Abstract
An occlusion device intended for blocking perivalvular leak channels that are found following heart valve implantation between the heart valve and the surrounding tissue. The occlusion device has a stent and a covering that is attached to the stent surface. A blocking fabric extends across the lumen of the stent to block blood flow. The stent pattern and wall structure provide for small radius of curvature bends to fill narrow channels that cause the perivalvular leaks.
Claims13
An occlusion device for occluding a perivalvular leak channel located along the perimeter of an implanted valve of the heart, said occlusion device comprising;
- A. an occlusion balloon having a first element of a holding assembly located at a proximal end of said occlusion balloon, said proximal end of said occlusion balloon having an open orifice,
- B. a stent permanently attached to said occlusion balloon, said occlusion balloon serving as a covering to prevent blood flow through a lumen of said stent in an expanded configuration,
- C. a delivery tube having a second element of said holding assembly located at a distal end of said delivery tube, said second element of said holding assembly being attachable to said first element of said holding assembly, said holding assembly holding said occlusion balloon into a sealing contact with said delivery tube for delivery of inflation fluid to said occlusion balloon to provide said occlusion balloon with an inflated volume, said first element of said holding assembly being detachable from said second element of said holding assembly,
- D. said occlusion balloon able to provide passage for unrestricted removal of said inflated volume out of said open orifice with said occlusion balloon detached from said delivery tube after said occlusion balloon has been inflated within the perivalvular leak channel and detached from said delivery tube with said stent remaining in said expanded configuration.
