| 20100249915 | VALVE PROSTHESIS WITH MOVABLY ATTACHED CLASPERS WITH APEX - A valve prosthesis, implantation device, and methods for use are provided. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis. Alternative designs of the devices allow different methods for minimally invasive implantation of a sutureless valve prosthesis, including transapical and transcatheter approaches. Also provided is a delivery device for delivery of a medical prosthesis though minimally invasive means. | 09-30-2010 |
| 20100249916 | METHODS AND DEVICES FOR TRANSAPICAL DELIVERY OF A SUTURELESS VALVE PROSTHESIS - A method for delivering a sutureless cardiac valve prosthesis using a transapical approach is provided. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis within the native cardiac valve, minimizing the extent of imaging necessary. | 09-30-2010 |
| 20100249917 | Methods for Delivery of a Sutureless Pulmonary or Mitral Valve - Methods for delivering a sutureless pulmonary or mitral valve prosthesis using a transcatheter approach are provided. The implantation devices utilize movable claspers for both positioning and anchoring the valve prostheses within the native cardiac valve, minimizing the extent of imaging necessary. | 09-30-2010 |
| 20100249918 | DEVICES AND METHODS FOR DELIVERY OF AORTIC AND MITRAL VALVE PROSTHESES - A valve prosthesis and implantation device, and methods for use are provided. The devices described herein may be used for transcatheter delivery of an aortic valve prosthesis or transapical delivery of a mitral valve prosthesis. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis, reducing the extent of imaging needed during the implantation procedure. | 09-30-2010 |

| 20090097551 | Methods for Efficient Bandwidth Scaling of Compressed Video Data - The present invention relates to systems and methods for efficient bit rate alteration of a bitstream to match an available channel capacity. The efficient bit rate alteration includes selective re-quantization of the compressed bitstream. Selective re-quantization according to the present invention applies multiple re-quantization schemes to different portions of a bitstream. In one embodiment, the multiple re-quantization schemes each have a different computational load. By selectively choosing which type of re-quantization is performed on each portion, efficient bandwidth scaling and data transmission may be achieved both when computational capacity is limited and when video data integrity is important. | 04-16-2009 |
