Side-delivered transcatheter heart valve replacement

机译:侧置经导管心脏瓣膜置换术

摘要

The invention relates to a transcatheter heart valve replacement (A61F2/2412), and in particular a side delivered transcatheter prosthetic valve having a tubular frame with a flow control component mounted within the tubular frame and configured to permit blood flow in a first direction through an inflow end of the valve and block blood flow in a second direction, opposite the first direction, through an outflow end of the valve, wherein the valve is compressible to a compressed configuration for introduction into the body using a delivery catheter for implanting at a desired location in the body, said compressed configuration having a long-axis oriented at an intersecting angle of between 45-135 degrees to the first direction, and expandable to an expanded configuration having a long-axis oriented at an intersecting angle of between 45-135 degrees to the first direction, wherein the long-axis of the compressed configuration of the valve is substantially parallel to a length-wise cylindrical axis of the delivery catheter, and wherein the valve has a height of about 5-60 mm and a diameter of about 25-80 mm.
