Patent number: 11571306Abstract: Features for a restraint to facilitate delivery and deployment of an implantable cardiac device are described. The restraint may include a series of circumferential engagements for securing inwardly corresponding portions of the implant. The restraint may be located inside the implant and provide a radially inward force on the implant. The restraint may include a center shaft having a series of grooves configured to cooperate with corresponding splines of the implant. Distal or proximal advance of the restraint disengages the restraint from the implant. The implant may include a tubular frame configured to contract and be secured by the restraint in a contracted configuration and to expand upon disengagement from the restraint. The restraint may provide for a smaller overall cross-sectional profile of a transcatheter delivery system, for instance by negating the need for a distal delivery sheath.Type: GrantFiled: October 21, 2019Date of Patent: February 7, 2023Assignee: Boston Scientific Scimed, Inc.Inventors: Kenny Dwight Bruner, Padraig J. Savage, Matthew Rust, Christopher Lashinski, Nathan D. Brown, Michael J. Lee

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. Lee, Nathan D. Brown

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. Lee, Patrick E. Macaulay, Kenny D. Bruner, Padraig J. Savage, Nathan D. Brown

Patent number: 9060820Abstract: A segmented bone fixation device is provided with an elongate body having a longitudinal axis and having a first state in which at least a portion of the body is flexible and a second state in which the body is generally rigid. Methods of repairing a fracture of a bone are also disclosed. One such method comprises inserting a segmented fixation device into an intramedullary space of the bone to place at least a portion of the fixation device in a flexible state on one side of the fracture, providing rigidity across the fracture, and operating an actuator to deploy at least one gripper to engage an inner surface of the intramedullary space to anchor the fixation device to the bone. Various configurations allow a segmented device body to change shape as it moves from a flexible state to a rigid state.Type: GrantFiled: September 13, 2012Date of Patent: June 23, 2015Assignee: Sonoma Orthopedic Products, Inc.Inventors: Charles L. Nelson, Trung Ho Pham, Vernon R. Hartdegen, Jr., Nathan D. Brown
