摘要
A delivery catheter system includes a guide catheter, an anchor catheter, a collapsible and expandable anchor, a balloon formed from a portion of the positioning catheter, and a needle. The anchor may be for anchoring a prosthetic heart valve in a native heart valve. The anchor may be configured to be received within the anchor catheter. The balloon may be inflated or deflated and provide mechanical support to enable the needle to pierce a ventricle wall. A metallic guide wire can simultaneously be inserted through the aorta to outline the heart when viewed through fluoroscopic imaging.
