Publication number: 20240358489Abstract: As may be implemented in accordance with one or more embodiments characterized herein, aspects of the present disclosure are directed to an apparatus including first and second filters, a shaft and a frame coupled to the shaft and to the first filter. The frame and shaft operate to seal a perimeter of the first filter around an opening in a sidewall of a tubular structure, by pressing the frame against the perimeter and the sidewall. The second filter is also coupled to the frame and operates with the frame to extend into a cross section of the tubular structure away from the frame and the sidewall, with the frame sealing the first filter around the opening, and to filter particles from fluid flowing past the opening and along the length of the sidewall.Type: ApplicationFiled: July 8, 2024Publication date: October 31, 2024Inventors: Abdolrahim Zandi, J. Eric Goslau

Patent number: 11957562Abstract: Aspects of the present disclosure are directed toward catheter-based apparatuses, such as componentry utilized with or as part of catheters, or as catheters or catheter assemblies. As may be implemented in accordance with one or more embodiments, a method and/or apparatus involves a filter having a frame that forms a perimeter of the filter and separates opposing surfaces thereof. An articulated arm is connected to the frame and configured therewith to, when deployed within a tubular organ, engage with opposing inner sidewall portions of the tubular organ and to utilize the inner sidewall portions to seal filter to the inner sidewall by applying force to the frame.Type: GrantFiled: February 14, 2022Date of Patent: April 16, 2024Assignee: Transverse Medical, Inc.Inventors: Abdolrahim Zandi, J. Eric Goslau, Sepehr Fariabi

Publication number: 20240027417Abstract: A system for assessing biological tissue is disclosed. The system contains an illumination hardware arrangement comprising transmission and sensing hardware, the illumination hardware arrangement configured to inspect a biological tissue using at least two modes from a group containing: a three dimensional stereo imaging mode; a fluorescence imaging mode; a reflectance imaging mode; and a thermal imaging mode; and processing hardware configured to operate the illumination hardware arrangement according to a protocol comprising inspection settings of the at least two modes, wherein the processing hardware receives scan results for the at least two modes from the illumination hardware arrangement and identifies attributes of the biological tissue by constructing a three dimensional dataset from the scan results for the at least two modes and analyzing the three dimensional dataset.Type: ApplicationFiled: October 16, 2023Publication date: January 25, 2024Inventors: Fartash Vasefi, Kenneth Edward Barton, Nicholas Bennett MacKinnon, Abdolrahim Zandi, Kouhyar Tavakolian

Patent number: 10987118Abstract: As may be implemented with various aspects of the present disclosure, a mesh structure is coupled to inner and outer frames that operate with struts to apply pressure to the mesh. Such an approach may involve sealing the mesh around an opening, such as around one or more artery openings along an interior wall of vascular tissue (e.g., in an aortic arch). Accordingly, blood flow can be filtered in a manner that is useful for capturing particulates such as those resulting from surgical operations. In various implementations, the mesh, struts and frames are deployed using a catheter and shaft coupled to the frames. Such an approach can be implemented to apply a spring force from the shaft and through the frames for sealing the mesh.Type: GrantFiled: September 4, 2018Date of Patent: April 27, 2021Assignee: Transverse Medical Inc.Inventors: Abdolrahim Zandi, Sepehr Fariabi, J.
