Patent number: 11957578Abstract: To percutaneously deliver a replacement tricuspid valve, a cable is percutaneously positioned with a first end extending out of the venous vasculature at the neck, and a second end extending out of a femoral access point. An eyehook device is positioned over the first end. A tricuspid valve delivery device (TVDD) is advanced over the second end, and then advanced through an IVC into a right atrium. The eyehook device is advanced into the right ventricle, drawing an intermediate portion of the cable into the right ventricle. Contact between the distal end of the eyehook device and the right ventricle is maintained while the TVDD is pushed from the femoral vein. The intermediate portion of cable applies a force to a distal nose of the TVDD that causes the distal nose to be steered into a tricuspid valve annulus as the TVDD is advanced.Type: GrantFiled: December 14, 2021Date of Patent: April 16, 2024Assignee: Synecor LLCInventor: Richard S.

Patent number: 11883016Abstract: A method and apparatus for securing separate loops of suture with a coaxial mechanical fastener. Separate loops of suture extend from opposite ends of the mechanical fastener. A wire snare facilitates pulling the suture through the fastener. A suturing instrument provides for the infusion of pressurized physiologic solutions into the left ventricle so that the proper replacement suture length can be demonstrated real time prior to crimping the fastener. The instrument incorporates a slotted release site so that the fastener and suture can be released from the device tip once the fastener is secured. A method of securing suture coming from cardiac valve leaflets and or other structures like papillary muscles permits a more atraumatic orientation of the fastener coaxial with the suture strands.Type: GrantFiled: September 25, 2013Date of Patent: January 30, 2024Assignee: LSI Solutions, Inc.Inventors: Jude S. Sauer, Angelo Martellaro

Patent number: 11878131Abstract: A trans-atrial septal catheter system for delivery of a steerable sheath into the left atrium contains three components. The first component is a three-segmented needle-guide wire composed of a distal needle designed to flex sharply in relation to the conjoined looped guide wire segment after fossa ovalis puncture and needle advancement. The distal guide wire loops are advanced into the left atrium maintaining the angled needle in a central location relevant to the loops for preserving an atraumatic position while stabilizing the loops in the left atrium. The elongated proximal extra stiff guide wire segment is conjoined to the looped segment which crosses the fossa ovalis and extends proximally to become externalized to the femoral vein. This segment is extra stiff and significantly elongated to permit catheter and device exchanges. The guide wire serves as a support rail over which the dilator and sheath can be advanced into the left atrium.Type: GrantFiled: November 30, 2021Date of Patent: January 23, 2024Assignee: Boston Scientific Medical Device LimitedInventors: Wesley Robert Pedersen, Paul Sorajja

Patent number: 11871916Abstract: Vascular closure devices and methods for closing a blood vessel puncture site disposed at a distal end of a tissue tract are described. A combination of the body's own natural mechanism with chemical and/or biological agents is relied upon to accelerate the hemostatic process. Included are steps of introducing a closure device through the tissue tract and deploying an expansible member at a distal end of the device within the blood vessel to occlude the puncture site. A sealing member disposed proximal the expansible member is then displaced by retracting and tensioning a coil spring so as to expose a chemical and/or biological region or release region of the device. The retraction and tensioning of the coil spring is limited by a coupling member. Exposure of blood and tissue to the chemical and/or biological sealing member promotes the clotting processing to accelerate the occlusion process in the tract.Type: GrantFiled: July 15, 2022Date of Patent: January 16, 2024Assignee: Cardiva Medical, Inc.Inventors: Zia Yassinzadeh, Jeffrey I. Weitz, Alan Stafford
