Patent application number | Description | Published |
20090092676 | CROSS-LINKED POLYMER PARTICLES - Cross-linked polymer particles, as well as related compositions and methods, are disclosed. | 04-09-2009 |
20090099649 | MODULAR VASCULAR GRAFT FOR LOW PROFILE PERCUTANEOUS DELIVERY - A hybrid modular endovascular graft wherein a main graft is sized to span at least a portion of a target vessel lesion in a large percentage of patients. Graft extensions may be secured to the main graft to extend the main graft and provide a sealing function for some applications. | 04-16-2009 |
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 |
20110029297 | VIRTUAL PROTOTYPING AND TESTING FOR MEDICAL DEVICE DEVELOPMENT - A system and method of developing better-designed medical devices, particularly cardiovascular stents and endovascular grafts. The system comprises a geometry generator, a mesh generator, a stress/strain/deformation analyzer, and a visualization tool. In one embodiment, the geometry generator receives three-dimensional volumetric data of an anatomical feature and generates a geometric model. The mesh generator then receives such geometric model of an anatomical feature or an in vitro model and a geometric model of a candidate medical device. In another embodiment, the mesh generator only receives a geometric model of the candidate medical device. Using the geometric model(s) received, the mesh generator creates or generates a mesh or a finite element model. The stress/strain/deformation analyzer then receives the mesh, and the material models and loads of that mesh. Using analysis, preferably non-linear analysis, the stress/strain/deformation analyzer determines the predicted stresses, strains, and deformations on the candidate medical device. Such stresses, strains, and deformations may optionally be simulated visually using a visualization tool. | 02-03-2011 |
20110137404 | INFLATABLE POROUS IMPLANTS AND METHODS FOR DRUG DELIVERY - The present invention provides inflatable porous implants, such as grafts, stent-grafts, and bladders, as well as methods and kits for drug delivery. In particular, the grafts and stent-grafts of the present invention provide for the delivery of a therapeutic agent into a flow conduit in the body. The inflatable porous implants provide for direct delivery of larger, more precise dosages of drugs over longer administration periods into the body. Moreover, these inflatable porous implants are often flexible when inserted and have a low profile delivery configuration for easy placement. The implants of the present invention further provide a mechanical or structural function in addition to drug delivery in a single integrated structure. | 06-09-2011 |
20110196060 | NON-DEGRADABLE, LOW SWELLING, WATER SOLUBLE RADIOPAQUE HYDROGEL POLYMER - Hydrogel compositions prepared from amine components and glycidyl ether components are provided which are biocompatible and suitable for use in vivo due, in part, to their excellent stability. | 08-11-2011 |
20110218609 | FILL TUBE MANIFOLD AND DELIVERY METHODS FOR ENDOVASCULAR GRAFT - Some embodiments relate in part to endovascular prostheses and methods of deploying same. Embodiments may be directed more specifically to inflatable stent grafts and methods of positioning and deploying such devices within the body of a patient. Some embodiments include inflation devices and methods that allow an inflatable portion of an inflatable stent graft to be inflated from a desired location within the inflatable portion. | 09-08-2011 |
20120016457 | BARBED RADIALLY EXPANDABLE STENT WITH SLOTTED STRUTS - The present application is directed to a stent, and more particularly, a radially expandable stent including a proximal end, a distal end, a plurality of struts and a plurality of apices at each of the proximal and distal ends; a barb integrally formed as an extension on at least one strut and extending outwardly from a position on each strut; and at least one slot formed as an opening through at least one of the struts, where at least one of the proximal and distal apices are curved apices. | 01-19-2012 |
20120029625 | BARBED RADIALLY EXPANDABLE STENT - The present application is directed to a stent, and more particularly to a radially self-expandable metallic stent, including a serpentine configuration having a plurality of struts and having a plurality of proximal and distal apices; and a barb integrally formed as an extension of each strut and extending outwardly from a position on each strut; where the barb has an elevation angle with respect to a longitudinal axis of a strut from which the barb extends of about 10 degrees to about 45 degrees. | 02-02-2012 |
20120316854 | VIRTUAL PROTOTYPING AND TESTING FOR MEDICAL DEVICE DEVELOPMENT - A system and method of developing better-designed medical devices, particularly cardiovascular stents and endovascular grafts. The system comprises a geometry generator, a mesh generator, a stress/strain/deformation analyzer, and a visualization tool. Using analysis, preferably non-linear analysis, the stress/strain/deformation analyzer determines the predicted stresses, strains, and deformations on the candidate medical device. Such stresses, strains, and deformations may optionally be simulated visually using a visualization tool. | 12-13-2012 |
20130261734 | ADVANCED KINK RESISTANT STENT GRAFT - Stent-grafts for treating thoracic aortic aneurysms and abdominal aortic aneurysms include graft portions having inflatable channels and graft extensions. The graft extensions include an undulating wire stent and porous, but substantially fluid impermeable, polytetrafluoroethylene (PTFE) graft materials. | 10-03-2013 |
