Patent number: 11918227Abstract: Devices, methods and systems are provided for occluding an opening within the tissue of a body, such as a left atrial appendage. In one embodiment, a medical device includes an occluder portion and an anchor portion. The occluder portion includes a hub that defines an axis, the occluder portion extending between a proximal end coupled to the hub and a distal end defining an occluder eyelet adjacent thereto. The anchor portion extends between a first end and a second end, the first end coupled to an anchor hub and the second end defining an anchor eyelet adjacent thereto and hingeably coupled to the occluder eyelet. With this arrangement, the anchor hub is moveable along the axis to move the anchor portion between a retracted position and a deployed position upon the occluder portion being in an expanded position.Type: GrantFiled: April 27, 2020Date of Patent: March 5, 2024Assignee: Coherex Medical, Inc.Inventors: Daryl R.

Publication number: 20180292727Abstract: The present subject matter includes apparatus and techniques that can be used to reduce losses in systems that perform steering of a light beam. Such steering can be performed in a non-mechanical manner, such as using an electrically-controlled optical structure (e.g., an electro-optical structure). For example, a waveguide can be used to adjust an angle of a light beam (e.g., steer the light beam). The waveguide can include a core, a cladding including an electro-optic material, and electrodes defining an arrangement that, when selectively energized, adjusts an index of refraction of the electro-optic material. In particular, electrode arrangements as described herein can be used to reduce losses, such as losses that would occur due to diffraction.Type: ApplicationFiled: April 5, 2017Publication date: October 11, 2018Inventors: Michael Ziemkiewicz, Scott R.

Patent number: 8995038Abstract: An optical time delay control device for controllably altering the transit time of an optical beam between two points. In one example, the device may include an optically transparent solid medium for receiving the optical beam, wherein at least a portion of the medium is generally a parallel piped shape characterized by a height, length and width, wherein the length is larger than the height; two mirrors affixed to two opposing parallel surfaces of the optically transparent solid medium, so that during operation the optical beam reflects between the two mirrors as the optical beam travels through the optically transparent medium; and an angle actuator for controllably altering the angle at which the optical beam enters into the optically transparent medium, thereby controllably altering the time that the optical beam travels through the device. This in effect permits control of the amount of delay of the transmission of light, and delays of 20 nanoseconds have been achieved.Type: GrantFiled: July 6, 2011Date of Patent: March 31, 2015Assignee: Vescent Photonics, Inc.Inventors: Michael H.

Patent number: 8380025Abstract: Liquid crystal waveguides for dynamically controlling the refraction of light. Generally, liquid crystal materials may be disposed within a waveguide in a cladding proximate or adjacent to a core layer of the waveguide.
