Publication number: 20240115141Abstract: A method and apparatus of automatically locating in an image of a blood vessel the lumen boundary at a position in the vessel and from that measuring the diameter of the vessel. From the diameter of the vessel and estimated blood flow rate, a number of clinically significant physiological parameters are then determined and various user displays of interest generated. One use of these images and parameters is to aid the clinician in the placement of a stent. The system, in one embodiment, uses these measurements to allow the clinician to simulate the placement of a stent and to determine the effect of the placement. In addition, from these patient parameters various patient treatments are then performed.Type: ApplicationFiled: November 30, 2023Publication date: April 11, 2024Applicant: LightLab Imaging, Inc,Inventors: Joseph M. Schmitt, Joel M. Friedman, Christopher Petroff, Amr Elbasiony

Publication number: 20240099564Abstract: An imaging system for use in a patient is provided. The system includes an imaging probe, a rotation assembly, and a retraction assembly. The imaging probe collects image data from a patient site and includes an elongate shaft with a proximal end and a distal portion, with a lumen extending therebetween. A rotatable optical core is positioned within the elongate shaft lumen and an optical assembly is positioned in the elongate shaft distal portion. The optical assembly directs light to tissue at the patient site and collects reflected light from the tissue. The rotation assembly connects to the imaging probe and rotates the optical assembly. The retraction assembly connects to the imaging probe and retracts the optical assembly and the elongate shaft in unison.Type: ApplicationFiled: May 8, 2023Publication date: March 28, 2024Inventors: Christopher Petroff, Michael Atlas, Christopher Petersen, Christopher Battles, Jiyuan Yin, Nareak Douk, David W.

Patent number: 11923067Abstract: In part, the invention relates to a method for sizing a stent for placement in a vessel. In one embodiment, the method includes the steps of: dividing the vessel into a plurality of segments, each segment being defined as the space between branches of the vessel; selecting a starting point that appears to have substantially no disease; defining the diameter at this point to be the maximum diameter; calculating the maximal diameter of the next adjacent segment according to a power law; measuring the actual diameter of the next adjacent segment; selecting either the calculated maximum diameter or the measured maximum diameter depending upon which diameter is larger; using the selected maximum diameter to find the maximum diameter of this next segment; iteratively proceeding until the entire length of the vessel is examined; and selecting a stent in response to the diameters of the end proximal and distal segments.Type: GrantFiled: March 12, 2013Date of Patent: March 5, 2024Assignee: LightLab Imaging, Inc.Inventors: Joseph M. Schmitt, Hiram Bezerra, Christopher Petroff, Ajay Gopinath
