A medical anchor device () for securing a medical article to a subject comprising an upper medical article attachment portion () and a lower insertion portion () for securing the medical anchor device () to the subject wherein the insertion portion () comprises a spiral anchor () so that the medical anchor device () is securable to and detachable from the subject by rotating the medical anchor device () in a clockwise or an anti-clockwise manner as required by the direction of the spiral anchor ().

Medical anchor device

Embodiments hereof relate to methods of delivering a valve prosthesis to an annulus of a native valve of a heart, the native valve having chordae tendineae. A chordae management catheter is positioned within a ventricle of the heart, the chordae management catheter having a displacement component at a distal end thereof. The displacement component has an annular shape and defines a central lumen therethrough. The displacement component is radially expanded to push chordae tendineae within the ventricle radially outward. A valve delivery system is introduced into the ventricle of the heart via a ventricular wall of the heart. The valve delivery system has the valve prosthesis at a distal portion thereof. The valve delivery system is advanced through the central lumen of the radially expanded displacement component towards the annulus of the native valve of the heart. The valve prosthesis is deployed into apposition with the annulus of the native valve.

Chordae tendineae management devices for use with a valve prosthesis delivery system and methods of use thereof

Embodiments hereof relate methods of delivering a valve prosthesis to an annulus of a native valve of a heart. A valve delivery system is introduced into a ventricle of the heart via a ventricular wall of the heart. The valve delivery system has a displacement component at the distal portion thereof. The valve prosthesis is in a delivery configuration and the displacement component is in a delivery state in which the displacement component has a first outer diameter. While the valve prosthesis is in the delivery configuration, the displacement component of the valve delivery system is radially expanded into an expanded state in which the displacement component has a second outer diameter greater than the first outer diameter. The valve delivery system is advanced towards the annulus of the native valve of the heart with the displacement component in the expanded state to displace chordae tendineae.
