| 20090030503 | METHOD AND APPARATUS FOR PERCUTANEOUS AORTIC VALVE REPLACEMENT - A method for percutaneous aortic valve (PAV) replacement and a temporary aortic valve used to facilitate the same. The temporary valve is comprised of a reversibly expandable occluding means, such as balloons, surrounding a central catheter mechanism. The temporary valve is positioned within the ascending aorta, just above and downstream from the coronary ostia. The occluding means is configured such that, when fully expanded against the aortic wall, gaps are left that promote continuous coronary perfusion during the cardiac cycle. The native aortic valve is next dilated, and then ablated through deployment of an ablation stent. The ablation stent displaces the native valve tissues and remains within the aortic annulus to receive and retain the PAV. The PAV can then be positioned and deployed within the ablation stent with precision and ease. Ablation of the native aortic valve removes the structural obstacles to precise PAV placement. The temporary aortic valve mediates the hemodynamic forces encountered by the surgeon following native valve ablation. The temporary valve also promotes patient stability through continuous coronary perfusion and a moderated transvavlular pressure gradient. Mathematical considerations for determining the optimum cross-sectional area for the temporary valve blood perfusion gaps are also described. | 01-29-2009 |
| 20090030510 | METHODS AND APPARATUS FOR PERCUTANEOUS AORTIC VALVE REPLACEMENT - A delivery system and method for percutaneous aortic valve (PAV) replacement and apparatus used therein. A temporary aortic valve comprised of a reversibly expandable occluding means, such as balloons, surrounds a central catheter mechanism. The temporary valve is positioned within the ascending aorta, just above and downstream from the coronary ostia. The occluding means is configured such that, when fully expanded against the aortic wall, gaps are left that promote continuous coronary perfusion during the cardiac cycle. The temporary valve with occluding means substitutes for the function of the native aortic valve during its replacement. The native aortic valve is next dilated, and then ablated through deployment of low profile, elongated, sequentially delivered stents. The ablation stent(s) displace the native valve tissues and remain within the aortic annulus to receive and provide a structure for retaining the PAV. The PAV is delivered, positioned and deployed within the ablation stent(s) at the aortic annulus with precision and relative ease. Ablation of the native aortic valve removes the structural obstacles to precise PAV placement. The temporary aortic valve mediates the hemodynamic forces upon the devices as encountered by the surgeon following native valve ablation. The temporary valve also promotes patient stability through continuous coronary perfusion and a moderated transvalvular pressure gradient and regurgitation. Sequential delivery of low profile PAV components minimize the risk of trauma and injury to vascular tissues. Mathematical considerations for determining the optimum cross-sectional area for the temporary valve blood perfusion gaps are also described. | 01-29-2009 |
| 20120116439 | METHOD AND SYSTEM FOR BALLOON COUNTERPULSATION DURING AORTIC VALVE REPLACEMENT - Methods and systems for regulating aortic regurgitation during aortic valve replacement or repair procedures utilize a temporary aortic valve (TAV) catheter and a controller.

Exemplary balloon structures include multiple, independently inflatable balloons which are inflated in synchrony with the cardiac cycle by the controller. By controlling aortic regurgitation, the repair or replacement protocols can be conducted with less interference from blood flow. | 05-10-2012 |
