This allows sufficient room for blood to flow back around the valve and perfuse the coronary arteries.
In the inflated embodiments described herein, the structure is added to the implant secondarily via the inflation wd data lifeguard bootable cd iso fluid.
See, for example, David.,.The suture material may range from.001.010 inches in diameter.Devices for providing such a seal will be described in more detail below.More preferably, a braided configuration is used that comprises between 8 and 32 wires or ribbon.The inflation tubes 320 are configured to delivery inflation media to the implant 100 and the control wire tubes 316 receive the control wires 230, which are coupled to the implant 100.The filter may require a support structure such as a stent or series of struts to provide dimensional integrity.The sliding occurs between the flexible membrane 340 and the inner surface 346 of the outer, retractable sheath 301.
In a third embodiment, the guidewire lumen 320.039.080 in diameter, so that the device may be delivered over a larger than standard guide wire, or a diagnostic catheter, such as a pig tail catheter.
Optionally a release agent may be used to facilitate this step.
This filtration device may be made from a woven or braided wire such as Nitinol or stainless steel, MP35N, polymeric fibers or other suitable material commonly used in medical devices.The smaller diameter tube 115 is then sewed to the middle portion of the inner diameter of the larger diameter fabric tube 106, in a shape producing three cusps near the top edge of the fabric tube 106.In this case, the axial force pushing the implant 100 away from the heart 10 is resisted by a normal force from the upper portion of the aortic root.As the implant is navigated to the site, attachment between the implant 100 and catheter 300 is important.In contrast, the inflation channel 120 of the distal ring 108 b is not in communication with the inflation channels 120 of the proximal ring 108 a and struts 114.
