| 20100170919 | CONSTANT FORCE MATERIAL DELIVERY SYSTEM AND METHOD - Systems, devices, and methods are provided for dispensing material from a container. Devices can include driving means for providing one or more forces, and actuator means for activating the driving means whereby the driving means causes material to be dispensed from the container. | 07-08-2010 |
| 20100132892 | METHOD AND APPARATUS FOR MANUFACTURING AN ENDOVASCULAR GRAFT SECTION - A device and method for the manufacture of medical devices, specifically, endovascular grafts, or sections thereof. Layers of fusible material are disposed upon a shape forming member and seams formed between the layers in a configuration that can produce inflatable channels in desired portions of the graft. After creation of the seams, the fusible material of the inflatable channels may be fixed while the channels are in an expanded state. A five axis robotic seam forming apparatus may be used to create the seams in the layers of fusible material. | 06-03-2010 |
| 20100076481 | Inflatable Implant - Described is an inflatable implant suitable for placement in the human body and left there for an indeterminate and potentially lengthy period of time. The implant is one that has a low profile when introduced into the body and a larger profile when it is inflated with one or more filler materials. Depending upon design and use choices the delivered implant may be removable and adjustable in situ in size, position, location, form, and rigidity. Indeed, in some variations, the design of the implant may be such that it may be removed at a potentially fairly lengthy time after implantation. The implant includes at least one bladder wall that generally is at least partially non-elastic (or unexpandable) after the preselected size is reached. The bladder wall will define at least one fillable volume and may form more than one independent fillable volumes. The bladder wall, in some variations, may be partially elastic or expandable to permit adjustment of implant size or configuration after or during delivery. The implant may be used as a supporting structure in a variety of differing body tissues and structures, e.g., in the spine or as a prosthetic in plastic surgery. The implant may also be used in conjunction with other components (often having a springed bias) as a source of movement in controlling the opening of a lumen or duct, that is to say, as a type of on-off valve or as a controlled flow valve. The implant may be used as an occludant within, or adjacent to, a variety of natural or abnormal anatomical body openings, e.g., vascular and genital lumina, aneurysms, ducts, septal defects, fistulae, esophagus, etc. The wall and filler material may be selected to deliver treatment materials the locale of the implant site or to remove amounts of harmful materials from such a region. The implant may, with an appropriate filler material or bladder wall material, be used in cooperation with an appropriate radio frequency (RF) source to cause the increase of a localized internal temperature and a resulting tissue change such as coagulation, ablation, or the like. Methods of using the implant are also described. | 03-25-2010 |
| 20100016948 | ENDOVASCULAR GRAFT - An endovascular graft, which is configured to conform to the morphology of a vessel to be treated, includes a tubular ePTFE structure; an inflatable ePTFE structure disposed over at least a portion of the ePTFE tubular structure; and an injection port in fluid communication with the inflatable ePTFE structure for inflation of the inflatable ePTFE structure with an inflation medium. The inflatable ePTFE structure may be longitudinally disposed over the tubular ePTFE structure. The ePTFE structure may be a bifurcated structure having first and second bifurcated tubular structures, where the inflatable ePTFE structure is disposed over at least a portion of the first and second bifurcated tubular structures. | 01-21-2010 |
| 20100016943 | METHOD OF DELIVERING ADVANCED ENDOVASCULAR GRAFT - A flexible low profile delivery system for delivery of an expandable intracorporeal device, specifically, an endovascular graft, which has at least one belt circumferentially disposed about the device in a constraining configuration. The belt is released by a release member, such as a release wire, by retracting the wire from looped ends of the belt. Multiple belts can be used and can be released sequentially so as to control the order of release and placement of the endovascular graft. An outer protective sheath may be disposed about the endovascular graft while in a constrained state which must first be retracted or otherwise removed prior to release of the graft from a constrained state. The delivery system can be configured for delivery over a guiding device such as a guidewire. The delivery system can also be configured for delivery of bifurcated intracorporeal devices. | 01-21-2010 |
| 20100016942 | ADVANCED ENDOVASCULAR GRAFT DELIVERY SYSTEM AND METHOD OF TREATMENT - This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs. | 01-21-2010 |
| 20090264984 | ADVANCED ENDOVASCULAR GRAFT - This invention is a system for the treatment of body passageways; in particular, vessels with vascular disease. The system includes an endovascular graft with a low-profile delivery configuration and a deployed configuration in which it conforms to the morphology of the vessel or body passageway to be treated as well as various connector members and stents. The graft is made from an inflatable graft body section and may be bifurcated. One or more inflatable cuffs may be disposed at either end of the graft body section. At least one inflatable channel is disposed between and in fluid communication with the inflatable cuffs. | 10-22-2009 |
| 20090036973 | PTFE LAYERS AND METHODS OF MANUFACTURING - Thin PTFE layers are described having little or no node and fibril microstructure and methods of manufacturing PTFE layers are disclosed that allow for controllable permeability and porosity of the layers. In some embodiments, the PTFE layers may act as a barrier layer in an endovascular graft or other medical device. | 02-05-2009 |
| 20090036971 | PTFE LAYERS AND METHODS OF MANUFACTURING - Single, continuous PTFE layers having lateral zones of varied characteristics are described. Some of the lateral zone embodiments may include PTFE material having little or no nodal and fibril microstructure. Methods of manufacturing PTFE layers allow for controllable permeability and porosity of the layers, in addition to other characteristics. The characteristics may vary from one lateral zone of a PTFE layer to a second lateral zone of a PTFE layer. In some embodiments, the PTFE layers may act as a barrier layer in an endovascular graft or other medical device. | 02-05-2009 |
