Valvuloplasty Catheter |
| 摘要 |
The present invention provides an aortic valvuloplasty catheter which, in one preferred embodiment, has a tapered distal balloon segment that anchors within the left ventricle outflow track of the patient's heart and a rounded proximal segment which conforms to the aortic sinuses forcing the valve leaflets open. In addition, this embodiment of the valvuloplasty catheter includes a fiber-based balloon membrane, a distal pigtail end hole catheter tip, and a catheter sheath. |

1. A method for dilating heart valve leaflets comprising:
providing a catheter having a balloon; said balloon having a proximal section and a distal section; inflating said balloon to a first pressure in which said distal section engages a ventricle outflow tract while maintaining said proximal section in a non-fully expanded configuration; positioning said distal section upstream and adjacent to said valve leaflets so as to prevent migration of said balloon; dilating heart valve leaflets with said proximal section by further inflating said balloon to a second pressure higher than said first pressure. |
