Patent number: 12268813Abstract: A device for biofilm removal from an endotracheal tube is disclosed. Such a device may include a hollow catheter having a tip, wherein said device is inserted down an endotracheal tube of an orally intubated patient. Said tip may include a cylindrical central portion and a fin configured to dislodge biofilm from the inner lumen of the endotracheal tube as the device is rotated, either manually or mechanically, inside the endotracheal tube. The fin may be configured as a helix and positioned to spiral around said cylindrical central portion of the tip thereby forming a channel, defined by the pitch of said helix, about the circumference of the cylindrical central portion. Biofilm dislodged from the inner surface of the endotracheal tube by the rotational motion of the fin may be retained within the channel until the tip is removed from the endotracheal tube. The device may further comprise a motor for mechanically rotating the catheter and tip.Type: GrantFiled: October 22, 2021Date of Patent: April 8, 2025Inventors: Morgan Bohrer, Stephen Hahn, Michael L'Ecuyer, Alexandra Verne

Patent number: 11960881Abstract: A system and method for simplifying the creation of documentation, and especially software documentation. A software application, referred to as a source metadata tagger and document compiler is used to add metadata to a final output document. This metadata contains identifiers that are associated with various source files. In this way, the system can easily determine which source file is being reviewed and/or flagged by the reviewer. This information can be used by the ticketing/notification system to create a work item for the appropriate developer or development group. This is vastly simpler than the current system, where human intervention is required to determine which source file is being flagged.Type: GrantFiled: January 24, 2020Date of Patent: April 16, 2024Assignee: Silicon Laboratories Inc.Inventors: Nicholas Ryan Wellinghoff, Stephen Hahn, Yi-Yang Chen, Bradford Stewart

Publication number: 20070142866Abstract: A cardiac rhythm management (CRM) system includes an implantable medical device that delivers anti-tachyarrhythmia therapies including anti-tachyarrhythmia pacing (ATP) and at least one hemodynamic sensor that senses a hemodynamic signal. When a tachyarrhythmia episode is detected, the CRM system analyzes the hemodynamic signal to determine whether and/or when to deliver an ATP. In one embodiment, a hemodynamic parameter extracted from the hemodynamic signal is used to predict the potential effective of ATP in terminating the detected tachyarrhythmia episode. In another embodiment, a characteristic feature detected from the hemodynamic signal is used to determine an ATP window during which a delivery of ATP is initiated.Type: ApplicationFiled: December 20, 2005Publication date: June 21, 2007Inventors: Dan Li, Gerrard Carlson, Stephen Hahn
