Publication number: 20240138981Abstract: Delivery devices for delivering a self-expanding prosthetic heart valve are disclosed. The delivery device includes at least one cord is configured to selectively cinch the self-expanding prosthetic heart valve. The delivery device further includes at least one self-expanding release pin comprising a proximal segment, a distal segment, and an intermediate segment positioned between the proximal segment and the distal segment. The at least one self-expanding release pin includes a normal, expanded condition wherein the intermediate segment extends radially outward relative to a central axis of the spindle from the proximal segment to the distal segment. The delivery device further includes a capsule configured to be distally extended relative to the spindle to collapse the at least one self-expanding release pin from the normal, expanded condition of the at least one self-expanding release pin to a collapsed condition of the at least one self-expanding release pin.Type: ApplicationFiled: January 11, 2024Publication date: May 2, 2024Inventors: Jill Mendelson, Michele Silver, Michael Gloss, Timothy Groen, Paul Rothstein, Jeffrey Sandstrom, Phil Haarstad, Joel Racchini, David Blaeser

Patent number: 11957581Abstract: A system for replacing a heart valve of a patient. The system includes a delivery device and a prosthetic heart valve. The system is configured to be transitionable between a loaded state, a partially deployed state and a deployed state. In the loaded state, the prosthetic heart valve engages a coupling structure and is compressively retained within a primary capsule, which constrains the prosthetic heart valve in a compressed arrangement. In the partially deployed state, the prosthetic heart valve engages the coupling structure and is compressively retained within a secondary capsule, which constrains the prosthetic heart valve to a partially deployed arrangement. The partially deployed arrangement is less compressed than the compressed arrangement and less expanded than a deployed arrangement. In the deployed state, the primary and secondary capsules are retracted from over the prosthetic heart valve, which expands to the deployed arrangement and is released from the coupling structure.Type: GrantFiled: February 5, 2021Date of Patent: April 16, 2024Assignee: MEDTRONIC, INC.Inventors: Joel Racchini, Paul Rothstein, Jeffrey Sandstrom

Patent number: 11931257Abstract: Aspects of the disclosure relate to devices and methods for preparing an existing, implanted prosthetic aortic valve for subsequent prosthetic aortic valve implantation. To prepare the existing valve, a valve preparation device is delivered to the valve and valve leaflets are severed either via mechanical cutting or electrodes so that the leaflets cannot obstruct a blood flow path once a prosthetic valve is subsequently implanted within the valve. Similarly, in alternate embodiments, devices and methods of the disclosure can be used for preparing a native aortic valve for delivery and implantation of a prosthetic valve.Type: GrantFiled: March 26, 2019Date of Patent: March 19, 2024Assignee: MEDTRONIC, INC.Inventors: Jorge Zhingre Sanchez, Anthony Nesberg, Erik Jagger, Jeffrey Sandstrom, Vijayanarayan Madhavan Potti, Jacob McHenry, Michael Bateman, Ryan Stublaski, Ana Menk, Paul Rothstein, Joel Racchini

Patent number: 8866603Abstract: A method, a device and a system for communicating in a vehicle at least one deviation of a measured actual vehicle parameter value from its predetermined value to a driver involve determining an amount of the deviation, color-coding the amount of deviation, and communicating the amount of deviation to the driver by using the color-code. Determining the amount of deviation includes weighting a calculated difference between the measured actual vehicle parameter value and the predetermined vehicle parameter value with a weighting factor. A vehicle or more particularly a truck may include such a device and such a system and a computer programmed for performing such a method and computer readable medium comprising a program for performing such a method can be provided.Type: GrantFiled: September 17, 2007Date of Patent: October 21, 2014Assignee: Volvo Technology CorporationInventors: Joel Sandström, Emma Rozada

Patent number: 8524018Abstract: A primer composition that includes stabilized, encapsulated red phosphorus, at least one oxidizer, at least one secondary explosive composition, at least one light metal, and at least one acid resistant binder. The stabilized, encapsulated red phosphorus may include particles of red phosphorus, a metal oxide coating, and a polymer layer. The metal oxide coating may be a coating of aluminum hydroxide, bismuth hydroxide, cadmium hydroxide, cerium hydroxide, chromium hydroxide, germanium hydroxide, magnesium hydroxide, manganese hydroxide, niobium hydroxide, silicon hydroxide, tin hydroxide, titanium hydroxide, zinc hydroxide, zirconium hydroxide, or mixtures thereof. The polymer layer may be a layer of epoxy resin, melamine resin, phenol formaldehyde resin, polyurethane resin, or mixtures thereof. A percussion cap primer that includes the primer composition, a tertiary explosive composition, and a cup is also disclosed, as are ordnance devices including the primer composition.Type: GrantFiled: December 23, 2010Date of Patent: September 3, 2013Assignee: Alliant Techsystems Inc.Inventors: Randall T. Busky, Tod R. Botcher, Joel Sandstrom, Jack Erickson

Patent number: 8470107Abstract: A non-toxic, non-hydroscopic percussion primer composition and methods of preparing the same, including at least one explosive component that has been traditionally considered a moderately insensitive explosive or secondary explosive, and at least fuel particle component having a particle size of about 1.5 microns to about 12 microns, which allows the use of moderately active metal oxidizers. The sensitivity of the primer composition is created by the interaction between the moderately insensitive explosive and the fuel agent such that traditional primary explosives such as lead styphnate or DDNP are not needed. The primer composition also eliminates the risks and dangers associated with traditional nano-sized fuel particles.Type: GrantFiled: May 22, 2012Date of Patent: June 25, 2013Assignee: Alliant Techsystems Inc.Inventors: Joel Sandstrom, Aaron A.
