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.

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: 10881540Abstract: An implantable stent includes multiple circumferential segments that surround a bore and are connected in series along a length to form a tubular wall. Multiple adjacent alternating opposite facing crowns arranged along each segment's circumference are bridged by struts. The struts include a series of staggered arcuate edges with limited flats to provide a limited region of maximum width between significantly extended reducing diameter tapers at either end where they transition into the crowns. Connections between adjacent segments are wider and stiffer than the struts and strut-crown transitions in the segments. The crowns include inner and outer radii with off-set centers along a common axis to provide medial crown peaks along the axis that are wider than the narrowed crown shoulders on either side of the axis and from which the tapered struts extend. Material strain and flexure along the stent during lateral bending is distributed mainly within the segments, e.g.Type: GrantFiled: May 3, 2019Date of Patent: January 5, 2021Assignee: CELONOVA BIOSCIENCES, INC.Inventors: Michael J.

Patent number: 10595985Abstract: Described are methods and apparatus for use in supporting tissue in a patient's body. In some embodiments, the patient's breast or another tissue is supported. One method involves introducing a superior soft tissue anchor into a patient, the anchor having an inferiorly facing total surface area; and introducing at least one inferior soft tissue anchor into the patient, such that the at least one inferior soft tissue anchor is suspended from the superior soft tissue anchor, the sum of all of the at least one inferior soft tissue anchors having a superiorly facing total surface area. The inferiorly facing total surface area of the superior anchor can be greater, such as at least two times greater than the superiorly facing total surface area of the at least one inferior anchor.Type: GrantFiled: September 15, 2017Date of Patent: March 24, 2020Assignee: Sinclair Pharmaceuticals LimitedInventors: Michael J.

Patent number: 10490374Abstract: One embodiment of the invention includes a phase-change material switch. The switch includes a first terminal that receives an input signal and a second terminal. The switch includes an actuation portion that receives a control signal in one of a first state to emit a first heat profile and a second state to emit a second heat profile. The switch further includes a switch portion comprising a phase-change material arranged as a plurality of longitudinal strips that each interconnect the first terminal and the second terminal and that are each in proximity with the actuation portion. The phase-change material can be selectable between a conducting state in response to the first heat profile to conduct an input signal from the first terminal to the second terminal and a blocking state in response to the second heat profile to block the input signal from the first terminal to the second terminal.Type: GrantFiled: September 12, 2014Date of Patent: November 26, 2019Assignee: NORTHROP GRUMMAN SYSTEMS CORPORATIONInventors: Pavel Borodulin, Nabil Abdel-Meguid El-Hinnawy, Robert Miles Young, Matthew Russell King, Michael J.
