Patent number: 11571296Abstract: A prosthetic heart valve includes a collapsible and expandable stent with a valve assembly disposed therein. A first cuff is positioned on the lumenal or ablumenal surface of the stent. A second cuff is positioned radially outward of the stent and the first cuff. The second cuff may include apertures that allow blood to pass through the second cuff into the spaces between the first and second cuffs. The second cuff may include a proximal edge with a plurality of notches that may be closed to create puckered areas in the second cuff to facilitate the movement of blood in the spaces between the first and second cuffs. The stent may include struts adjacent the second cuff that bow radially inwardly to create additional space for blood to flow in the spaces between the first and second cuffs.Type: GrantFiled: August 27, 2019Date of Patent: February 7, 2023Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Richard Kaleta, Keith High

Patent number: 11534296Abstract: A loading assembly for crimping and loading a prosthetic heart valve into a delivery device includes a loading base, a base funnel, and a compression member. The loading base has a support and a body extending from the support with a recess defined within the body. The recess is configured to receive a substantial portion of the annulus section of the heart valve in an at least partially collapsed condition. The base funnel is configured to be coupled to the loading base and to at least partially collapse the annulus section of the heart valve as it is inserted into the recess in the loading base. The compression member is configured to be coupled to the loading base with the heart valve inserted in the recess for further collapsing the heart valve and loading it into the delivery device.Type: GrantFiled: January 21, 2020Date of Patent: December 27, 2022Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Kristen T. Morin, Keith High, Ian Wright

Patent number: 11096812Abstract: A delivery system has a delivery capsule with a detachable portion including first and second open ends with a tapered wall extending therebetween to compress and guide a collapsible heart valve into the delivery capsule. The detachable portion may be detached from the delivery capsule after loading the collapsible heart valve to leave a smooth distal surface on the delivery capsule. Detachment of the detachable portion may occur by breaking or removing a frangible member interposed between the detachable portion and the delivery capsule.Type: GrantFiled: December 26, 2018Date of Patent: August 24, 2021Assignee: St. Jude Medical, Cardiology Division, Inc.Inventors: Ryan Finn, Keith High

Patent number: 10722357Abstract: An assembly for loading a self-expanding prosthetic heart valve into a delivery device includes a support member including a body and a backing plate. The body has a longitudinal axis, a base end, a second end, and a recess extending along the longitudinal axis from the second end toward the base end. The recess has a bottom member defining a seating surface adapted to support the prosthetic heart valve. The backing plate is fixed to the body so as to define a void space between the backing plate and the body. The backing plate includes an inlet port and the recess includes a plurality of outlet ports. The inlet and outlet ports are in fluid communication with the void space. When the heart valve is received on the seating surface, each outlet port is rotationally aligned with a corresponding pocket formed between first and second cuffs of the heart valve.Type: GrantFiled: July 17, 2018Date of Patent: July 28, 2020Assignee: St. Jude Medical, Cardiology Division, Inc.Inventor: Keith High

Publication number: 20110054340Abstract: A wound dressing can include an adhesive dressing with a diaphragm vent that allows the passage of gas out of a patient's body but restricts the flow of gas into the body. A sensor device is positioned so as to be able to sample gas passing through the vent and measure one or more gas characteristics, such as temperature, humidity, and/or pressure. If the data from the sensor device exceeds certain parameters suggestive of a pneumothorax, a processing device can activate an alert system, such as an indicator light, audible alarm, and/or wireless signal, to alert the care provider.Type: ApplicationFiled: August 6, 2010Publication date: March 3, 2011Applicant: COMBAT MEDICAL SYSTEMS, LLC.Inventors: Corey Russ, Christopher Murphy, Brian Farrell, Keith High, Sean Mahoney
