Patent number: 12357462Abstract: Methods and devices for transvascular prosthetic chordae tendinea implantation are disclosed. A catheter is advanced into the left atrium, through the mitral valve, and into the left ventricle. A ventricular anchor is deployed from the catheter and into a wall of the left ventricle, leaving a ventricular suture attached to the ventricular anchor and extending proximally through the catheter. A leaflet anchor is deployed to secure a mitral valve leaflet to a leaflet suture, with the leaflet suture extending proximally through the catheter. The leaflet suture is secured to the ventricular suture to limit a range of travel of the leaflet in the direction of the left atrium. Also disclosed is an assembled in situ mitral valve leaflet restraint, having a neo papillary muscle and a neo chordae tendinea.Type: GrantFiled: February 8, 2024Date of Patent: July 15, 2025Assignee: Pipeline Medical Technologies, Inc.Inventors: Gordon B.

Publication number: 20250186052Abstract: A method is used to occlude a left atrial appendage (LAA) and other cavities or openings within a body. The method may include an implant configured to be deployed within the LAA or other cavity, configured to be expanded or moved against a wall portion of the LAA or other cavity, and configured to twist at least a portion of the LAA or other cavity when the implant is rotated. Thereafter, one or more securing elements, staples, sutures, or other fasteners can be implanted in the gathered tissue to hold the tissue in the gathered state, thereby occluding the opening of the LAA or other cavity. The opening of the LAA or other cavity may be occluded by elongating or otherwise reshaping the opening using an implant device, and securing the opening in the occluded state.Type: ApplicationFiled: February 14, 2025Publication date: June 12, 2025Inventors: Randall T.

Patent number: 12318296Abstract: This disclosure includes apparatuses and techniques to access the right ventricle via trans-femoral vein threading a catheter or catheters to the apex or bottom of the right ventricle. Piercing through the venous or right side of the heart in the interventricular septal wall to access the left ventricle a catheter can be passed to turn upward pointing to the mitral valve. From this access point in the left ventricle the flail mitral leaflet can be sutured and tethered pulling it back into position and reattached with a grounding anchor in the right ventricle or imbedding the anchor into the septal wall. The interventricular septal wall crossing technique could include the passing of a coaxial catheter through the first access catheter where the first access catheter could act as a guide to direct the internal or second coaxial catheter toward the flail mitral leaflet.Type: GrantFiled: June 15, 2023Date of Patent: June 3, 2025Assignee: Pipeline Medical Technologies, Inc.Inventors: Steven F. Bolling, Randall T. Lashinski

Publication number: 20250143713Abstract: A method includes inserting a contact member into an anatomical cavity. The contact member is rotated within the anatomical cavity through a first range of angular motion and engages tissue of the anatomical cavity during such rotation, such that rotation of the contact member within the anatomical cavity through the first range of angular motion causes torsional deformation of the anatomical cavity. The contact member is moved longitudinally through a first range of longitudinal motion after rotating the contact member within the anatomical cavity through the first range of angular motion, thereby causing longitudinal deformation of the anatomical cavity. A position of the contact member is secured relative to the tissue, thereby maintaining the torsional and longitudinal deformation of the tissue.Type: ApplicationFiled: December 23, 2024Publication date: May 8, 2025Inventors: Randall T. Lashinski, Joshua J. Dwork, Finn Olavi Rinne, Padraig J. Savage, Estella JingYe Wong

Publication number: 20240164892Abstract: An implantable prosthetic valve has an in situ formable support structure. The valve comprises a prosthetic valve, having a base and at least one flow occluder. A first flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The first component extends proximally of the base of the valve. A second flexible component is incapable of retaining the valve at a functional site in the arterial vasculature. The second component extends distally of the base of the valve. At least one rigidity component combines with at least one of the first and second flexible components to impart sufficient rigidity to the first or second components to retain the valve at the site.Type: ApplicationFiled: January 26, 2024Publication date: May 23, 2024Applicant: Speyside Medical, LLCInventors: Randall T.
