Patent number: 12364491Abstract: An actuated telescoping system for navigation within a vascular lumen and thrombectomy of a thrombus. The system includes a tubular catheter member having an open distal end defining a catheter lumen, a vacuum source, a rotational drive system, a flexible shaft having a channel coupled to the rotational drive system for rotational movement in response thereto, and an optional guidewire selectively inserted at least partially within the flexible shaft. The flexible shaft is at least partially disposed within the tubular catheter member configured for uncoupled rotational and translational motion therein and to optionally define a corkscrew motion in response to rotational driving force by the drive system that results in formation of hydrodynamic vortices within the catheter lumen.Type: GrantFiled: February 12, 2024Date of Patent: July 22, 2025Assignee: The Regents of The University of MichiganInventors: Luis Emilio Savastano, Jeffrey Stephen Plott, Yang Liu, Yihao Zheng, Albert Jau-Min Shih

Publication number: 20250176972Abstract: A portable compact hemorrhage occlusion includes a base and a pressure plate removably attached to the base. A strap carriage operably attached to the base and is linearly translatable relative to the base. A translation assembly is operably connected to the base and to the strap carriage. A strap is operably and directly connected to the strap carriage without being directly connected to the base. The translation assembly moves the strap carriage away from the base when the translation assembly is operated in a first direction and towards the base when the translation assembly is operated in a second direction.Type: ApplicationFiled: November 27, 2024Publication date: June 5, 2025Inventors: Kevin R.

Publication number: 20240382667Abstract: A device for wound irrigation and debridement includes a body extending along a longitudinal axis. The body comprises an interior region and an opening such that that the interior region and the first opening are configured to transfer an irrigation fluid. The body comprises a compliant region having a first stiffness and a debridement region having a different second stiffness. The compliant region defines a distal surface. In a first configuration, the compliant region defines a first axial dimension, the distal surface engages a target body region, and the debridement region is axially offset from the distal surface and disengaged from the target body region. In a second configuration, the compliant region is compressed to define a second axial dimension less than the first axial dimension, thereby engaging the debridement region with the target body region, and the distal surface engages the target body region.Type: ApplicationFiled: July 29, 2024Publication date: November 21, 2024Applicant: The Regents of The University of MichiganInventors: Paul Stephen CEDERNA, Nishant GANESH KUMAR, Jeffrey Stephen PLOTT

Patent number: 12101395Abstract: Cryptographic techniques are provided for generating, distributing, validation, and processing secure commands on different devices and/or peripherals. A control device generates and encrypts a key corresponding to a secure command using a private key of control device to produce a key envelope. Control device further encrypts the key envelope with a recipient's public key producing a recipient envelope. The recipient envelope is delivered to a recipient's device. The recipient's device decrypts the recipient envelope with a private key of the recipient's device producing the key envelope. The key envelope is delivered back to the control device. The control device decrypts the key envelope producing the key, validates the key, and processes a secure command on behalf of a secure resource or delivers the secure command to the secure resource for processing. In an embodiment, control device maintains audit records/audit trail, which is maintained on the control device.Type: GrantFiled: September 29, 2020Date of Patent: September 24, 2024Assignee: NCR Atleos CorporationInventor: Jeffrey Stephen Cooper
