MEDICAL GUIDEWIRE |
摘要 |
A guidewire system may include a guidewire having a relatively stiff proximal section and a relatively flexible distal section joined by a transition region, and a TAVI device slidably disposed on the guidewire. The guidewire may include an expandable element disposed about the transition region. The expandable element may be configured to expand from a collapsed configuration to an expanded configuration. The guidewire may include an expandable element disposed at the distal end. The distal section may be pre-configured to form more than one distal loop. A method of protecting an apex of a left ventricle during a TAVI procedure may include inserting a guidewire into the left ventricle, positioning a transition region adjacent the apex, expanding an expandable element such that the expandable element spans the apex, advancing a TAVI device distally over the guidewire to an aortic valve, and performing a TAVI procedure at the aortic valve. |

1. A guidewire system, comprising:
a guidewire having a proximal end, a distal end, and a length extending therebetween; wherein the guidewire includes a relatively stiff proximal section and a relatively flexible distal section joined by a transition region; and a TAVI device slidably disposed on the guidewire; wherein the guidewire includes an expandable element disposed about the transition region in a first position; wherein the expandable element is configured to expand from a collapsed configuration to an expanded configuration. |
