Publication number: 20240016551Abstract: Systems and methods for generating navigational guidance for a medical device within a body are disclosed. One computer-implemented method may include: receiving, at a computer server, image data associated with at least one anatomical object; determining, using a processor associated with the computer server and via application of a trained predictive navigational guidance model to the image data, navigational guidance for the medical device in relation to the at least one anatomical object; generating, based on the determining, at least one visual representation associated with the navigational guidance; and transmitting, to a user device in network communication with the computer server, instructions to display the at least one visual representation associated with the navigational guidance overtop of the image data on a display screen of the user device.Type: ApplicationFiled: July 10, 2023Publication date: January 18, 2024Applicant: Boston Scientific Scimed, Inc.Inventors: George DUVAL, James WELDON, Elizabeth ALBRECHT, Megan CHROBAK

Publication number: 20220218215Abstract: A system for measuring a pressure in a vein includes a needle sized and shaped to be inserted through a working channel of an endoscope. The needle is extending longitudinally and including a channel extending longitudinally therethrough. The system also includes a pressure sensing device including a longitudinally extending body sized and shaped to be slidably inserted through the channel of the needle and a sensor mounted on a distal portion of the body and connected to a proximal portion of the pressure sensing device via a connection cable. The sensor is configured to detect information corresponding to a pressure of a flow of blood through a vein.Type: ApplicationFiled: March 29, 2022Publication date: July 14, 2022Inventors: Douglas MELANSON, Peter L. DAYTON, Laura Elizabeth CHRISTAKIS, Sean P. FLEURY, Cory P. WRIGHT, George DUVAL, Vanessa MONAHAN

Publication number: 20210145267Abstract: A medical system may comprise an endoscope, including a handle and a sheath having a first illumination source, a second illumination source, and an imaging device at a distal tip of the sheath. The first illumination source may be configured to emit white light. The second illumination source may be configured to emit a non-white light. The system may also comprise a display device, a controller configured to interface with the endoscope and the display device, and a carrying case configured to contain the endoscope, the display device, and the controller.Type: ApplicationFiled: November 18, 2020Publication date: May 20, 2021Applicant: Boston Scientific Scimed, Inc.Inventor: George DUVAL

Patent number: 5649950Abstract: A system for percutaneous transluminal front-end delivery and retrieval of a collapsible prosthetic occluder includes a front-end loading portion, a control assembly and an introducer and retrieval sheath assembly. The front-end loading portion includes a tapering lumen portion and a smaller diameter distal lumen portion. An infusion port communicates with the distal lumen portion immediately adjacent the distal end of the tapering lumen portion. A valve assembly seals the front-end loading portion lumen proximally of the collapsed occluder. The distal end of the front-end loading portion lumen is inserted into the proximal end of an introducer and retrieval sheath assembly. A control assembly advances the occluder through the front-end loading portion, the introducer and retrieval sheath assembly and into the defect site. The retrieval sheath assembly is less flexible than the introducer sheath and is sufficiently rigid to evert the deployed occluder when retracted thereagainst.Type: GrantFiled: May 1, 1995Date of Patent: July 22, 1997Assignee: C. R. BardInventors: George Bourne, Randall W. Davis, George Duval, Dennis Goodine, James E. Lock, Gerry Ouellette, Stanton B. Perry, Maria Wagner, Gregory R. Whittaker

Patent number: 5626599Abstract: A method for percutaneous transluminal front-end delivery of a collapsible prosthetic occluder using a front-end loading portion, a control assembly and an introducer sheath. The prosthetic device is collapsed in a lumen of a front-end loading portion. A valve assembly seals the front-end loading portion lumen proximally of the collapsed occluder. Fluid is then infused through a port extending into the front-end loading portion in communication with the front-end loading portion lumen to remove air bubbles from the collapsed prosthetic device. The prosthetic device is advanced using a control assembly from the front-end loading portion into the introducer and ultimately into the defect site.Type: GrantFiled: May 1, 1995Date of Patent: May 6, 1997Assignee: C. R. BardInventors: George Bourne, Randall W. Davis, George Duval, Dennis Goodine, James E. Lock, Gerry Ouellette, Stanton B. Perry, Maria S. Wagner, Gregory R. Whittaker

Patent number: 5451235Abstract: An occlusion device for percutaneous transluminal correction of intracardiac and vascular septal defects is disclosed. The device comprises a pair of opposed occluders that are connected to one another using an interconnection that allows the occluders to move relative to one another. Additionally, a means for fluoroscopically visualizing and distinguishing the individual occluders of the device is also disclosed.Type: GrantFiled: April 14, 1994Date of Patent: September 19, 1995Assignee: C.R.

Patent number: 5425744Abstract: A device for the percutaneous transluminal repair of septal defects is disclosed. The device comprises first and second expandable occluders fastened to each other, each occluder including a framework having a central hub with elongated struts radiating therefrom. The struts are constructed such that they have a resistance to fatigue that exceeds the maximum fatigue stresses to which the struts will be subjected over a prolonged period in vivo. As such, the device exhibits a significantly decreased likelihood of metal fatigue failures after prolonged exposure in vivo.Type: GrantFiled: April 18, 1994Date of Patent: June 20, 1995Assignee: C.
