Publication number: 20230389908Abstract: A latch locking and release system having a control knob operably coupled with a latch system, and a tubular latch release mechanism. The cross-section of the tubular latch release mechanism is shiftable between a locking configuration and a release configuration. In the locking configuration, the control knob maintains latches in the latch system in an engaged configuration, and is blocked from moving to allow the latches to be disengaged. In the release configuration, the control knob may be moved to allow the latches to be disengaged. The latch release mechanism and control knob may have further features preventing inadvertent actuation of the latch locking and release system to allow the latch system to be disengaged.Type: ApplicationFiled: June 1, 2023Publication date: December 7, 2023Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Joshua Mark Inouye, Graham Krumpelmann, James M.

Patent number: 11642221Abstract: An implant includes a frame comprising a tubular body formed by a plurality of interconnected struts that are manufactured to reduce stresses and strains resulting from component interaction during chronic use. At least a portion of a longitudinal corner of one or more struts of the frame may be chamfered, rounded, or otherwise modified to distribute stresses experienced at the strut corner throughout the strut body. Chamfering and/or rounding corners along at least a portion of a strut of the frame may reduce stresses on the frame caused by interactions between the frame and other components of the implant. The implant may be manufactured by cutting (e.g., laser cutting) a plurality of struts from a tubular metal alloy, polymer, or the like forming the tubular body, and softening at least a portion of an edge of the strut by cutting, grinding, and/or micro-blasting the edges of the corner.Type: GrantFiled: December 17, 2020Date of Patent: May 9, 2023Assignee: Boston Scientific Scimed, Inc.Inventors: Burns Doran, Kelsey Cooper, Graham Krumpelmann, Ted Pelzer, Joshua Mark Inouye, Mark McPhail

Patent number: 11540919Abstract: A low profile implant, system and method of deployment includes a frame comprising an elongate body having ends that overlap to form an annular configuration of the frame. A circumference of the frame may be modified by varying an extent of the overlap between the ends of the elongate body. The elongate structure may extend through a sleeve of a number of respective anchor housings of the implant along a first axis, and anchors may be deployed through bores in the anchor housings along a second axis to secure the anchor housings to tissue. The implant may be deployed about and anchored to a valve annulus, and the circumference of the frame, and associated anchored tissue, may be adjusted to reconfigure the valve annulus.Type: GrantFiled: December 17, 2020Date of Patent: January 3, 2023Assignee: Boston Scientific Scimed, Inc.Inventors: Graham Krumpelmann, Joshua M.
