The intermediate portion extends between the first seal and the second seal. In one embodiment, a medical device and a hydrating fluid are present in a device-containing region between the intermediate portion and the delivery catheter. | 01-15-2009 |

The support frames may include a plurality of symmetrically arrayed interconnected U-shaped member structures. Preferred support frames are tubular structures enclosing a longitudinal axis and including a plurality of U-shaped member structures facing a distal or a proximal end of the support frame. Each U-shaped member structure may be connected to a single longitudinally adjacent U-shaped member facing in an opposite longitudinal direction, as well as two laterally adjacent U-shaped members. | 05-14-2009 |
| 20090132037 | Valve Frame - The disclosure relates to support frames for prosthetic implantable valves. The support frames may include a plurality of symmetrically arrayed interconnected U-shaped member structures. Preferred support frames are tubular structures enclosing a longitudinal axis and including a plurality of U-shaped member structures facing a distal or a proximal end of the support frame. Each U-shaped member structure may be connected to a single longitudinally adjacent U-shaped member facing in an opposite longitudinal direction, as well as two laterally adjacent U-shaped members. | 05-21-2009 |
| 20090138069 | Implantable Frame and Valve Design - Implantable prosthetic valves comprising support frames are provided. The support frames may include a plurality of symmetrically arrayed interconnected U-shaped member structures. Preferred support frames are tubular structures enclosing a longitudinal axis and including a plurality of U-shaped member structures facing a distal or a proximal end of the support frame.

| 20100057185 | Sliding Split-Sleeve Implant Compressor - A system and method for loading an endoprosthesis, such as a stent or valve, into an introducer is provided that permits interventionalists to load the endoprosthesis easily at the bedside. The system can include a compressor for compressing the endoprosthesis to a cross-sectional area less than the cross-sectional area of the introducer lumen. The compressor has a funnel portion at one end where the un-compressed endoprosthesis can be introduced and another end where the introducer and sleeves of a split sleeve device are inserted. The sleeves conform to the compressor passage and surround the endoprosthesis to collapse the endoprosthesis. The split sleeve device also includes a mounting device coupled to the sleeves. The endoprosthesis is compressed and loaded into the introducer by the relative movement of the mounting device and the compressor, where the endoprosthesis remains generally stationary while being compressed and loaded in order to avoid potentially compromising the endoprosthesis. | 03-04-2010 |

| 20110152902 | Method For Anchoring Occlusion Plug - A method for occluding a body vessel in a patient to block or reduce blood flow therethrough includes puncturing a blood vessel wall at a proximal vessel entry site with a hollow needle and extending the needle through the proximal entry site into the vessel lumen. The needle is extended through the vessel lumen and extended through the vessel wall at a distal vessel exit site into the extravascular space surrounding the distal vessel exit site. An expandable biocompatible material, such as expandable extracellular matrix (ECM) material, is then ejected though the distal end of the needle into the extravascular space. Then, while continuing to eject the expandable biocompatible plug material, the distal end of the needle is retracted back through the distal vessel exit site into the vessel lumen, such that the plug material continuously extends between the extravascular space surrounding the distal vessel exit site into the vessel lumen. When the plug material is delivered into the lumen of the vessel, the plug material expands, anchoring the plug material to the vessel wall, whereby the plug material forms an occluding plug in the vessel lumen blocking or reducing blood flow therethrough. | 06-23-2011 |
