Patent number: 12290646Abstract: A deflectable catheter is disclosed that includes a proximal handle, an elongated catheter shaft extending distally from the proximal handle and including a deflectable distal end portion, a drive mechanism associated with the proximal handle for deflecting the distal end portion of the catheter shaft between a first position where the distal end portion of the catheter shaft is aligned with an axis of the catheter shaft and a second position where the distal end portion of the catheter shaft is deflected angularly away from the axis of the catheter shaft, and indicator means associated with the drive mechanism for providing a visual indication of the position of the drive mechanism, which corresponds to a degree of curved deflection of the deflectable distal end portion of the catheter shaft.Type: GrantFiled: July 15, 2021Date of Patent: May 6, 2025Assignee: Oscor Inc.Inventors: Thomas P. Osypka, Andrew J. Enerson, Michael John Gelineau, Chet Michael

Publication number: 20250108188Abstract: In various examples, a vascular introducer is described. The vascular introducer includes a proximal housing defining an axial passageway. An elongated tubular sheath extends distally from the proximal housing and includes a sheath wall defining a central lumen. The central lumen of the tubular sheath includes an unexpanded configuration and an expanded configuration. The central lumen in the unexpanded configuration includes a first inner diameter, and the central lumen in the expanded configuration includes a second inner diameter, the second inner diameter being larger than the first inner diameter. The tubular sheath includes a plurality of circumferentially spaced apart elongated struts disposed partially within the sheath wall, such that an exposed portion of each of the plurality of struts extends radially inwardly from an inner surface of the sheath wall into the central lumen.Type: ApplicationFiled: September 26, 2024Publication date: April 3, 2025Inventors: Andrew J. Enerson, Jason Schinis, Kameron Ely

Patent number: 11938278Abstract: A vascular introducer system includes a first vascular introducer having an elongated first deflectable catheter sheath defining a lumen having an interior surface with an inner diameter. A tubular insert having a polygonal cross-section is associated with the interior lumen of the first catheter sheath. The system includes a second vascular introducer having an elongated second deflectable catheter sheath defining an exterior surface with an outer diameter that is less than the inner diameter of the interior surface of the first catheter sheath.Type: GrantFiled: April 6, 2021Date of Patent: March 26, 2024Assignee: Oscor Inc.Inventors: Andrew J. Enerson, Thomas P. Osypka

Publication number: 20220249804Abstract: A steerable intravascular catheter includes a handle assembly having opposed proximal and distal end portions and defining a longitudinal axis therebetween. An elongated sheath extending from the distal end portion of the handle assembly has opposed proximal and distal end portions, and includes a tubular body wall forming a central lumen for accommodating the introduction of a device and a fluid lumen radially outward from and parallel to the central lumen. The distal end portion of the elongated sheath is deflectable relative to the proximal end portion of the elongated sheath. A rotatable actuation assembly is associated with the handle assembly for controlling deflection of the distal end portion of the elongated sheath. An inflatable occlusion balloon is positioned on an outer surface of the distal end portion of the elongated sheath. The fluid lumen of the elongated sheath is in fluid communication with an interior of the balloon.Type: ApplicationFiled: April 25, 2022Publication date: August 11, 2022Inventors: Thomas P. Osypka, Jorg TeBarek, Andrew J. Enerson, Chet Michael
