Patent number: 11941033Abstract: The disclosure is directed at a method and system for improved search functionality. By using natural language processing (NLP), individual words in a search term may be parsed and then individually stored. The relationships between the individual words of the search term may also be stored such that when the search is repeated, the previous results may be retrieved and, if not, a more accurate search may be performed.Type: GrantFiled: November 27, 2018Date of Patent: March 26, 2024Assignee: Affirm, Inc.Inventors: Qi Zhu, Sean Weisman, Gregory Ward, Alishan Ladhani, Jeff Li

Patent number: 11701012Abstract: A catheter, such as a fractional flow reserve catheter, includes an elongate shaft having a pressure sensing wire extending to the distal portion of the elongate shaft. The wire has a pressure sensor mounted on the distal end for measuring a pressure of a fluid within lumen of vessel. The pressure sensor wire is disposed within a pocket formed adjacent to the pressure sensor thereby minimizing the profile of the catheter. Bending stresses experienced by a pressure sensor mounted to a fractional flow reserve catheter when tracking the catheter through the vasculature creates a distortion of the sensor resulting in an incorrect pressure reading or bend error. In order to isolate the sensor from bending stresses, the sensor is spaced apart from the pressure sensor wire to allow the pressure sensor and the pressure sensor wire to move independently from one another.Type: GrantFiled: February 16, 2021Date of Patent: July 18, 2023Assignee: MEDTRONIC VASCULAR, INC.Inventors: Gerry McCaffrey, Christopher Murphy, Sean Ward, Fiachra Sweeney

Patent number: 11378123Abstract: In accordance with one aspect of the present disclosure, a turbocharger having a rolling element bearing (REB) assembly contained within a bearing housing includes an axial damper configured to dampen and limit axial displacement of the REB assembly. The axial damper can include different embodiments, including an elastomeric axial damper, wire mesh, or oil film, for interrupting contact between the bearing assembly and a displacement limit when an axial displacement force exceeds a preload force. Further, the axial damper can include an apparatus having at least two axially compressible rings, where one of the axially compressible rings includes a displacement limit feature.Type: GrantFiled: December 18, 2019Date of Patent: July 5, 2022Assignee: BorgWarner Inc.Inventors: Allan Douglas Kelly, Kurt Henderson, Michael Sean Ward

Publication number: 20220192703Abstract: A guide extension catheter assembly including a guide extension catheter and a support device. The guide extension catheter includes a shaft and a tubular member. The support device includes a push member and a shuttle member. The guide extension catheter assembly is configured to selectively provide a delivery state in which at least a portion of the shuttle member is disposed within the lumen, a leading end of the shuttle member is distal a distal end of the tubular member, and the shuttle member is directly, physically connected to the tubular member. In the delivery state, a longitudinal distal force applied to the push member is transferred to the tubular member as a longitudinal distal force via the shuttle member. The guide extension catheter assemblies of the present disclosure can promote a two stage guide extension catheter deployment.Type: ApplicationFiled: March 9, 2022Publication date: June 23, 2022Applicant: Medtronic Vascular, Inc.Inventors: Barry O'Connell, Sean Ward, John K.

Patent number: 11330994Abstract: A catheter includes a proximal shaft, a distal shaft, a pressure sensor, and at least one pressure sensor wire. The proximal shaft is substantially C-shaped such that in cross-section, the proximal shaft includes a first circumferential end, a second circumferential end, and a gap between the first circumferential and circumferential end. The proximal shaft defines a groove configured to receive a guidewire therein. The distal shaft is coupled to the proximal shaft and defines a guidewire lumen therein. The pressure sensor is coupled to the distal shaft. The pressure sensor wire is operably connected to the pressure sensor. A proximal portion of the pressure sensor wire is disposed within a proximal shaft wall of the proximal shaft and a distal portion of the pressure sensor wire is disposed within a distal shaft wall of the distal shaft.Type: GrantFiled: March 8, 2017Date of Patent: May 17, 2022Assignee: Medtronic Vascular, Inc.Inventors: Ronan Rogers, Matthew Fleming, Ronan Finn, Timothy Jones, Francis McEvoy, Joshua Hillas, James Keaveney, Sean Ward, H.

Publication number: 20220054829Abstract: A tool has an outer assembly, which includes a deployment tube, extending around, and moveable with respect to an inner assembly of the tool; the inner assembly includes a single pull wire and a distal member configured to engage an end of an implantable medical device. The deployment tube includes an articulating segment located just proximal to an enlarged distal-most portion, which contains the device and the distal member. Relatively soft and stiff sections of a composite sidewall define the articulating segment and extend alongside one another, such that, when the pull wire is actuated, the composite sidewall causes bending of the segment in two directions. A handle assembly of the tool includes a control member for the pull wire, and may further include a flushing subassembly that has a connector port located at an end of the handle assembly that is opposite a proximal port of the handle.Type: ApplicationFiled: September 3, 2021Publication date: February 24, 2022Inventors: Sean Ward, Rónán P.

Patent number: 10758729Abstract: In a system for retrieving an implanted device, a flared inner surface of a catheter tubular sidewall may define a distal-most opening of a device receptacle; the opening has a first diameter equal to that of the receptacle, and a second diameter, coincident with a distal-most edge of the tubular sidewall, and at least 5% greater than the receptacle diameter. Alternately, a retrieval tool in sliding engagement within a lumen of a catheter includes a shaft assembly, through which a snare member passes, and which includes a collapsible spring-biased perimeter sidewall; the sidewall defines a capture member passageway approximately coaxial, and in fluid communication with a lumen of the shaft assembly. A distal-most opening of the passageway has a spring-biased diameter that is greater than that of a distal-most opening of a device receptacle of the catheter, and a collapsed diameter that is less than the receptacle distal-most opening diameter.Type: GrantFiled: October 1, 2015Date of Patent: September 1, 2020Assignee: Medtronic, Inc.Inventors: Paula McDonnell, Brendan P Geraghty, Gwenda Francis, Rónán Wood, Sean Ward, Pat McHugh, Tomas K Kelly
