Ablative therapy may be performed within the inguinal canal to cause a fibrotic response resulting in scar tissue formation and/or tissue shrinkage that narrows the canal.Type: ApplicationFiled: April 3, 2020Publication date: April 15, 2021Inventor: David Keane

Publication number: 20210106418Abstract: Tissue anchors, kits that include a tissue anchor, and methods of anchoring tissue to a bone are described. An example embodiment of a tissue anchor includes a screw and a stem releasably attached to the screw. The screw defines a first opening, a second opening, and a lumen that extends from the first opening to the second opening. A portion of the stem is sized and configured to be received within the lumen defined by the screw.Type: ApplicationFiled: December 21, 2020Publication date: April 15, 2021Inventor: James Jastifer

Publication number: 20210106419Abstract: Fixation device for fixation of leaflets of a heart valve includes an elongate central member defining a longitudinal axis of the fixation device and first and second arms rotatable about at least one arm hinge point between an open position and a closed position. The fixation device further includes a first gripping element rotatable about a first gripping element axis of rotation to capture a first leaflet of a heart valve between the first gripping element and the first arm. The fixation device further includes a second gripping element rotatable about a second gripping element axis of rotation to capture a second leaflet of a heart valve between the second gripping element and the second arm. At least one of the first gripping element axis of rotation and the second gripping element axis of rotation is variably offset from the arm hinge point by an axis offset distance defined along the longitudinal axis.Type: ApplicationFiled: October 9, 2020Publication date: April 15, 2021Applicant: EVALVE, INC.Inventor: Chad Abunassar

Publication number: 20210106420Abstract: An implantable prosthetic valve can include a radially expandable and collapsible annular frame comprising an inflow end and an outflow end and a plurality of struts forming a plurality of cells, where each of the plurality of cells defines an opening in the frame. A leaflet structure can be positioned within the frame and secured thereto. A plurality of sealing members can be secured to the plurality of struts of the frame, where each sealing member of the plurality of sealing members includes two opposite sides that are not secured to the frame to allow blood to flow through each sealing member along a path formed between the frame and the sealing members.Type: ApplicationFiled: December 3, 2020Publication date: April 15, 2021Applicant: Edwards Lifesciences CorporationInventors: David Maimon, Tamir S. Levi

Publication number: 20210106421Abstract: A system including a self-expanding prosthesis configured to foreshorten during deployment thereof and a delivery device configured to percutaneously deliver the self-expanding prosthesis. The delivery device includes a handle having an actuator thereon, an outer sheath including a proximal end coupled to the handle and a pusher shaft slidingly disposed within the outer sheath. The pusher shaft has a proximal end coupled to the handle and a distal end configured to releasably couple to the self-expanding prosthesis such that the self-expanding prosthesis axially moves therewith. The inner shaft has a distal portion of the inner shaft that is configured to receive a self-expanding prosthesis thereon. The outer sheath and the pusher shaft are configured to simultaneously move in opposing axial directions via actuation of the actuator on the handle to compensate for the foreshortening of the self-expanding prosthesis during deployment.Type: ApplicationFiled: October 9, 2019Publication date: April 15, 2021Inventors: Stephen MONTGOMERY, Maro SCIACCHITANO

Publication number: 20210106422Abstract: An endovascular medical assembly and method for restoring chordal support to a leaflet of a heart valve by implanting artificial chordae tendinea in the heart. A chord is inserted into the heart endovascularly with a leaflet grasper which pierces the leaflet and implants the chord through the leaflet. An anchor assembly is implanted into an intracardiac wall and has anchor lines extending therefrom. The chord and an anchor line are assembled by a line gathering member and the tension of the chord is adjusted and secured. The chord is, thus, secured to the anchor assembly to support the leaflet.Type: ApplicationFiled: October 9, 2020Publication date: April 15, 2021Inventors: Vivek Rajagopal, Jaime Eduardo Sarabia, Yenchin Liao, Alfred Raschdorf

Publication number: 20210106423Abstract: An apparatus for deploying a tissue anchor is disclosed. The apparatus includes a catheter tube having a proximal end and a distal end defining the catheter's length, where the distal end has an anchor housing configured to hold a tissue anchor before deployment; and a pusher wire positioned within the catheter tube and extending through the length of the catheter tube. The apparatus is configured to provide a pushing force on the pusher wire from the proximal end of the catheter tube, thus displacing the pusher wire in a distal direction to the pusher wire's fully extended anchor deployment position which in turn deploys the tissue anchor from the anchor housing in the distal direction by pushing the tissue anchor in the distal direction.Type: ApplicationFiled: October 15, 2020Publication date: April 15, 2021Applicant: Micro Interventional Devices, Inc.Inventors: Michael P. WHITMAN, Peter DATCUK
