  • Publication number: 20240000564
    Abstract: A prosthetic heart valve including a stent frame and a valve structure. The valve structure is disposed within a lumen of the stent frame. The stent frame is configured to self-expand from a compressed condition for transluminal delivery. The stent frame has a lattice structure forming a tubular shape defining a circumference and a plurality of closed cells arranged to define a band exhibiting a variable radial stiffness. The prosthesis can be deployed such that the band applies a minimal force on to anatomical locations relating to the heart's conductive pathways. A region of the band otherwise having low radial stiffness is located at or over a conductive pathway upon final implant.

  • Publication number: 20230404754
    Abstract: A modular valve prosthesis includes an inflow stent, a valve component including a valve stent and a prosthetic valve, and an outflow stent. In a radially compressed delivery configuration, an inflow end of the valve stent is separated from an outflow end of the inflow stent and an outflow end of the valve stent is separated from an inflow end of the outflow stent. In a radially expanded deployed configuration, the inflow end of the valve stent is in contact with the outflow end of the inflow stent and the outflow end of the valve stent is in contact with the inflow end of the outflow stent. A delivery system includes a capsule including first, second and third sections and flexible first and second bands between respective sections. The modules of the modular valve prosthesis are aligned with the sections and gaps between the modules are aligned with the bands.

  • Publication number: 20220175521
    Abstract: Transcatheter aortic valve prostheses for improving the cardiac function of a patient suffering from coronary artery disease. Transcatheter aortic valve prostheses include a valve component and a frame. The valve component includes valve leaflets and a skirt. The frame includes access cells that improve access to a patient's coronary arteries if further intervention is required and/or includes a window or conduction protection cell that is oriented to align with a portion of conduction system of the heart in situ to reduce conduction disturbances of the anatomy. Suture patterns for attaching a commissure to a commissure post of the frame, and for attaching a tissue bumper to the commissure post, are also described.

  • Publication number: 20110066226
    Abstract: A venous valve is disclosed for implantation in and selectively restricting the outflow of blood from a penile vein to aid a user in achieving and/or maintaining an erection. The venous valve includes a self-expanding stent framework defining a blood flow lumen there through. The self-expanding stent framework is constructed to recoil from a radially compressed configuration in which the blood flow lumen is narrowed to restrict blood flow through the venous valve to a radially expanded configuration in which the blood flow lumen is fully open to permit unrestricted blood flow through the venous valve. A recoil delay component is attached to the self-expanding stent framework for slowing the recoil of the self-expanding stent framework to thereby provide an extended time period during which the blood flow lumen is narrowed and blood flow through the venous valve is restricted.

    Abstract: A catheter and guide wire exchange system including a catheter that has a guide wire lumen with a guide way extending along a length of the proximal shaft. A guide member is slidably disposed about the proximal shaft for directing a guide wire into or out of the guide way and the guide wire lumen. A transition section joins the trilumen proximal shaft to a coaxial distal shaft.

  • Publication number: 20040260329
    Abstract: A catheter and guide wire exchange system including a catheter having a guide wire lumen with a guide way extending along the length of a stiffened proximal shaft portion, and a guide member slidably disposed about the proximal shaft for directing a guide wire into or out of the guide way and the guide wire lumen. The proximal shaft may be slid through the guide member so that the guide wire is contained within the guide wire lumen distal to the guide member and with the guide wire and catheter being separated proximal of the guide member. The guide member has a decoupled body, that allows it to be rotated without affecting the guidewire direction through the guidemember.
