Patent number: 11982624Abstract: Carbon fiber characterization processes are described that include multi-condition Raman spectroscopy-based examination combined with multivariate data analyses. Methods are a nondestructive material characterization approach that can provide predictions as to carbon fiber bulk physical properties, as well as identification of unknown carbon fiber materials for quality control purposes. The framework of the multivariate analysis methods includes a principal component-based identification protocol including comparison of Raman spectral data from an unknown carbon fiber with a data library of multiple principal component spaces.Type: GrantFiled: October 26, 2020Date of Patent: May 14, 2024Assignee: Battelle Savannah River Alliance, LLCInventors: Amanda L. Houk, Matthew S. Wellons, Ross J. Smith, Joshua T. Hewitt

Publication number: 20220257317Abstract: A resurfacing device for removing a thin layer of diseased tissue while minimizing damage to the underlying tissue layers may include an expandable scaffold attached to a catheter shaft, at least one electrode disposed on the expandable scaffold, and a plurality of debridement elements disposed on an outer surface of the expandable scaffold. The expandable scaffold is positioned in apposition to the target tissue, the scaffold is expanded and the electrodes are activated to ablate diseased tissue. The scaffold is rotated to remove the ablated tissue.Type: ApplicationFiled: February 15, 2022Publication date: August 18, 2022Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: TRAVIS HENCHIE, JOSEPH W.

Publication number: 20210259691Abstract: This disclosure relates generally to the field of devices and procedures for forming an opening between adjacent tissue structures. For example, in an embodiment, a system for forming an opening between body lumens may include a delivery catheter. A first access element may be configured to be positioned against a first body lumen disposed about a distal end of the catheter. A second access element having an outer diameter that substantially matches an outer diameter of the first access element may be disposed about the distal end of the catheter. The second access element may be configured to be positioned against a second body lumen and axially aligned with the first access element. A filament may be electrically coupled to one or both of the first and second access element.Type: ApplicationFiled: February 18, 2021Publication date: August 26, 2021Inventors: Amanda L. Smith, John T. Favreau, Travis Henchie, Joseph W. King, Lauren Lydecker, Andrew Pic

Publication number: 20210128334Abstract: The present disclosure relates generally to the field of medical devices and medical device delivery. In particular, the present disclosure relates to medical devices, systems, and methods for delivering a barrier device within a body lumen of a patient, such as the GI tract. For example, a barrier device may include a distal self-expanding stent. A tubular barrier may have a proximal end, a distal end, and a lumen extending therethrough. The distal stent may be disposed at the distal end of the tubular barrier. An anchoring self-expanding stent may be disposed at the proximal end of the tubular barrier.Type: ApplicationFiled: November 4, 2020Publication date: May 6, 2021Inventors: John T. Favreau, Andrew Pic, Amanda L Smith, Lauren Lydecker, Travis Henchie
