Patent number: 9913706Abstract: Excessive dilation of the annulus of a mitral valve may lead to regurgitation of blood during ventricular contraction. This regurgitation may lead to a reduction in cardiac output. Disclosed are systems and methods relating to an implant configured for reshaping a mitral valve. The implant comprises a plurality of struts with anchors for tissue engagement. The implant is compressible to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter to embed its anchors to the tissue surrounding and/or including the mitral valve. The implant may then contract to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the mitral valve and lessening any of the associated symptoms including mitral regurgitation.Type: GrantFiled: August 29, 2017Date of Patent: March 13, 2018Assignee: Millipede, Inc.Inventors: Randall Lashinski, Matthew Rust, Patrick Macaulay, Terry Wayne Daniels, Kris Kristoffersen

Publication number: 20170267558Abstract: Techniques are described that relate to enhancing flocculation and dewatering of thick fine tailings, for example by reducing process oscillations. One example method includes dispersing a flocculant into thick fine tailings having a turbulent flow regime to produce turbulent flocculating tailings; subjecting the turbulent flocculating tailings to shear to build up flocs and increase yield stress, to produce a flocculated material having a non-turbulent flow regime; and shear conditioning the flocculated material to decrease the yield stress and produce conditioned flocculated tailings within a water release zone; and dewatering the conditioned flocculated tailings, for example by employing sub-aerial deposition. The thick fine tailings may have a Bingham Reynolds Number of at least 40,000 upon flocculant addition.Type: ApplicationFiled: May 30, 2017Publication date: September 21, 2017Inventors: TREVOR BUGG, ANA SANCHEZ, ADRIAN REVINGTON, JAMES PATRICK MACAULAY

Publication number: 20170135816Abstract: 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: November 15, 2016Publication date: May 18, 2017Inventors: Randall Lashinski, Kristian Kristoffersen, Matthew Rust, Richard Glenn, Terry Wayne Daniels, Michael Lee, Patrick Macaulay

Patent number: 9622862Abstract: Disclosed is an implantable mitral valve having an adjustable support. The support comprises a plurality of pairs of adjacent struts joined at apexes and a plurality of anchors for tissue engagement. The implant is adjustable to a first, reduced diameter for transluminal navigation and delivery to the left atrium of a heart. The implant may then expand to a second, enlarged diameter for the step of embedding the anchors into tissue surrounding and/or including the mitral valve. The implant may then be adjusted to a third, intermediate diameter, pulling the tissue radially inwardly, thereby reducing the native mitral valve annulus and supporting the prosthetic mitral valve.Type: GrantFiled: September 28, 2015Date of Patent: April 18, 2017Assignee: Millipede, Inc.Inventors: Randall Lashinski, Matthew Rust, Patrick Macaulay, Terry Wayne Daniels, Kris Kristoffersen

Publication number: 20170086974Abstract: 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: ApplicationFiled: September 29, 2016Publication date: March 30, 2017Inventors: Randall Lashinski, Kristian Kristoffersen, Matthew Rust, Richard Glenn, Michael Lee, Patrick Macaulay
