Publication number: 20250120810Abstract: Disclosed herein are expandable introducer sheaths and methods of making and using the same. The sheaths minimize trauma to a patient's vasculature by allowing for temporary expansion of a portion of the sheath to accommodate passage of a delivery system for an implant, then return to a non-expanded state after the passage of the device. The sheath includes a foldable inner member having a detached flap structure at its distal tip that facilitates expansion of the sheath lumen to increased diameters, and an elastomeric distal end that reduces push and retrieval forces therethrough. The sheath can include a hemostasis seal on its proximal end to prevent the leakage of blood out of the sheath and prevent ballooning of outer layer of the sheath.Type: ApplicationFiled: December 20, 2024Publication date: April 17, 2025Inventors: Thanh Huy Le, Tung T. Le, Sovanpheap Mak, Alpana Kiran Gowdar, Richard D. White, Sonny Tran

Patent number: 12249025Abstract: Systems and methods are disclosed for calculating dynamic ambient occlusion (AO) values for character models to yield high-quality approximations of global illumination effects. The approach utilizes a dual component machine-learning model that factorizes dynamic AO computation into a non-linear component, in which visibility is determined by approximating spheres and their casted shadows, and a linear component that leverages a skinning-like algorithm for efficiency. The parameters of both components are trained in a regression against ground-truth AO values. The resulting model accommodates lighting interactions with external objects and can be generalized without requiring carefully constructed training data.Type: GrantFiled: December 4, 2023Date of Patent: March 11, 2025Assignee: Electronic Arts Inc.Inventors: Binh Huy Le, John Peter Lewis

Publication number: 20250041721Abstract: A server employs a shared raytracing context to generate video streams for multiple client devices. The server uses the shared raytracing context to perform raytracing operations for each of the client devices, and based on the raytracing operations generates different sets of image frames. The server then streams each set of image frames to a corresponding client device over a network.Type: ApplicationFiled: December 5, 2023Publication date: February 6, 2025Inventors: Aaron Michael Knoll, Binh Huy Le, Madhusudhanan Srinivasan, Mark Richard Nutter

Patent number: 12194256Abstract: A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.Type: GrantFiled: August 8, 2022Date of Patent: January 14, 2025Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Pu Zhou, Erik Bulman, Timothy A.

Publication number: 20240216139Abstract: Devices and methods for crimping a prosthetic heart valve onto a delivery device are described. In some embodiments, valves are crimped over an inflatable balloon and between proximal and distal shoulders mounted on a shaft inside the balloon. Crimping methods can include multiple compression steps with the valve located in different axial positions relative to the crimping jaws at each different step. In some methods, the valve may extend partially outside of the crimping jaws during certain crimping steps, such that the crimping force is only applied to the part of the valve that is inside the jaws. Exemplary crimping devices can include two or more adjacent sets of jaws that close down to different inner diameters, such that different parts of a valve get compressed to different outer diameters at the same time during a single crimping step.Type: ApplicationFiled: March 15, 2024Publication date: July 4, 2024Inventors: Nicholas Brandon Aders, Kristen Hicks, Gil Senesh, Michael R.

Patent number: 12011351Abstract: A valve catheter is advanced through a patient's vasculature while a prosthetic heart valve is attached to flexible extensions along a distal end thereof. The valve catheter is advanced through a tubular sleeve for exposing the prosthetic heart valve and allowing the prosthetic heart valve to self-expand while the extensions remain attached to the prosthetic heart valve. A release mechanism on a handle portion is actuated for releasing the prosthetic heart valve from the extensions, thereby implanting the prosthetic heart in a native heart valve. If the operator is not satisfied with the initial expansion, the prosthetic heart valve may be reoriented before release from the extensions by retracting the prosthetic heart valve back into the tubular sleeve, adjusting the orientation of the prosthetic heart valve and then re-advancing the valve catheter from the tubular sleeve for allowing the prosthetic heart valve to re-self-expand at a more desirable location.Type: GrantFiled: April 15, 2020Date of Patent: June 18, 2024Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: Henry Bourang, Thanh Huy Le, David M. Taylor, Sam Sok, Mario Iobbi, David J. Evans, Rajesh A. Khanna
