Patent number: 11918462Abstract: Features for a heart valve device are described. The device may include a frame with anchors configured to secure the device to tissue. The frame may include a flared end or skirt for additional securement of the implanted device. The device may include a seal such as a barrier and/or cuff for preventing leakage. The device may contract for endovascular delivery of the device to the heart and expand for securement within the heart, such as the within the native mitral valve annulus. The device may include a replacement valve. The valve may have leaflets configured to re-direct blood flow along a primary flow axis.Type: GrantFiled: January 25, 2021Date of Patent: March 5, 2024Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Randall Lashinski, Matthew Rust, Patrick Macaulay, Richard Glenn

Publication number: 20230157823Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those heart valve implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. Anchors secure the implant to tissue and collars are used to decrease the angle between the struts and contract the frame. The implant thus expands from a first size inside of a delivery catheter, to a second and larger deployed size inside the heart to engage and anchor with the tissue, and then to a third and contracted size to re-size the annulus and/or provide a secure fit for a replacement heart valve. Various delivery systems including imaging capabilities for precise delivery, positioning and anchoring of the various implants are further described.Type: ApplicationFiled: January 10, 2023Publication date: May 25, 2023Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Randall Lashinski, Kristian Kristoffersen, Matthew Rust, Richard Glenn, Terry Wayne Daniels, Michael Lee, Patrick Macaulay

Patent number: 11523905Abstract: Features for a restraint, such as a cap, are described. The restraint secures a cardiac device in a collapsed, delivery configuration for transcatheter delivery to a heart. The restraint may have a tubular sidewall extending from a proximal end to a distal end, a proximal opening defined by the sidewall at the proximal end and a channel defined by the sidewall and extending distally from the proximal opening. The restraint is configured to receive the implant in the collapsed configuration through the proximal opening to radially restrain the implant within the channel. The restraint eliminates the need for a surrounding sheath, reducing the delivery profile and size of the overall delivery system, among other advantages. The restraint may have an atraumatic leading edge to reduce the risk of injury to the patient.Type: GrantFiled: July 17, 2019Date of Patent: December 13, 2022Assignee: Boston Scientific Scimed, Inc.Inventors: Erik Christopher Griswold, Christopher Robert Lashinski, Randall Lashinski, Michael J.

Patent number: 11432927Abstract: Systems, devices and methods related to various heart valve implants and for delivery of those implants are described. The implants may be used to re-size a native valve annulus or to replace a native heart valve. The implants include a re-sizable frame having angled struts. The implant is secured to tissue with anchors that can rotate without axial advancement to engage tissue while drawing the implant closer to the tissue. Collars are used to decrease the angle between struts of a frame to contract the implant. The implants can include a rotatable shaft, such as a threaded shaft, located internally to an axially translatable collar. Rotation of the shaft transmits force to the collar to cause the collar to translate axially, closing the angle of adjacent struts and decreasing the width of the implant and thus of the annulus. The implants can be delivered, secured and contracted via a catheter. The implants are repositionable and retrievable via catheter.Type: GrantFiled: December 18, 2019Date of Patent: September 6, 2022Assignee: Boston Scientific Scimed, Inc.Inventors: Randall Lashinski, Kristian Kristoffersen, Matthew Rust, Richard Glenn, Michael J.

Patent number: 11241309Abstract: Methods related to delivery of various heart valve implants are described. The implant may be delivered using an ultrasound imaging delivery system. The ultrasound imaging delivery system may be used to deliver a variety of different devices, including mitral valve reshaping devices, mitral valve replacement valves, and others. A deployment catheter carrying an implant having a tissue anchor is advanced to a deployment site in a heart. An imaging element is positioned adjacent the implant and a relationship between the tissue anchor and an anatomical landmark in the heart is visualized. The implant is then attached by driving the tissue anchor into tissue in the heart.Type: GrantFiled: June 5, 2019Date of Patent: February 8, 2022Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Randall Lashinski, Kristian Kristoffersen, Matthew Rust, Richard Glenn, Michael Lee, Patrick Macaulay
