Assignee: CONAVI MEDICAL INC.Inventors: Brian Courtney, Amandeep Thind

Patent number: 9839410Abstract: A catheter is provided that includes an external sheath, a rotatable conduit housed within the external sheath, and a fluid rotary joint having a rotatable insert that places an inner lumen of the rotatable conduit in fluid communication with an external port under rotation of the rotatable conduit. The rotatable insert may include a channel structure including an external annular channel. The rotatable conduit is received within the channel structure such that the inner lumen is in fluid communication with the external port through the annular channel under rotation. The external sheath may define an outer lumen that may be in fluid communication with the inner lumen at a location remote from a proximal portion of the catheter, and the outer lumen may be in fluid communication with a secondary port. The rotatable conduit may be housed within a torque cable that is connected to the rotatable insert.Type: GrantFiled: July 11, 2016Date of Patent: December 12, 2017Assignee: CONAVI MEDICAL INC.Inventors: Brian Courtney, Amandeep Thind, Isaac Jourard

Publication number: 20160045184Abstract: Systems and methods are provided for localizing and visualizing devices with the use of an intracorporeal ultrasound imaging probe during a medical procedure. A primary intracorporeal ultrasound imaging probe is employed to image a three-dimensional region via scanning, and to locate a secondary intracorporeal device having one or more ultrasonic beacon transducers. When an A-scan vector associated with the primary intracorporeal ultrasound imaging device is directed towards one or more of the ultrasound beacon transducers of the secondary intracorporeal device, a communication signal is transmitted from the secondary intracorporeal device to a control and processing system associated with the primary intracorporeal ultrasound imaging device, either through acoustic transmission or non-acoustic transmission. Example embodiments are provided in which acoustic communication may be employed within the imaging band, or in a separate communication band distinct from the communication band.Type: ApplicationFiled: March 14, 2014Publication date: February 18, 2016Inventors: Brian Courtney, Marc Lukacs, Amandeep Thind

Publication number: 20160022244Abstract: Medical probes having an inner fluidic path for flowing an internal liquid therein are disclosed, in which at least one internal surface in flow communication with the inner fluidic path is hydrophilic for the reduction of bubble adhesion thereto. In some embodiments, imaging probes are described, in which an internal surface in flow communication with an internal fluidic path, and through which imaging energy propagates, is coated with a hydrophilic layer that has a thickness and/or an acoustic impedance for reducing an impedance mismatch. Various configurations are described, including embodiments in which hydrophobic bubble trapping surface regions are included in addition to the hydrophilic surface regions. In some embodiments, a medical probe may have an inner lumen defined by an inner fluidic conduit, where at least a portion of the inner surface of the inner fluidic conduit is hydrophilic.Type: ApplicationFiled: March 14, 2014Publication date: January 28, 2016Inventors: Brian Courtney, Amandeep Thind, Alan Soong, Sneha Mathrani
